Briefing your AI on a French company

An AI asked what it knows about a company answers from memory. The briefing gives it today's official data, block by block, with what each block covers and what it does not say, and an instruction: stick to them and quote the source.

The problem: an AI that fills the gaps

From memory, an assistant mixes up two namesakes, quotes a three-year-old revenue figure or states that a company has no litigation when the source only covers part of the decisions. It does not say what it does not know.

The briefing fits in a few thousand characters. Each block states its status (served, partial, inconclusive absence, to be checked), the age of its data and its coverage; the opening instruction asks the AI to report that status rather than fill a gap, and to copy the source line at the end of its answer.

The call

Markdown by default, JSON with Accept: application/json. With a free key, a briefing counts as one call of the 150-call monthly quota; without an account, it is paid per call over x402. Language: langue=fr or langue=en, else the key's account language, else French.

What the briefing does not do

It names no natural person: no officers, no shareholders, no parties to decisions. A sole proprietorship gets a refusal, never charged.
It returns no verdict and no score: they remain sold separately, through /v1/intelligence/{siren} and /v1/score/defaillance/{siren}.

The briefing is written by code, from the official registers: no sentence is drafted by a model. What the AI then does with it is its own; the source line lets anyone check what it quotes.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Open today: 150 free calls a month with an account, on 106 of 122 routes (the price list says which), and pay-per-call over x402 (USDC or EURC), with no account except registry filings. Prepaid credits: card top-up is not open yet.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.

Frequently asked questions

Is the briefing written by an AI?

No. Every sentence is a constant in French or English, or a template filled by a register field. The caveats come from closed codes already served by the data routes.

Is the response signed?

Yes, like every paid response: the Ed25519 signature covers the Markdown bytes served, and the Source section carries a public verification link.
