# RIPE Atlas anchor mesh measurements

`GET /api/v1/network/atlas/anchor/measurements`

## Request

- Base URL: `https://sugra.ai`
- URL: `https://sugra.ai/api/v1/network/atlas/anchor/measurements`
- Auth: API key in header `x-api-key`

List anchor mesh measurements with uniform limit/offset pagination. The RIPE Atlas anchor-measurements API has no server-side field filtering, so each row carries parsed target_anchor_id / measurement_id for client-side narrowing; complete server-side anchor/type filtering is a planned follow-up (pre-warmed catalog).

## Query parameters

- `limit` integer
- `offset` integer: 0-based offset into the anchor-measurement catalog.

## Response `200`

## Other responses

- `401`: Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422`: Validation Error
- `429`: Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `500`: This API answered a shape its own schema refuses. Typed body `error: response_shape_invalid`. Stays a 500. Not an upstream failure.
- `503`: Upstream source is temporarily unavailable. Retry after a short delay.
