Precellence for AI agents and assistants
An AI agent or assistant can get our prices including VAT per vehicle with GET /api/public/quote, read our conditions with GET /api/public/conditions, then send the traveller to a pre-filled booking link. Read-only, no key or account, no personal data, limited to 30 units per hour per IP address. Booking and payment always happen on our website.

Pre-filled booking link
https://precellence-service.com/reservation?from={from}&to={to}&date={YYYY-MM-DD}&time={HH:MM}&pax={1-7}&class={business|electric|first|van|ev}&lang={fr|en|ar}

Opens the booking form with the trip filled in and the class selected; the price is requested again from the server. Nothing is stored before the traveller clicks "Continue".
Rules and limits
- Limit: 30 units per hour and 200 per day per IP address; a computed request costs 1 unit, plus 1 if Google has to locate the addresses and 1 if it has to compute the route (known places and routes are cached). Beyond: response 429 with a Retry-After header.
- Identical request = identical answer for 10 minutes (free); conditions cached 1 h.
- Open CORS for reading (GET); no key, no cookie, nothing is stored; logs keep neither the address nor the IP address.
- Address too vague, pickup in less than 2 h, prestige car, destination not published: response "on_request" with a plain reason (code + message) and our contacts.
- Payment never goes through the assistant: the traveller books and pays on the website, where the same price is recomputed and guaranteed for 20 minutes.
