# Search earthquakes

`GET /api/v1/earthquakes/search`

Search USGS earthquake catalog by location, magnitude, depth, date range, and PAGER alert level. Full historical catalog available.

## Query parameters

- `starttime` string — Start time (YYYY-MM-DD or ISO 8601).
- `endtime` string — End time (YYYY-MM-DD or ISO 8601).
- `minmagnitude` number — Minimum earthquake magnitude.
- `maxmagnitude` number — Maximum earthquake magnitude.
- `latitude` number — Latitude in decimal degrees (-90 to 90).
- `longitude` number — Longitude in decimal degrees (-180 to 180).
- `maxradiuskm` number — Search circle radius in km.
- `mindepth` number — Minimum earthquake depth in km.
- `maxdepth` number — Maximum earthquake depth in km.
- `alertlevel` string — PAGER alert level: green, yellow, orange, red.
- `limit` integer — Maximum number of records to return.
- `orderby` string — Sort criterion (time, time-asc, magnitude, magnitude-asc).

## Response `200`

      - `longitude` number, required — Longitude in decimal degrees.
      - `latitude` number, required — Latitude in decimal degrees.
      - `depth_km` number, required
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
