Get branch AI Gateway endpoint

API Reference / AI Gateway / Get branch AI Gateway endpoint

Returns the AI Gateway endpoint host for the specified branch, used to render code-snippet base URLs. A 200 response means the branch is registered and this region serves the AI gateway. A 404 response includes a reason field indicating why the gateway is unavailable.

Note: This endpoint is currently in Beta.

• project_id (string, path, required) The Neon project ID
• branch_id (string, path, required) The Neon branch ID

404 AI Gateway is not available for this branch, or the project/branch was not found. The body is always BranchAiGatewayNotEnabled — see reason for the exact cause.

• code (string, required)

• message (string, required)

• reason (string, required) Machine-readable reason why the AI gateway is unavailable:

  • ai_gateway_unavailable: the project's region/cell has no AI gateway configured.
  • branch_not_found: the project or branch does not exist, or the caller does not have access to it.

  Possible values: ai_gateway_unavailable, branch_not_found

default General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received.

• If no response is returned from the API, a network error or timeout likely occurred.
• In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: POST, PATCH, DELETE, and PUT. Retrying these methods is generally not safe. The following methods are considered idempotent: GET, HEAD, and OPTIONS. Retrying these methods is safe in the event of a network error or timeout.

Any request that returns a 503 Service Unavailable response is always safe to retry.

Any request that returns a 423 Locked response is safe to retry. 423 Locked indicates that the resource is temporarily locked, for example, due to another operation in progress.

• request_id (string, optional) Unique identifier for the request, useful for debugging. You can set this value manually by including an X-Request-ID header in the request. If not provided, the value will be generated automatically.

• code (string, required) Machine-readable code classifying the error type. See message for a human-readable explanation. Default: ``

• message (string, required) Error message
