API key as bearer token in Authorization header
Body
application/json
Show child attributes
Show child attributes
The content to evaluate: a plain string, or a JSON object or array of related context.
Images keyed by reference string, as in TypeSafe's API. Write a reference wherever the image belongs in state, instructions, or criteria; every asset must be referenced at least once, or the request fails with 400 naming the unused key. TypeSafe Jev endpoints receive assets as written and read a reference as a whole string value or inside longer text. Every other provider has each whole-string reference resolved to an image_url part before the request is sent, so it is accepted only where that provider reads image_url parts (top-level state items), and a reference inside longer text fails with 400. image_url parts and assets can be mixed in one request.

Provider routing preferences for the request.

Example:
{ "allow_fallbacks": true }
A unique identifier for grouping related requests (e.g., a conversation or agent workflow). Used for observability grouping in Broadcast and private logging; never sent to the provider. If provided in both the request body and the x-session-id header, the body value takes precedence. Maximum of 256 characters.
Maximum string length:
256Example:
"session-1234"
Metadata for observability and tracing. Known keys (trace_id, trace_name, span_name, generation_name, parent_span_id) have special handling. Additional keys are passed through as custom metadata to configured broadcast destinations.
