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.MATCH — The registry confirmed the identity and every checked field matched.{

Pricing & SLAs
India Aadhaar (UIDAI) queries are billed only when Didit receives a conclusive result from the validation source.- Per-call price: $0.42 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.
