Verdicts
TheFork B2B API
A venue-side API with a generated OpenAPI 3.1 schema, an llms.txt written for agents and nine OAuth scopes down to read-only availability. It acts for restaurants and their vendors, not diners, needs partner approval, cannot take card guarantees, and has no public status page, changelog or published prices.
Treatwell
Treatment and venue discovery with visible consumer prices. Open agent booking access was not verified.
Before you call either
TheFork B2B API
- Read hasPaymentGuaranteeRequirement in the timeslots response before booking, since the API cannot take a card
- Check the status field after creating a reservation and treat REQUESTED as unconfirmed
- Send the timeslot datetime unchanged as mealDate, because times are the restaurant's local time
- Check for an existing reservation before retrying a failed POST, as no idempotency key exists and 409 signals DOUBLE_BOOKING
- Cache the access token for its 8,600 seconds and do not request a new one while it is valid
Treatwell
- Hand the final booking to the person unless Treatwell has approved an integration.
- Check the selected venue’s cancellation deadline and payment option.
