PDFops is a hosted HTTP API for the PDF work that keeps getting reinvented: fill AcroForm fields, merge documents, 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.
There is an MCP server too (npx pdfops-mcp) so agents can call it over stdio, plus a typed zero-dep SDK and an n8n community node.
Free tier is 250 requests/month with an emailed API key. Inspect any PDF's form fields in the browser playground without signing up.
