# Build and version metadata

`GET /v1/meta`

## Request

- Base URL: `https://api.hyperresearch.ai`
- URL: `https://api.hyperresearch.ai/v1/meta`
- Auth: none required

Unauthenticated release identity. `engine_version` and `hyperresearch` come from the deploy vars when they carry a real value, and otherwise from the versions this build was compiled against — they are never reported as unknown (E2E2-35). `build_sha` still depends on its deploy var.

## Response `200`

Metadata

- Meta
  - `api_version` string, required
  - `engine_version` string, required
  - `hyperresearch` string, required
  - `contract_version` string, required
  - `environment` string, required
  - `build_sha` string, required
  - `time` string, required
  - `features` object, required: Deployment feature switches a client may branch on.
    - `sharpen_mode` boolean, required: True where the console checks a question before it runs (Sharpen).
