All projects on Base matching “usgs”

Live USGS river-gauge tick, deterministic. Answers "what is the flow at this gauge right now", "is this river high or low vs this week". Returns the latest streamflow (discharge, cfs) and gage height (ft) for one USGS site plus the 7-day min/max range, reading count, site name and coordinates, straight from USGS instantaneous values. Unknown sites 404 before payment. No LLM, no key, public domain.

GDACS disaster events SEARCH (keyless). POST {alertlevel?}/{eventlist?}/{fromdate?}/{todate?}/{country?}. Uses geteventlist/SEARCH only (MAP returns 400). Unpaid empty → 402; after settle empty/invalid → 400 charged:false. Light adjacency: usgs-landslides / quake lanes (GDACS multi-hazard ≠ USGS landslide/quake feeds).

Returns the latest instantaneous values at a USGS streamgage, together with what makes them readable. A stage of three point four feet means nothing on its own, so each value is placed against the station own record for the requested reference period: the minimum, median and maximum, and the percentile the current reading falls at. The reference period is stated with the comparison, because a perc

Significant earthquakes — search USGS seismic events above an explicit significance-score threshold, with magnitude and provenance but no danger or probability claim.

Deterministic facts-only snapshot for exploration targets: USGS MRDS deposit counts, geochemical anomaly stats, satellite scene availability, World Bank jurisdiction governance score, and GDELT social-license signal — raw numbers, no AI synthesis. Lite-tier preview of /api/prospect/exploration-brief.

Lightweight utility API for agents and operators: DNS lookups, RDAP/WHOIS domain data, HTTP probes, page metadata extraction, cryptographic hashing, JSON validation, scheduled webhooks, and exotic endpoints (Base transaction decode, ENS resolve, USGS earthquakes, cron next-run, TLS certificate report). No shell access; outbound URL tools enforce SSRF protections.

USGS volcano elevated CAP alerts (keyless getCapElevated). POST {alert_level?} or {include_all:true}. Empty {} -> 400 not charged. earthquake/usgs-landslides/eonet/fema/humdata adjacency disclosed.

USGS NWIS instantaneous values (keyless). sites or stateCd (+ parameterCd default discharge 00060) → trimmed IV series.

USGS FDSN landslide events (keyless; eventtype=landslide). POST {starttime?}/{endtime?}/{limit?}. Empty -> 400 not charged. earthquake/fema/eonet/humdata adjacency disclosed.

USGS EPQS point elevation (keyless). POST {lon,lat} and/or {x,y,units?}. Timeout ≤10s. Empty/5xx → 502/404 not charged.

USGS earthquake GeoJSON feed (keyless). Window day|week|month (significant preferred) → quake list.

Query recent USGS earthquake events by lookback window and minimum magnitude and return compact live event state.
