/// TOOLS
51 PDF and document tools, one REST API
Every tool is a REST endpoint. Call it from Make, Zapier, n8n or Airtable with their HTTP step.MakeZapiern8nAirtableGoogle Sheets
Every tool is a single HTTPS endpoint with the same auth, the same signed webhooks, and the same credit ledger. Sandbox keys never bill — copy any curl below and run it against your sandbox key.
11 of the 51 tools — rotate, extract-pages, remove-pages, metadata, pdf-form-fields, pdf-flatten, pdf-info, pdf-reorder, pdf-crop, pdf-linearize, pdf-tag-check — are local page operations that never touch a rendering engine, OCR or AI, so they don't cost credits.
