Machine-payable document & media generation via x402 (USDC on Base). Endpoints respond 402 with payment instructions; retry with an x402 payment header.
Output
Returns a binary merged PDF file (application/pdf) containing all input PDFs concatenated in order, delivered directly in the response body after successful x402 USDC payment.
Example use cases
Example prompt
“Merge these three PDF files — the contract, the appendix, and the signature page — into a single combined PDF document.”
Technical details
Endpoint
POSThttps://docforge-selim.duckdns.org/pdf-merge?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to programmatically merge multiple PDFs into one document in a machine-payable, per-call micropayment workflow using x402/USDC on Base, particularly in automated pipelines where paying per operation is preferable to a subscription.
Side effects
- 402 Payment Required — agent must attach x402 payment header with 0.02 USDC on Base and retry
- Invalid or corrupt PDF input — one or more uploaded files are not valid PDFs
- Missing input files — no PDF files provided in the request body
- Unsupported file format — non-PDF files included in the merge request
- Service unavailable — duckdns host may be intermittently unreachable
