answers 402

Bundled execution of the Schema guard workflow - Contract-test a JSON payload in one call: validate it against your schema, infer the schema the payload actually implies, diff the two to expose drift, and return a normalized pretty-print. One x402 payment runs 4 underlying tools (json-validate, json-schema-infer, json-diff, json-format); partial-success per step.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
