For AI agents: a documentation index is available at the root level at /llms.txt. Append /llms.txt to any URL for a page-level index, or .md for the markdown version of any page.
- Builder: Flow functions — the agent calls your HTTP endpoints mid-conversation. Structured requests (path, query and body parameters as JSON Schema), with each parameter bound to the model, to call context (caller, call, flow) or to a static value; values bound to context are never shown to the model. Attach a function to any agent with the HTTP Request node. See Call your backend.
- Builder: Functions (called by the model) and actions (run automatically around an agent’s turn) are now distinct concepts.
- Models: Settings a model doesn’t support — a temperature on a reasoning model, for example — are stripped automatically rather than failing the call; the builder hides them.
