SERPRO Datavalid v4 pf-facial — validates CPF (mandatory) against Receita Federal and matches the live selfie (mandatory) against the CNH portrait stored at Senatran. Optionally screens name and date of birth. Didit exposes this service through
POST /v3/database-validation/ so you can verify the submitted data against the authoritative source and receive normalized match results.

How to call it
curl -X POST "https://verification.didit.me/v3/database-validation/" \
-H "x-api-key: YOUR_API_KEY" \
-F "issuing_state=BRA" \
-F "services=bra_cpf_facial" \

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.{

NO_MATCH — The registry returned no match for the submitted data.{

},
"validation": {

}
}
]
}
BIOMETRIC_NO_MATCH — The face-match score was below the acceptance threshold - the selfie is not the same person as the registry photo.{

"source_data": {
"identification_number": "NO_MATCH"
},
"validation": {
"identification_number": "no_match"
}
}
]
}
BIOMETRIC_IMAGE_UNUSABLE — The selfie could not be processed (empty, no face, low quality, or the registry could not read it). Prompt the user to retake the selfie.{
"request_id": "req_01H…",
"status": "In Review",
"issuing_state": "BRA",

"source_data": {

},
"validation": {
"identification_number": "no_match"
}
}
]
}
INCONCLUSIVE — The registry confirmed the CPF (and the name and date of birth you sent), but the face could not be compared: there is no reference photo on file for this CPF, or the selfie could not be used (no face found, wrong image size, low quality, or more than one face). The confirmed fields stay in validation, so match_type reflects them, but the mandatory face check is unresolved, so the check is sent to review. Ask for a new selfie, or fall back to document verification for people with no photo on file.{
