Pricing

Pay for what you produce. Validation and extraction stay free without a key (rate limited) so anyone can check a file. Everything below is self-service: checkout, key delivery, upgrades, cancellation and invoices happen without talking to anyone.

Prices exclude VAT. Billing, invoices and EU VAT are handled by Lemon Squeezy as merchant of record; you receive a compliant invoice for your own books.

How keys work

1. Checkout (the Free plan is a EUR 0 checkout: e-mail address, no card).
2. The confirmation page and e-mail contain a license key. That key is your API key: Authorization: Bearer <key>.
3. The key works immediately on /v1 and on /mcp. Check usage any time with GET /v1/usage or read the X-Usage-* response headers.
4. Upgrade, downgrade, cancel, retrieve your key or download invoices from the customer portal (link above and in every e-mail). A plan change applies to the key at the next call.

Quotas reset on the first day of each month (UTC). A key belongs to one subscription; buy several subscriptions if you need separate keys per product or team.

MCP

Two ways to use the server from an AI agent, both without contacting us:

• Your plan key: point the client at https://facturx-api.fly.dev/mcp with the header Authorization: Bearer <key>. Each successful tools/call counts as one document on the same quota as the REST API (tools/list, resources and failed calls are free). Client snippets on the MCP page.
• Per call, no subscription: through AgenticMarket, $0.05 per successful tool call, paid from the marketplace balance. Use the URL the marketplace gives you; no header needed.

What is a "document"

One successful call to generate, embed, or an authenticated validate / extract over REST, or one successful MCP tool call. A call that fails business rules (400, tool error) is not counted. Retries after a 5xx are not counted.

Fair use and data

• No document is stored; files are processed in memory and discarded.
• Logs keep the invoice number, the rule ids and timings for 30 days, never party data or amounts.
• Hosted in Paris (Fly.io cdg); processing stays in the EU.
• Abuse (key sharing across companies, scraping the anonymous endpoints) may lead to the key being disabled; the subscription is refunded pro rata in that case.
