Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/earthquake/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Search earthquakes

Query the USGS earthquake catalog. Returns seismic events matching the given time range, magnitude bounds, and optional geographic bounding box. Results are ordered by the chosen sort and paginated via offset. Each event includes its ID, magnitude, place description, coordinates (longitude, latitude, depth in km), occurrence time (epoch ms), last-updated time (epoch ms), review status, and USGS detail URL.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `endtime` | string | Yes | End of the time window, ISO format YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS. |
| `limit` | integer | No | Maximum number of events to return (1–20000). |
| `max_latitude` | string | No | Northern boundary of bounding box, decimal degrees [-90, 90]. |
| `max_longitude` | string | No | Eastern boundary of bounding box, decimal degrees [-360, 360]. |
| `max_magnitude` | string | No | Maximum magnitude filter (e.g. '7.0'). Omitting applies no upper bound. |
| `min_latitude` | string | No | Southern boundary of bounding box, decimal degrees [-90, 90]. |
| `min_longitude` | string | No | Western boundary of bounding box, decimal degrees [-360, 360]. |
| `min_magnitude` | string | No | Minimum magnitude filter (e.g. '2.5'). Omitting returns all magnitudes. |
| `offset` | integer | No | 1-based offset for pagination. First page is offset=1. |
| `orderby` | string | No | Sort order for results. |
| `starttime` | string | Yes | Start of the time window, ISO format YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS. |
