Didit ID Verification API

Overview

Verifies an identity document from images (or PDFs) of its front and back in one synchronous call. Classifies the document automatically (you never declare the country or type), reads the visual zone with OCR, decodes the MRZ and barcodes, cross-checks dates, number formats and MRZ check digits, and by default screens both images for screen replays, printed copies and portrait manipulation. Returns the extracted fields, an Approved or Declined status and a warnings list.

Key constraints:

• Formats: JPEG, PNG, WebP, TIFF or PDF (extensions jpg, jpeg, png, webp, tiff, pdf). Encrypted PDFs need front_image_password / back_image_password
• Maximum upload size: 10 MB per side (larger files get 400). Images are compressed server-side
• Send the full, uncropped capture with all four corners visible; the service detects, aligns and crops the document itself
• Send back_image whenever the document has a back: many ID cards carry the MRZ or barcode there, and a missing back leaves those fields empty without a warning

Coverage: 14,000+ document types from 220+ countries and territories: passports, national ID cards, driver's licenses, residence permits and more.

Pricing: $0.20 per call that returns 200 (Approved or Declined); 400 responses are not billed, and standalone calls have no free tier. These are the list prices until 1 November 2026, when Didit pricing changes and the 500 free checks a month become $10 of free credit a month. Check didit.me/pricing for current prices. Digital ID wallets are billed separately (see Digital ID Wallets).

Sandbox: sandbox API keys skip processing and billing and return a static Approved mock (a fictional "Sandbox User" USA identity card) after request validation. Nothing is stored.
