SchemaLock

https://doc-extract-api.thestarboy9696-4ef.workers.dev/ex...

SchemaLock — extract structured JSON from any PDF or image into a JSON Schema you supply, not limited to invoice/receipt/contract/resume. Unlike the fixed invoice/receipt/contract/resume endpoints, this accepts any JSON Schema — you define the fields. Same engine: raw file in, forced tool-use against your schema out. No semantic validation (schema-conformance, not fact-checking). Schema capped at 6000 chars; a rejected schema is a 400 and costs nothing.
