Terms of Use

1. Purpose

These terms of use (the “Terms of Use”) define the conditions under which the Publisher makes the Atomios service available and those under which the User accesses it.

They apply to all means of access to the Service, whether free or paid.

The financial conditions (subscription, paid quotas, overages, prepaid wallet, termination of subscriptions) are the subject of the Terms of Sale, which supplement these Terms. In the event of a contradiction between the two documents on a financial matter, the Terms of Sale prevail.

2. Definitions

• Publisher: Maxence-Olivier Parlant, sole trader, identified in the Legal notice.
• Service: all the tools, interfaces, APIs and MCP servers accessible from the atomios.me domain.
• Tool: a single feature of the Service (identifier generation, data validation, conversions, Factur-X validation, etc.), with its own usage limits and, where applicable, its own subscription.
• User: any person accessing the Service, with or without an Account.
• Account: the personal space created by the User, allowing management of API Keys, subscriptions and the prepaid wallet.
• API Key: the authentication secret allowing the Service's APIs to be called.
• MCP: the access protocol allowing a software agent or automated assistant to use the Tools on behalf of the User.

3. Acceptance and modification

3.1 Acceptance

Accessing the Service entails full and unreserved acceptance of these Terms of Use. A User who does not agree to them must stop using the Service.

The Service is exclusively reserved for professionals, that is, natural or legal persons acting for purposes within their commercial, industrial, craft, professional or agricultural activity. It is not intended for consumers. By accessing the Service, the User declares that they act in this professional capacity.

A User who creates an Account on behalf of a legal entity declares that they have the authority to bind it.

3.2 Modification

The Publisher may modify these Terms of Use at any time, in particular to reflect technical, regulatory or offering changes.

Any substantial modification is brought to the attention of Users holding an Account by email, with thirty (30) days' notice before it takes effect. Continued use of the Service beyond that date constitutes acceptance. Failing acceptance, the User may terminate under the conditions set out in the Terms of Sale.

Non-substantial modifications (editorial corrections, clarifications, link updates) take effect upon publication.

The date of last update appears at the top of this document.

4. Description of the Service

Atomios makes available a portfolio of technical utility Tools. Each Tool is accessible in three distinct forms, subject to the same Terms of Use but to different usage limits.

4.1 Web tools

Some Tools are accessible directly from the site, without creating an Account. This access is provided for demonstration and occasional use. It is capped per session by means of a technical counter and grants no guarantee of availability, retention or traceability.

Uses made through this channel are not recorded as evidence. In particular, Factur-X calls made from the demonstration interface generate no entry in the audit log and cannot serve as proof.

4.2 API

Programmatic access to the Tools is carried out by means of an API Key attached to an Account. It is subject to a quota, free or subscribed, under the conditions defined in the Terms of Sale.

4.3 MCP

The Tools are also exposed via the MCP protocol, allowing their use by software agents. This access is deducted from a shared prepaid wallet, under the conditions defined in the Terms of Sale and in §16 hereof.

5. Account

5.1 Creation

Creating an Account requires a valid email address and a password. The User undertakes to provide accurate information and to keep it up to date, in particular their email address, which constitutes the channel for quota, billing and security alert notifications.

A single User may not hold multiple Accounts for the purpose of circumventing the free quotas.

5.2 Account security

The User is solely responsible for the confidentiality of their credentials and for any activity carried out from their Account. They undertake to choose a strong password, not to reuse it, and to inform the Publisher without delay of any suspected compromise at [email protected].

5.3 Sessions

Authentication to the management area relies on a session token with a validity period of seven (7) days.

Important information: this token is not revocable server-side. In the event of theft or compromise, changing the password does not invalidate sessions already open, which remain valid until their natural expiry. The User is advised not to open a session from a shared or untrusted device, and to report any compromise immediately so that the Publisher can take the appropriate measures on the Account concerned.

6. API Keys and MCP tokens

6.1 Nature

API Keys and MCP tokens are authentication secrets. They are displayed in clear text only once, at the time of their creation. The Publisher retains only a cryptographic fingerprint of them and cannot therefore restore them.

6.2 Responsibility

Any call made by means of a valid API Key or token is deemed to originate from the User holding the Account to which it is attached, and is attributable to them, including in terms of quota consumption and billing.

The User undertakes not to transmit their Keys to third parties, not to include them in public source code, in a versioned repository or in a client run in the browser, and to revoke them without delay in case of doubt.

6.3 Labels

The labels associated with the Keys are entered freely by the User. The User refrains from including personal data, secrets or confidential information in them.

6.4 Revocation

The User may revoke their Keys at any time from their management area. Revocation is immediate and irreversible.

7. Quotas and usage limits

Each Tool has its own quota. The methods of accounting, the thresholds and the consequences of an overage are defined in the Terms of Sale.

Reaching a free quota results in the refusal of subsequent calls until the period renews or a subscription is taken out. This refusal is normal operation of the Service and constitutes neither an unavailability nor a breach by the Publisher.

Rate limits may be applied in order to preserve the stability of the Service. They may be adjusted without notice in the event of abnormal use.

8. Financial conditions

The prices and the terms of subscription, billing, overage, top-up of the prepaid wallet and termination are defined in the Terms of Sale.

The applicable prices are those displayed online on the day of subscription.

9. Acceptable use rules

9.1 Prohibited uses

The User shall refrain from:

• using the Service for unlawful purposes, or to process unlawful content;
• attempting to access data or Accounts that are not their own;
• circumventing or attempting to circumvent the quota, rate-limiting or billing mechanisms, in particular by multiplying Accounts or sessions;
• submitting abnormal loads, massive automated requests or any traffic to the Service liable to degrade its availability for other Users;
• carrying out reverse engineering, decompilation or systematic extraction of the Service's content, except within the mandatory limits provided by law;
• harming the security or integrity of the Service, or conducting intrusion tests on it without prior written authorisation.

9.2 Security testing

Any vulnerability research must be the subject of prior written authorisation. Findings are reported to [email protected] before any public disclosure.

9.3 Authorised integration and prohibited resale

Use of the Tools under a subscription or a wallet is reserved for the Account holder and their internal team. The holder is further authorised to integrate the Tools into their own applications, products or services, including for commercial purposes.

Conversely, it is strictly prohibited to resell, redistribute, sublicense or make available to third parties direct access to the Atomios Tools, whether for a fee or free of charge, in particular by exposing the Publisher's endpoints, as-is or by simple relay, as a standalone offering. It is thus prohibited to derive a margin from the mere provision of the Publisher's endpoints.

The distinction is as follows: authorised is the integration of the Tools as a component of a product or service with the User's own added value; prohibited is the provision, directly or by relay, of raw access to the Publisher's Tools as a service in itself.

This clause applies exclusively to the Tools published by Atomios. Any tools offered by third-party providers on the Service will be governed by the specific conditions defined by those providers.

9.4 Sanctions

Any breach may result in the measures provided for in §17.

10. Availability and evolution of the Service

10.1 Availability

The Publisher implements reasonable means to ensure the availability and performance of the Service. This is a best-efforts obligation. No service level (SLA), no availability rate and no restoration time are guaranteed.

The Service may be interrupted at any time for maintenance, updates, corrections or for security reasons. The Publisher endeavours, where circumstances permit, to inform Users of significant scheduled interruptions.

The Service relies on third-party hosting and routing providers identified in the Legal notice. A failure of one of them may affect availability without the Publisher's liability being incurred beyond the limits provided for in §14.

10.2 Evolution

The Publisher may evolve the Service at any time: add, modify or withdraw Tools, evolve the interfaces and response formats, or introduce new features, including features provided by third parties, which would then be subject to separate conditions brought to the attention of Users.

In the event of the withdrawal of a Tool that is the subject of an active subscription, the Publisher informs the Users concerned and the financial consequences are settled in accordance with the Terms of Sale.

10.3 Versions and compatibility

Non-backward-compatible modifications to the programmatic interfaces are the subject of prior notice by email to Users holding an active API Key. The Publisher endeavours to maintain a reasonable compatibility period, without this constituting a commitment as to duration.

11. Intellectual property

11.1 Publisher's rights

The Service, its structure, its code, its interfaces, its documentation and its graphic elements are protected by intellectual-property law and remain the exclusive property of the Publisher or its licensors.

The User benefits from a personal, non-exclusive, non-transferable and revocable right of use, limited to the duration of their access to the Service and to the purposes provided for herein.

11.2 Third-party standards and frameworks

The technical specifications, standards and frameworks implemented by certain Tools, notably the EN 16931 standard and the Factur-X specifications, remain the property of their issuing bodies. The Service provides an implementation of them; it provides neither their distribution nor their representation.

11.3 Results

The results produced by the Tools from the data submitted by the User may be used freely by the latter, including for commercial purposes, subject to compliance with these Terms of Use.

12. Data submitted by the User

12.1 Ownership

The data that the User submits to the Service remains their property. The Publisher uses it only to perform the requested service.

12.2 No retention

Save any contrary provision specific to a Tool, the data submitted is not retained beyond the processing of the request. In particular, for the Factur-X Tool, neither the incoming document nor the structured content extracted from it is retained: only a cryptographic fingerprint of the input and the response issued are recorded, under the conditions described in §15 and in the Terms of Sale.

12.3 User's warranties

The User warrants that they hold the necessary rights over the data they submit and that its processing by the Service does not contravene any legal, contractual or regulatory obligation incumbent upon them, in particular as regards professional secrecy and the protection of personal data.

The User refrains from submitting to the Service data whose sensitivity exceeds the level of protection described in the Privacy Policy.

13. Personal data and cookies

The processing operations carried out by the Publisher, their purposes, their legal bases, their retention periods and the means of exercising rights are described in the Privacy Policy. The trackers are described in the Cookie Policy.

When the User submits to the Service personal data for which they are the controller, the Publisher acts as a processor within the meaning of the GDPR. The conditions of this processing are defined in the data processing agreement appended to the Terms of Sale.

14. Warranties and liability

14.1 Nature of the commitments

The Publisher is bound by a best-efforts obligation. The Service is provided as-is. The Publisher does not warrant that it will be free of errors, uninterrupted, or that it will meet a particular need of the User.

The Tools are technical assistance instruments. They constitute neither legal advice, nor tax advice, nor accounting advice, and do not relieve the User of any of their own obligations. It is the User's responsibility to verify the suitability of the results to their needs and to keep their own controls.

14.2 Free access

The web Tools accessible without an Account and the free quotas are provided without any warranty, for evaluation purposes. The Publisher's liability cannot be incurred on account of their use.

14.3 Exclusions

The Publisher is not liable for:

• the consequences of use of the Service not compliant with these Terms of Use or its documentation;
• the consequences of a compromise of the User's credentials or Keys, save for fault attributable to the Publisher;
• damage resulting from the failure of a network, equipment or third-party provider;
• indirect damage, such as loss of operations, loss of turnover, harm to image, loss of data, or the sanctions, penalties and tax reassessments borne by the User.

14.4 Cap

In any event, and except in cases where the law prohibits it, the Publisher's liability hereunder is capped at the total amount of the sums actually paid by the User during the twelve (12) months preceding the triggering event, and at one hundred (100) euros where the User uses only free access.

15. Special provisions for the Factur-X Tool

The Factur-X Tool is subject to special conditions detailed in an annex to the Terms of Sale, which prevail over these Terms as regards it. The following principles are recalled here.

15.1 Scope

The Tool is a technical building block for the validation of electronic invoices. The Publisher is not an Approved Platform, nor a dematerialisation operator. The Tool provides neither transport, nor deposit, nor directory, nor e-reporting, nor connection to any public platform. Nor does it provide the generation of documents, or the checking of their compliance with the PDF/A-3 format.

15.2 Scope of the result

The result issued is never a firm affirmation of compliance. A detected anomaly is certain; the absence of a detected anomaly does not guarantee that an Approved Platform, a commercial partner or the administration will accept the document. The coverage of the rules evaluated is declared with each result.

15.3 Audit log

Each response issued by the API gives rise, as far as possible, to the recording of a chained and encrypted trace allowing any subsequent alteration to be detected. This recording is carried out to the best of the available means and does not constitute a guarantee of proof. The timestamp applied is a server timestamp, not qualified within the meaning of the eIDAS regulation.

15.4 User's responsibility

The User remains solely responsible for the compliance of their invoicing and for compliance with their legal and tax obligations.

16. Special provisions for MCP access

MCP access allows software agents to invoke the Tools on behalf of the User.

The User acknowledges that an automated agent may generate a high and unpredictable volume of requests. It is their responsibility to supervise the agents to which they grant access, to define their limits, and to monitor the balance of their prepaid wallet. Any consumption generated by an authorised agent is attributable to the User, including where it results from unanticipated behaviour of that agent.

The authorisations granted to an agent may be revoked at any time from the management area.

17. Suspension, termination and closure

17.1 Suspension by the Publisher

The Publisher may suspend all or part of access to the Service, without compensation, in the event of:

• breach of these Terms of Use, in particular the acceptable use rules;
• failure to pay under the conditions provided for in the Terms of Sale;
• use liable to compromise the security, stability or integrity of the Service;
• requisition by a competent authority.

Save in an emergency or a legal obligation, the Publisher informs the User beforehand and gives them the opportunity to remedy the breach.

17.2 Termination by the Publisher

In the event of a serious breach or a breach not remedied within fifteen (15) days following a formal notice, the Publisher may terminate access as of right.

17.3 Closure of the Account at the User's initiative

The User may request the closure of their Account.

Important information: this operation is not available in self-service in the management area. The request is made by email to [email protected] and is processed manually within a reasonable time. The financial consequences of closure, in particular the fate of an ongoing subscription and a prepaid balance, are governed by the Terms of Sale. The consequences as regards data are described in the Privacy Policy.

17.4 Inactivity

A free Account that has remained inactive, without any connection or authorised call, for a continuous period of twenty-four (24) months, may be closed by the Publisher. Two reminders are sent by email to the address attached to the Account, respectively sixty (60) days then thirty (30) days before closure, in order to allow the User to keep their Account by reconnecting to it. After that period, the Account and the associated data are deleted, subject to the data whose retention remains required under §17.5 and the Privacy Policy.

17.5 Effects

The cessation of access entails the revocation of the API Keys and MCP tokens. The stipulations which, by their nature, are intended to survive (intellectual property, liability, confidentiality, governing law, retention of the audit log) remain in force.

18. Force majeure

Neither party may be held liable for a breach resulting from an event of force majeure within the meaning of Article 1218 of the French Civil Code and the case law of the French courts.

19. Miscellaneous provisions

• Partial nullity. If a stipulation herein is held to be null or unenforceable, the other stipulations retain their full effect.
• Tolerance. The fact that the Publisher does not avail itself of a breach does not constitute a waiver.
• Assignment. The User may not assign their rights without prior written agreement. The Publisher may assign these Terms in the context of a transfer of its business, subject to informing the Users.
• Entirety. These Terms of Use, the Terms of Sale and their annexes, the Privacy Policy and the Cookie Policy express the entirety of the agreement between the parties concerning the Service.
• Language. In the event of translation, the French version prevails.

20. Governing law

These Terms of Use are governed by French law.

As the Service is reserved for professionals, the parties will endeavour to settle amicably any dispute relating to their interpretation or performance. Failing agreement, the dispute will be brought before the competent French courts under ordinary rules of law.
