Choose a model
Find a model, read its input schema and send only the fields it accepts.
Model catalog
Each model has a slug and an input schema. GET /api/v1/models lists them; GET /api/v1/models/{slug} returns one. The OpenAPI document exposes each input schema under x-models.
Input validation
Only the fields listed for a model are accepted. Unknown fields, missing required fields and values outside the allowed options are rejected with 400 INVALID_MODEL_INPUT.
