## Authentication

Send your API key in the `x-api-key` header on every request. No key yet? Sign up at https://dashboard.bavest.co/sign-up (free trial). The examples read the key from the `BAVEST_API_KEY` environment variable.

## Parameters

None.

## Response

200 Successful response (`application/json`).

| Field | Type | Always present | Description |
|---|---|---|---|
| `data` | object | no |  |
| `data.apiKey` | string | no | API Gateway key identifier. Example: `ut4lshj85e`. |
| `data.usage` | integer | no | API calls used in current billing period. Example: `4521`. |
| `data.limit` | integer \| null | no | Monthly request limit (null if unlimited) Example: `100000`. |
| `data.remaining` | integer \| null | no | Remaining API calls (null if unlimited) Example: `95479`. |
| `data.period` | string | no | Current billing period (YYYY-MM) Example: `2026-03`. |
| `meta` | ResponseMeta | no | Response envelope metadata. Always present on a 200: `time` is set by `core/response.py` on every successful response. Errors carry the same block, built by the same code, so a client parses one meta shape whether the call succeeded or failed. |
| `meta.time` | integer | no | Server-side processing time in milliseconds. Example: `17`. |
| `meta.parameters` | object | no | Echo of the request parameters the endpoint resolved. |

- `403` from the gateway: the API key is invalid or switched off.
- `429` with message `Limit Exceeded`: the monthly quota of the key is used up. With `Too Many Requests`: the key is throttled, or this route is not in the key's plan. Wait for `Retry-After` when it is sent.
