# Search identities

POST https://app.resemble.ai/api/v2/identity/search
Content-Type: application/json

Search the team's identities (plus global identities) for matches against a media sample. Supports audio (voice matching) and image (face/visual matching); video is not yet supported for synchronous search.


Reference: https://docs.resemble.ai/api-reference/identity/search-identities

## Authentication

- `Authorization` header (bearer token, required) — API key from https://app.resemble.ai/hub/api

## Request

### Body (application/json)

This endpoint expects an object.

- `url` (string, optional) — URL to the media sample (one of url, file, signed_id is required)
- `signed_id` (string, optional) — Signed ID from a secure upload
- `modality` (enum, optional) — Inferred from the media's content type when omitted (defaults to audio)
  - Allowed values: `audio`, `image`
- `top_k` (integer, optional, default: 1)

## Response

### 200

Search results

- `success` (boolean, optional)
- `modality` (enum, optional)
  - Allowed values: `audio`, `image`
- `item` (map from string to IdentitySearchPostResponsesContentApplicationJsonSchemaItem, optional) — Matches keyed by identity UUID. distance is a 0-100 match score (higher is closer; an identical sample scores 100). Image matches include score_type "cosine".

## Errors

### 400 Bad Request Error

Search failed

- `success` (boolean, optional)
- `error` (string, optional)
- `errors` (map from string to list of string, optional)
- `message` (string, optional)

### 422 Unprocessable Entity Error

Missing media or unsupported modality

- `success` (boolean, optional)
- `error` (string, optional)
- `errors` (map from string to list of string, optional)
- `message` (string, optional)

## Types

### IdentitySearchPostResponsesContentApplicationJsonSchemaItem

- `name` (string, optional)
- `distance` (double, optional)
- `score_type` (string, optional)
