Unico IDCloud biometric validation: matches the user's selfie against the face on record for their CPF and returns whether it is the same person, not the same person, or inconclusive. 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.

## Body parameters

<ParamField body="issuing_state" type="string" required default="BRA" placeholder="BRA">
  ISO 3166-1 alpha-3 country code for this database service.

  Example: `BRA`
</ParamField>

<ParamField body="services" type="string" required default="bra_unico_idcloud" placeholder="bra_unico_idcloud">
  Array containing this service ID. Pinning the service keeps the request scoped to this exact database.

  Example: `bra_unico_idcloud`
</ParamField>

<ParamField body="consent" type="boolean" required default="true" placeholder="true">
  Explicit end-user consent for this service.

  Example: `true`
</ParamField>

<ParamField body="tax_number" type="string" required default="11111111111" placeholder="11111111111">
  Tax or fiscal identification number.

  Example: `11111111111`
</ParamField>

<ParamField body="selfie" type="file" required placeholder="@./selfie.jpg">
  Selfie image file to upload for biometric database validation. Accepted formats: JPEG, PNG, or WebP.

  Example: `@./selfie.jpg`
</ParamField>

<ParamField body="first_name" type="string" default="John" placeholder="John">
  Given name to validate.

  Example: `John`
</ParamField>

<ParamField body="last_name" type="string" default="Doe" placeholder="Doe">
  Family name to validate.

  Example: `Doe`
</ParamField>

<ParamField body="full_name" type="string" default="John Doe" placeholder="John Doe">
  Full legal name to validate.

<ParamField body="date_of_birth" type="string" default="1990-01-01" placeholder="1990-01-01">
  Date of birth in `YYYY-MM-DD` format.

  Example: `1990-01-01`
</ParamField>

<ParamField body="vendor_data" type="string" default="user-1234" placeholder="user-1234">
  Your stable user reference for this person, such as your internal user ID. Didit uses it to link standalone checks to the same end user and reduce duplicate-detection noise.

  Example: `user-1234`
</ParamField>

## Input rules & validation notes

* Brazilian CPF (exactly 11 digits)
* `tax_number` must contain digits only; remove spaces, hyphens, and punctuation before sending the request.
* `tax_number` must be exactly 11 characters long.

## How to call it

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://verification.didit.me/v3/database-validation/" \
    -H "x-api-key: YOUR_API_KEY" \
    -F "issuing_state=BRA" \
    -F "services=bra_unico_idcloud" \
    -F "vendor_data=user-1234" \
    -F "consent=true" \
    -F "tax_number=11111111111" \
    -F "selfie=@./selfie.jpg"
  ```
</RequestExample>

<ResponseExample>
  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](/core-technology/database-validation/database-validation-warnings) can override it.

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

  ```json 200 OK — MATCH theme={null}
  {
    "request_id": "req_01H…",
    "status": "Approved",
    "issuing_state": "BRA",
    "match_type": "full_match",
    "validations": [
      {
        "outcome_code": "MATCH",
        "service_id": "bra_unico_idcloud",
        "service_name": "BRA - Unico IDCloud (CPF + selfie)",
        "source_data": {
          "unico_face_match": "yes"
        },
        "validation": {
          "identification_number": "full_match"
        }
      }
    ]
  }
  ```

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

  ```json 200 OK — BIOMETRIC_NO_MATCH theme={null}
  {
    "request_id": "req_01H…",
    "status": "Declined",
    "issuing_state": "BRA",
    "match_type": "no_match",
    "validations": [
      {
        "outcome_code": "BIOMETRIC_NO_MATCH",
        "service_id": "bra_unico_idcloud",
        "service_name": "BRA - Unico IDCloud (CPF + selfie)",
        "source_data": {
          "identification_number": "NO_MATCH"
        },
        "validation": {
          "identification_number": "no_match"
        }
      }
    ]
  }
  ```

  **`INCONCLUSIVE`** — The registry could not determine whether the person matches - the result is genuinely uncertain (they may or may not be in the registry). This is NOT a no-match and NOT a technical image problem; no field is asserted, so match\_type is null and the check is sent to review.

  ```json 200 OK — INCONCLUSIVE theme={null}
  {
    "request_id": "req_01H…",
    "status": "In Review",
    "issuing_state": "BRA",
    "match_type": null,
    "validations": [
      {
        "outcome_code": "INCONCLUSIVE",
        "service_id": "bra_unico_idcloud",
        "service_name": "BRA - Unico IDCloud (CPF + selfie)",
        "source_data": {},
        "validation": {}
      }
    ]
  }
  ```
</ResponseExample>

## Returned data

The exact fields surfaced in `source_data` depend on what the registry returns. The generated example for `bra_unico_idcloud` currently documents this normalized shape:

* `unico_face_match`

## Pricing & SLAs

BRA - Unico IDCloud (CPF + selfie) 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.
