How this service works
Extract strict, JSON-Schema-valid typed JSON from unstructured text or HTML. Failed extraction calls are not settled. Primary x402 V2 API for production agents.
Output
A JSON object whose shape is guaranteed to satisfy the caller-supplied JSON Schema (draft 2020-12). If extraction fails validation after repair iterations, the call is not settled. Returns typed, structured data ready for downstream use without additional parsing.
Example use cases
Example prompt
“Extract the product name, price, and availability from this HTML snippet and return it as strict JSON matching this schema: {"type":"object","properties":{"name":{"type":"string"},"price":{"type":"number"},"available":{"type":"boolean"}},"required":["name","price","available"]} — use auto input detection and allow up to 3 repair iterations.”
Technical details
Endpoint
POSThttps://schemasure.com/v2/extractWhen to prefer
Choose this endpoint when you need a hard guarantee that the returned JSON satisfies a specific schema — not just a best-effort parse. It is especially valuable for agentic pipelines where downstream code expects typed fields and cannot tolerate schema violations. The no-charge-on-failure model makes it safe to use in cost-sensitive workflows. Prefer it over general LLM extraction when schema strictness, repair logic, and deterministic output are required.
Side effects
- Input cannot be parsed into the target schema even after maxRepairs iterations — call is not settled and no charge is made
- Schema provided is invalid or not compatible with JSON Schema draft 2020-12 — extraction will fail
- Input is empty or below minLength of 1 character — rejected at validation
- Requested fields are entirely absent from the input content — output may be incomplete or extraction fails
- HTML input is too complex or obfuscated for the parser to extract meaningful content
