Example use cases
Combine monthly financial reports
“I have three monthly financial report PDFs at https://reports.example.com/jan.pdf, https://reports.example.com/feb.pdf, and https://reports.example.com/mar.pdf — can you merge them into a single quarterly PDF and give me the base64 output?”

Technical details
Endpoint
POSThttps://api.vextorium.com/v1/pdf-merge?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically merge multiple remote PDF files into a single document without setting up your own PDF processing infrastructure. Ideal for AI agents handling document automation workflows where PDFs are available at public URLs and the merged result is needed as base64 for further processing or storage. Pay-per-call pricing at $0.004 USDC makes it cost-effective for occasional or variable-volume merges.
Side effects
- Invalid or inaccessible PDF URLs return an error
- Non-PDF URLs or URLs returning non-PDF content cause merge failure
- Empty URLs array results in a validation error
- Network timeouts fetching remote PDFs
- Corrupted or password-protected PDFs may fail to merge
