How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=SLV" \
  -F "services=slv_dui" \
  -F "document_number=111111111" \
  -F "date_of_birth=1990-01-01"

Every successful call returns HTTP 200. The outcome_code field tells you what actually happened — distinguishing, for example, a real biometric mismatch (BIOMETRIC_NO_MATCH) from a selfie that could not be read (BIOMETRIC_IMAGE_UNUSABLE). The status shown is the default feature status; your configured Partial Match / No Match actions can override it.

​
Returned data

The exact fields surfaced in source_data depend on what the registry returns. The generated example for slv_dui currently documents this normalized shape:
  • full_name
  • identification_number

​
Pricing & SLAs

El Salvador - DUI verification queries are billed only when Didit receives a conclusive result from the validation source.
  • Per-call price: $0.20 USD.
  • Billing: per successful query. You are not charged when the registry is unreachable, when required fields are missing, or when the request is rejected before reaching the source.
  • Latency: typical p95 < 2 s.
  • Availability: 99.9% per quarter on Didit’s side; downstream source availability varies by country and dataset.
