StatusUnknown

Output

Returns a schema-normalized JSON object where all fields have been coerced to their declared types, required fields are validated, defaults applied, and non-conforming values flagged or rejected, along with a normalization receipt.

Example use cases

Example prompt

“Before you save this user-submitted payload to the database, normalize it against our declared JSON Schema — coerce types, fill in defaults, and reject anything that can't be made to conform.”

When to prefer

Choose this endpoint when you need to enforce strict schema conformance on data that originated from an untrusted source, a language model, or user input before it is written to a database, passed to a downstream API, or used in an agentic chain. It is especially valuable in multi-step agent pipelines where one model's output feeds the next step's input and type safety is critical.

Side effects

Payload cannot be coerced to declared schema — returns validation error with field-level details
Schema is invalid or unparseable — returns schema parse error
Input data is completely unparseable — returns extraction failure
Missing required fields with no default — returns missing field error
Service unavailable on cold start (Render free tier) — returns 503 or timeout
