Registry code: a5267338eb6bbb59

Use the earthquake_* tools to query seismic data from USGS ComCat and the EMSC SeismicPortal; no API key required. earthquake_get_feed gives USGS real-time magnitude tiers for current activity; earthquake_search handles historical or filtered queries, sized first with earthquake_count (search caps at 20,000 events). Both emit network-specific event IDs (e.g. us6000sznj) for earthquake_get_event, which returns full USGS detail (EMSC has no per-event endpoint). USGS carries richer metadata (PAGER, DYFI, ShakeMap); source=emsc is an independent global catalog from the European-Mediterranean…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

earthquake_get_feed unknown never probed

Fetch a USGS pre-computed real-time earthquake feed by magnitude tier and time window. These feeds are CDN-cached by USGS and faster and more available than the query API — use them for "what's happening now" queries. "all" includes microseisms (M<1); "significant" is a USGS curation based on magnitude, felt reports, and PAGER impact estimates. "hour" returns 0–10 events typically; "month" can exceed 10,000 for the "all" tier, so results are returned a page at a time: count is the page size, totalCount the whole feed, and nextCursor the input for the following page. The cursor is opaque and must be passed back verbatim — unlike earthquake_search, these feeds have no upstream paging parameter and USGS regenerates them about once a minute, so a numeric offset across two calls would skip or repeat events. For historical or filtered queries, use earthquake_search instead.

earthquake_search unknown never probed

Search earthquakes by time range, magnitude, depth, location radius, PAGER alert level, or felt reports. Supports USGS (global, richer metadata: PAGER, DYFI, ShakeMap) and EMSC, an independent global catalog operated by the European-Mediterranean Seismological Centre. For location-based queries, provide latitude, longitude, and radius_km together. A rectangular study area is expressed with min_latitude, max_latitude, min_longitude, and max_longitude — each independently optional, so a single edge is a valid constraint. Combining the box with the lat/lon/radius circle intersects the two, returning only events inside both. Both catalogs include non-tectonic records (quarry blasts, explosions) — every event carries its event_type, and event_type="earthquake" filters the rest out on USGS. USGS-specific filters (alert_level, event_type, min_felt, min_significance) are not sent when source=emsc — the response names them in ignoredFilters. Use earthquake_count first to gauge result size before requesting large result sets. A single call returns at most 20,000 events; larger result sets are retrieved by paging with offset, which is passed straight through to the upstream FDSN API. When a result is capped, nextOffset carries the offset for the following page and totalCount the full match count — or countUnavailable reports that the count lookup failed and the total is unknown.

earthquake_get_event unknown never probed
Fetch detail for a specific earthquake by USGS event ID. Returns the same normalized event a search result carries, plus a projection of the analysis products only the single-event response holds: PAGER impact alert and report link, ShakeMap peak intensity and ground motion, DYFI felt-report totals, the moment-tensor focal mechanism, landslide and liquefaction alerts, origin quality (azimuthal gap, station count, location uncertainty), and finite-fault rupture dimensions. Products are omitted when USGS produced none — a small automatic event typically has no detail at all, while a large reviewed one has most of it. Event IDs appear in the "id" field of earthquake_get_feed and earthquake_search results. This tool is USGS-only — EMSC events have no per-event detail endpoint.

earthquake_count unknown never probed

Count earthquakes matching filters without fetching full records. Use for statistical queries ("how many M5+ earthquakes in 2025?") or to gauge result size before calling earthquake_search. Omitting start_time counts only the last 30 days, so pass an explicit range for any period-specific question; queryEcho reports the window and filters the count actually covers. When exceeds_limit is true, the count exceeds 20,000 and a full search would be truncated — narrow filters before fetching. USGS returns the max_allowed cap (20,000); EMSC count endpoint does not return this field (max_allowed will be null). Counts can be scoped to a rectangular study area with min_latitude, max_latitude, min_longitude, and max_longitude — each independently optional. Combining the box with the lat/lon/radius circle intersects the two, counting only events inside both. Both catalogs include non-tectonic records, so a radius over a mining region counts quarry blasts alongside earthquakes — pass event_type="earthquake" on USGS to exclude them. USGS-specific filters (alert_level, event_type, min_felt, min_significance) are not sent when source=emsc — the response names them in ignoredFilters.
