How this service works
Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.
Output
Returns the extracted text and/or structured content from the PDF document at the provided URL. Results are cached per payment hash so retrying after a successful payment does not incur an additional charge.
Example use cases
Example prompt
“Extract all the text from this PDF for me: https://example.com/report.pdf — I need the readable content from it.”
Technical details
Endpoint
GEThttps://x402.wallace.us/x402/pdf-extractWhen to prefer
Choose this endpoint when you need to extract text from a PDF hosted at a public URL and are operating in a Lightning/x402 micropayment environment. Best suited for one-off PDF parsing tasks in a self-hosted personal-assistant context where per-call billing via Lightning is acceptable. Prefer this over heavier document-processing SaaS when low cost and Lightning-native payment flow are priorities.
Side effects
- Invalid or inaccessible PDF URL — document not reachable or returns non-PDF content
- Payment not yet confirmed — HTTP 402 returned with Lightning invoice requiring payment before content is served
- Malformed PDF — document cannot be parsed or is encrypted/password-protected
- URL missing or malformed in request body — schema validation error
- Payment hash not recognized — retry with wrong or missing X-Payment-Hash header
