PDFops

About the startup

Fill, merge and inspect PDF forms from an AI agent, an n8n workflow or Python. PDFops is a hosted API for filling, merging and inspecting PDF forms. You call it from an AI agent over MCP, from an n8n node, from Python, or with plain HTTP. The hard part of PDF forms is rarely writing the values. It is knowing what to write. inspect returns every field name, type and character limit in a document, so you can fill a government blank you have never opened before without guessing at field names. It also handles the cases that break most libraries. Government forms that ship AES-encrypted with an empty user password, which pdf-lib refuses to load. Hybrid AcroForm/XFA files where the XFA layer drops on save. OCR-generated forms whose fields carry no appearance streams and stay invisible until clicked. Free tier is 250 calls a month with no card. There is a public registry of real government forms with measured fill results for each one, so you can check how a specific form behaves before you build against it.
