x402.hydratrader.ai

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.
