How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object with a 'fields' property containing key-value pairs of all metadata embedded in the PDF, such as Title, Author, Subject, Creator, Producer, CreationDate, and ModDate, all as string values.
Example use cases
Audit PDF document authorship
“I have a PDF contract and I need to know who authored it and when it was created — can you extract the metadata from the file?”
Catalog uploaded research papers
“For this uploaded research paper PDF, grab all the embedded metadata fields like title, author, subject, and creation date so I can add them to my database.”
Verify PDF provenance before sharing
“Before I share this PDF externally, can you check what metadata is baked into it — I want to see the producer, creator tool, and any dates stored in the file properties?”
Technical details
Endpoint
POSThttps://api.geekvault.dev/docs-tools/v1/pdf-metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast extraction of PDF document metadata (author, title, dates, producer) without full text extraction or content parsing. Ideal for cataloging, auditing, or provenance checks where document properties rather than content are the goal. Prefer this over full PDF-to-text pipelines when you only need the header/info fields. Payment is per-call via USDC on Base with no API key setup required.
Side effects
- Malformed or corrupted PDF returns an error — the file must be a valid PDF
- Empty or missing 'file' field in the request body results in a 400-level error
- Non-PDF binary data (e.g. a DOCX or image) may return empty fields or an error
- Very large PDF files may time out or be rejected depending on size limits
- Payment failure via x402 (insufficient USDC balance) blocks the request before processing
