Didit Database Validation API

Overview

Verifies personal data against the authoritative source for a country (civil registry, tax authority, electoral roll or biometric registry) and returns a per-field comparison, a per-service outcome code and the registry record. Use it to catch synthetic identities and ID numbers that do not belong to the person.

Pricing: per service, from $0.05 (Dominican Republic dom_cedula) to $7.00 per query; most Latin American national ID services are $0.20 (billed once per service the registry answered, including no-match and not-found answers; 400 rejections and services the source never answered are free; 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.

Key constraints:

• issuing_state is ISO 3166-1 alpha-3 (BRA, PER, ARG). Alpha-2 codes (BR) return 400 "Invalid issuing state".
• Each country exposes one or more services (service_id). Without services, exactly one default service runs. Spain, Kenya, Zambia and most non-Latin-American services have no default: name them in services.
• Required fields depend on the selected services. Missing or malformed fields return 400 before any registry call (never billed).
• Send JSON, or multipart/form-data when a service needs a selfie (Argentina arg_renaper, Panama pan_cedula_sib, other biometric services).
• Results per field: full_match, partial_match, no_match. Overall status: Approved, Declined or In Review.
