Ask TypeSafe Jev typed questions about a piece of state and get calibrated probabilities back.

Send the content to judge as state (a string, or a JSON object/array for structured data) and a map of questions keyed by IDs you choose. All questions are answered in parallel against the same state, in one request, and cannot see each other's answers.

Question types:

• noul: a yes/no question. Returns noul, the probability of yes (0..1). Optional criteria { true, false } describes what yes and no mean.

• choice: pick one option. criteria maps option names to descriptions (or null), up to 255 options. Returns choice, probabilities per option and confidence.

• score: rate along ordered levels. criteria is an array of 2-10 level descriptions, lowest first. Returns score (a probability-weighted level index from 0, may fall between levels), legend, probabilities and confidence.

Question IDs are not shown to the model, so instructions must state the full question. Refer to parts of structured state with backticked paths such as ticket.messages[0].text. Ask one narrow judgment per question. model is optional and defaults to the server's configured model.

images (optional, up to 4 PNG, JPEG or WebP, 4 MiB each) are judged together with state; each is either { "path": "" } for a local file inside a directory the server allows (JEV_IMAGE_DIRS), or { "data": "data:image/png;base64,..." }. Only image-capable models accept images (for example cloudflare/clef or cloudflare/clef-flash through OpenRouter); other models reject them. Never put images inside state.

provider is optional; this server offers only "typesafe".

Ask TypeSafe Jev the same typed questions about many items (up to 100) in one call, for example to classify a list of tickets or to score every search result and sort them.

items is a list of { "state": ..., "id"?: "...", "images"?: [...] }; each item is judged on its own. questions and the optional model work exactly as in jev.evaluate and apply to every item. Use a choice question to classify, a score or noul question to rank, and several questions to tag.

Each item is a separate provider request and is billed separately. Every item is checked before anything is sent; one invalid item rejects the whole call. Returns results in input order: status "ok" with answers and usage, "error" with the item's own error, or "skipped" when an earlier error (for example authentication or no credits) would also have hit it. summary counts each status and usage adds up the successful items.

images (optional, up to 4 PNG, JPEG or WebP, 4 MiB each) are judged together with the item's state; each is either { "path": "" } for a local file inside a directory the server allows (JEV_IMAGE_DIRS), or { "data": "data:image/png;base64,..." }. Only image-capable models accept images (for example cloudflare/clef or cloudflare/clef-flash through OpenRouter); other models reject them. Never put images inside state.

List the model names and aliases each provider accepts in the model field, tagged with their provider. Pass provider to list one provider only. A provider that cannot be reached appears in errors instead of failing the whole list. provider is optional; this server offers only "typesafe".

Ask TypeSafe Jev one yes/no question about some state. Returns answer.noul, the probability of yes (0..1); 0.5 means equally likely, not "medium". Optional criteria { true, false } describes what yes and no mean.

Ask TypeSafe Jev to pick one option for some state. criteria maps option names to descriptions (or null), up to 255 options; include a "none" option when nothing may fit. Returns answer.choice, answer.probabilities per option and answer.confidence.
