How this service works
Extract fields from a PDF or long document into JSON matching your schema. Every returned field carries a source quote and page number, checked against the document text; fields whose quote isn't found are dropped, not guessed. Input: public PDF/HTML URL or pasted text, up to 40 pages. Use for invoices, spec sheets, RFPs, filings. Not for scanned/image PDFs (no OCR), login/paywalled sources, or financial/legal advice. Errors aren't charged. No API key.
Output
A JSON object matching the caller's provided schema, where each top-level field is populated with the extracted value plus a source_quote (verbatim text from the document) and page_number indicating where the value was found. Fields that cannot be located return null with an appropriate note.
Example use cases
Extract fields from 10-K filing
“I need you to extract the following fields from this SEC 10-K filing at https://sec.gov/files/company-10k.pdf into structured JSON: company name, fiscal year, total revenue, operating income, total assets, and risk factors summary. Include the exact source quote and page number for each field.”
Parse contract key terms
“Can you pull the key terms out of this contract PDF at https://example.com/contract.pdf? I want: party names, effective date, contract value, termination clauses, and governing law — all with the exact quote and page number from the document so I can verify each one.”
Structure research paper metadata
“Extract the following fields from this research paper PDF at https://arxiv.org/pdf/2401.12345.pdf: title, authors, abstract, methodology summary, dataset used, and main findings. Return each field with the exact quote and page number it came from.”

Endpoint
POSThttps://x402.hydratrader.ai/v1/document-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to extract specific, named fields from a text-based PDF or document and require verifiable source citations (quote + page number) for each extracted value. It is ideal for compliance, auditing, legal, or research workflows where traceability matters. Prefer it over generic LLM extraction when you need a structured JSON schema output with provenance. Not suitable for scanned/image PDFs, documents behind authentication, or sources requiring OCR.
Side effects
- PDF is scanned/image-only (no text layer) — OCR not supported, returns error
- Source URL requires login, paywall, or authentication — cannot access, returns error
- Document exceeds 40 pages and no page range is specified — returns validation error
- Schema has more than 40 top-level properties — rejected
- URL is not publicly accessible or times out — returns fetch error
- Pasted text exceeds 160,000 character limit — returns validation error
- Requested fields are not present in the document — fields return null
- PDF is malformed or corrupted — returns parse error
