How this service works
Merge 2-10 PDFs into one, in order. Deterministic, 0.003/call. Returns the merged PDF base64-encoded.
Output
A base64-encoded string representing the merged PDF file, produced deterministically by concatenating the supplied PDFs in the order given. The agent can decode this string to obtain the final PDF binary.
Example use cases
Assembling a multi-part contract
“I have a contract split into three separate PDFs — the main agreement at https://docs.example.com/agreement.pdf, the schedule at https://docs.example.com/schedule.pdf, and the signature page at https://docs.example.com/signatures.pdf. Can you merge them into one PDF in that order?”
Combining monthly invoices for accounting
“Combine these five invoice PDFs into a single file for our accountant: https://billing.example.com/jan.pdf, https://billing.example.com/feb.pdf, https://billing.example.com/mar.pdf, https://billing.example.com/apr.pdf, https://billing.example.com/may.pdf — keep them in that order.”
Building a presentation packet from chapters
“I've got four separate chapter PDFs for a report I need to hand out — https://files.example.com/ch1.pdf, https://files.example.com/ch2.pdf, https://files.example.com/ch3.pdf, and https://files.example.com/ch4.pdf. Please merge them into one complete document.”
Technical details
Endpoint
POSThttps://mart402.com/v1/pdf-merge?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, deterministic, low-cost PDF merge from a list of publicly accessible PDF URLs with no additional transformation. It is ideal for automation pipelines that need to combine documents programmatically without user interaction. Prefer it over heavier document-processing services when you only need ordered concatenation and want a predictable per-call cost.
Side effects
- One or more URLs is unreachable or returns a non-PDF content type — API returns an error
- More than 10 URLs supplied — exceeds maximum input limit
- Fewer than 2 URLs supplied — minimum not met
- A source PDF is password-protected or corrupted — processing fails
- Payment of 0.003 USDC via x402 not completed — request rejected
