Responses

objectBranchAiGateway

base_urlstring · urirequired

The AI-gateway endpoint root for this branch — an OpenAI-compatible base URL. No dialect path is included; clients append the route (e.g. `/ai-gateway/openai/v1/responses`) themselves.

enabledbooleanrequired

Always `true` in 200 responses. Present for forward compatibility, mirroring BranchStorage.enabled.

Example response

{
  "base_url": "https://br-cool-moon-42-api.ai.c-2.local.neon.build",
  "enabled": true
}

objectBranchAiGatewayNotEnabled

codestringrequired

messagestringrequired

reasonstringrequired

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.

defaultGeneral 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. application/json
