Questions
Search or answers?
Use search when your product shows the sources or runs its own model. Use answers when you want a cited answer to show as it is.
Does the API keep our questions?
No. The API keeps no messages or answers, and nothing is used to train models. Data stays in the EU.
Which countries can we search?
GET /v1/countries lists them. In Finland and France you can also ask for the rules in force on a date.
Do we need a key for each endpoint?
No. One key works for search, answers and filters. Workspace admins revoke keys in the Control Room, and a revoked key stops working within two minutes.
Build on verified sources
API access is turned on per workspace.
