PDFops
Hosted PDF API for AI agents, n8n and Python
SubscriptionMCP50 impressionslaunches Apr 18
PDFops is a hosted HTTP API for the PDF work that keeps getting reinvented: fill AcroForm fields, merge documents, inspect a form's fields, generate invoices.
No headless Chromium and no native dependencies, so it runs anywhere a fetch call does: Vercel, Cloudflare Workers, Lambda, Deno Deploy, Bun. Fills are byte-deterministic: same input, same bytes, which is what makes them testable in CI.
Agents get an MCP server (npx -y pdfops-mcp, or the hosted endpoint at https://pdfops.dev/api/mcp), n8n has a verified community node, Python has pip install pdfops, and there is a typed zero-dependency SDK.
Free to try: 100 requests/IP/month keyless, or a free API key (250 requests/month, no card) from pdfops.dev/pricing. Inspect any PDF's form fields in the browser playground without signing up.
PDFops provides a hosted HTTP API to fill, merge, inspect and generate PDFs without native dependencies.

- Zero-dependency SDKs — Typed, zero-dependency SDKs for Python, Node.js and JavaScript simplify integration.
- No-code options — Browser playground, free invoice generator, field inspector and email-based fill service require no code.
- Byte-deterministic fills — Identical input PDFs always produce identical byte output, enabling reliable CI testing.
- Hard-cap quota model — Each plan enforces a strict request limit with HTTP 429 on overage, preventing surprise charges.
