# GitLab Ai agent identities API

**Canonical:** https://apis.io/apis/gitlab/gitlab-ai-agent-identities-api/  
**Provider:** GitLab — https://apis.io/providers/gitlab/  
**Base URL:** https://gitlab.com/api/v4  
**Documentation:** https://docs.gitlab.com/api/rest/

GitLab Ai agent identities API is one of 189 APIs that [GitLab](https://apis.io/providers/gitlab/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification. This API exposes 16 JSON Schema definitions. Tagged areas include Ai agent identities. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, authentication docs, an API reference, rate-limit docs, an AsyncAPI specification, and 16 JSON Schemas.

Use this API to register an external agent identity for a project, so that agent sessions can be attributed to a user and a machine. Registration returns the existing record if one already exists, or is rejected if the identity has been revoked. External agents are published through the [AI Catalog](https://docs.gitlab.com/user/duo_agent_platform/ai_catalog/), and act with a [composite identity](https://docs.gitlab.com/user/duo_agent_platform/composite_identity/) that combines a service account with the human user who initiated the request.
