Create Decisions

OpenRouter Decisions API compatible endpoint for the typesafe/jev-* family of decision models (e.g. jev-1.13): given state (the state/text to be judged) and questions (a number of noul / choice / score type questions), the model returns structured answers. The request body is passed through byte-for-byte in the native OpenRouter format; only model is rewritten according to the channel mapping.

Constraints: model, state, and questions are required; each question needs type (noul | choice | score) and instructions, and choice/score also require non-empty criteria; streaming is not supported (stream must be omitted or false). jev models can only be called on this endpoint; on /v1/chat/completions they return 400 unsupported_endpoint_for_model.

Billing is based on the response usage.input_tokens / output_tokens multiplied by this site's prices; usage.cost in the response is the provider's cost field, not the amount charged by this site.

Source of truth in code: router/relay-router.go (decisionsRouter.POST("/decisions")), relay/decisions_handler.go, dto/decisions.go, docs/decisions-api.md.

Model name: the public model name on this site is jev-1.13 (jev-1.13 is also accepted). The model field in the response is the full version name returned by the upstream.

Last verified/modified: 2026-09-28 (API Base URL unified to https://api.crazyrouter.com; example model names follow what GET /v1/models returns); tested: stream=true / missing questions both return 400 invalid_request_params; jev models on /v1/chat/completions return 400 unsupported_endpoint_for_model; api.crazyrouter.com now allows this path
