## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

zero fetch --capability didit-database-identity-validation-ad0e071a -d '<json body>'
```

Example prompt: Can you verify this person's identity against official databases — first name Juan, last name García, born 1985-04-22, Mexican nationality (MEX), national ID number GARJ850422HDF, using one_by_one validation?

## When to prefer this

Choose this endpoint when you need to validate identity against government or authoritative national databases for individuals from Latin American countries or Spain. It is particularly suited for KYC/AML compliance workflows, fintech onboarding, and cross-border payment verification where official document-backed identity checks are required. It covers a broad set of Latin American nations plus Spain and supports multiple document types.

## Known failure modes

- Unsupported issuing_state — only a fixed set of Latin American and Spanish countries are supported
- Missing required fields for specific countries (e.g. expiration_date required for ESP)
- Invalid ISO 3166-1 alpha-3 nationality or issuing_state code
- Identification number format mismatch for the given country
- No record found for the provided identity data
- Payment failure or insufficient USDC balance (x402 protocol)
- Invalid document_type value provided

## How this service works
