Emboss

Emboss is an API that turns blank PDFs into filled, fillable forms without requiring templates or manual field mapping. It solves the problem of automating paperwork by reading a form's structure, detecting every field type including text, dates, checkboxes, radio buttons, and signature fields, then filling them from data or documents. The system verifies its own work and returns a finished PDF with a receipt that records what was decided and on what evidence.

The API offers several capabilities: extraction to make a PDF fillable, context fill to infer answers from documents, standard fill for direct value input, verification to check completeness, and batch fill for processing hundreds of forms from a spreadsheet. It integrates with platforms including Claude, n8n, Zapier, Pipedream, and Make, and accepts context in PDF, DOCX, CSV, JSON, images, and plain text formats. The API is plain REST with no SDK lock-in, and documents are processed ephemerally with encryption in transit and at rest.

Emboss is designed for developers adding form-filling to products, and for teams automating intake, onboarding, applications, and field work. It offers a free monthly allowance with no card required, and pay-per-call pricing with no subscription, contracts, minimums, or per-seat fees.
