# Didit ID Verification API

## Overview

Verifies identity documents by submitting images of the front and back sides. Performs OCR extraction, MRZ parsing, authenticity checks, and document liveness detection.

**Key constraints:**
- Supported formats: **JPEG, PNG, WebP, TIFF**
- Maximum file size: **5MB** per image
- All document corners must be visible, full-color, no glare/shadows
- Original real-time photos only (no screenshots, scans, or digital copies)

**Coverage:** 4,000+ document types, 220+ countries, 130+ languages. Supports passports, national ID cards, driver's licenses, and residence permits.

**Processing pipeline:**
1. Intelligent capture & document type detection
2. OCR text extraction + MRZ/barcode parsing
3. Template matching, security feature validation, tamper detection
4. Document liveness (detects screen captures, printed copies, portrait manipulation)

**API Reference:** https://docs.didit.me/standalone-apis/id-verification
**Feature Guide:** https://docs.didit.me/core-technology/id-verification/overview
**Supported Documents:** https://docs.didit.me/core-technology/id-verification/supported-documents-id-verification

## Authentication

All requests require `x-api-key` header. Get your key from [Didit Business Console](https://business.didit.me) → API & Webhooks, or via programmatic registration (see below).

## Getting Started (No Account Yet?)

If you don't have a Didit API key, create one in 2 API calls:

1. **Register:** `POST https://apx.didit.me/auth/v2/programmatic/register/` with `{"email": "you@gmail.com", "password": "MyStr0ng!Pass"}`
2. **Check email** for a 6-character OTP code
3. **Verify:** `POST https://apx.didit.me/auth/v2/programmatic/verify-email/` with `{"email": "you@gmail.com", "code": "A3K9F2"}` → response includes `api_key`

**To add credits:** `GET /v3/billing/balance/` to check, `POST /v3/billing/top-up/` with `{"amount_in_dollars": 50}` for a Stripe checkout link.

See the **didit-verification-management** skill for full platform management (workflows, sessions, users, billing).

## Common Workflows

### Basic ID Verification

```
1. POST /v3/id-verification/ → front_image (+ back_image if applicable)
2. If "Approved" → extract first_name, last_name, date_of_birth, document_number
   If "Declined" → check warnings:
     DOCUMENT_EXPIRED → ask for valid document
     SCREEN_CAPTURE_DETECTED → ask for real photo of physical document
     MRZ_VALIDATION_FAILED → ask for clearer image
```

### Full Identity Verification Pipeline

```
1. POST /v3/id-verification/ → verify document
2. POST /v3/passive-liveness/ → verify real person
3. POST /v3/face-match/ → compare selfie to document portrait
4. POST /v3/aml/ → screen extracted name/DOB/nationality
5. All Approved → fully verified identity
```
