How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=IND" \
  -F "services=ind_epic_voter_s_registration" \
  -F "vendor_data=user-1234" \
  -F "consent=true" \
  -F "full_name=John Doe" \
  -F "date_of_birth=1990-01-01" \
  -F "epic_card=ABC1234567"

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 ind_epic_voter_s_registration currently documents this normalized shape:
  • date_of_birth
  • full_name
  • identification_number

​
Pricing & SLAs

India EPIC (Voter’s Registration) (ECI) queries are billed only when Didit receives a conclusive result from the validation source.
  • Per-call price: $0.84 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.
