The advertised product was: Parse any PDF (optimized for German business documents: invoices, contracts, official letters) into an arbitrary caller-defined JSON schema. Stateless, GDPR-friendly: documents are processed in memory and never stored.\n\n```json\n{\n  \"document_url\": \"https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf\",\n  \"schema\": {\n    \"properties\": {\n      \"sender_company\": {\n        \"type\": \"string\"\n      },\n      \"tax_id\": {\n        \"type\": \"string\"\n      },\n      \"total_amount\": {\n        \"type\": \"number\"\n      }\n    },\n    \"required\": [\n      \"sender_company\",\n      \"tax_id\",\n      \"total_amount\"\n    ],\n    \"type\": \"object\"\n  }\n}\n```\n\nThe payment settled and the request finished with HTTP 200 in 11.26 seconds.
