PAID $0.002 (x402, USDC on Base). Coerce near-miss LLM JSON to a JSON-Schema-conformant object: strip code fences/prose, fix trailing commas/quotes/unquoted keys, normalise Python literals, balance brackets, then coerce types, apply defaults, and drop extraneous keys. Returns the repaired object OR precise per-field errors. Args: json (the raw string), schema (a JSON Schema object). Without payment returns the x402 challenge.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| json | string | yes | The raw, possibly-malformed JSON text to repair. |
| schema | object | yes | A JSON Schema (draft 2020-12) object the result must conform to. |
| x_payment | string | no | x402 payment payload (base64) for this PAID check. If supplied it is forwarded as the X-PAYMENT header to settle the call and return the real result instead of a 402 challenge. Omit to get the price challenge first. |
