§ Combine and divide
Merge PDF API
Post two or more PDFs and get one document back, in the order you sent them. Twenty files in a request is still one call, and the page count never moves the price.

- Inputs
- 2 to 20 PDFs
- Returns
- application/pdf
- Limits
- 20 MB per file, 60 MB per request, 20 files, 3,000 pages.
- Price
- $0.001
§ 01 The request
One POST, and the file comes back.
POST /pdf/merge
curl -sS --fail-with-body \
-o merged.pdf \

Worth knowing
Sending one file is 400 input_count. pdfcpu cannot read encrypted sources when merging, so protected inputs are decrypted in memory, merged, and re-protected — still without touching disk.
Your first /pdf/merge call takes one line of curl.
Ten thousand calls cost ten dollars, the pack never expires, and nothing you send is kept.
10,000 calls for $10. No subscription, no expiry.
