Which provider answers the chat. "Use" switches immediately, with that provider's saved model. "Edit" loads it into the form below.
| Provider | Key | Model | Plan |
|---|
Applies to every provider.
When the bot cannot answer from the context, the chat shows this message and these buttons instead of the model's wording. Empty links are hidden.
| Button label | Link |
|---|
Shown as buttons under the chat. A click answers with this text instantly — no model call, no cost. Still recorded in the conversation history and counted by the rate limits.
reCAPTCHA v3 scores every message invisibly. Below the minimum score the chat shows the v2 "I'm not a robot" checkbox (if v2 keys are set); a passed checkbox trusts that conversation for 10 minutes. Keys come from google.com/recaptcha/admin — v3 and v2 are separate key pairs. Google accepts domains only (no IPs): with a bare IP, turn off "Verify the origin of reCAPTCHA solutions" in the key settings.
Everything the bot is allowed to answer from. Sent with every message (cached where the provider supports it).
Every message, user and assistant, including refused ones (rate limit, captcha, provider error).

Public endpoints (/api/*) are what another website uses — they return the conversation only. Admin endpoints (/api/admin/*) need the x-api-key-admin-chatbot header. Every operation has a Try it form. (OpenAPI 3.1 — import into Swagger UI or Postman).
