iDigBio vs USGS Earthquake Hazards Program

iDigBio is a keyless REST API exposing more than 150 million digitized natural-history specimen records — pressed plants, pinned insects, fossils, and more — contributed by U.S. museums and herbaria under an NSF-funded national digitization effort. Search and summary endpoints return Darwin Core fields (collector, locality, taxonomic name) as JSON, and the same backend powers iDigBio's public specimen-browsing portal.

The USGS Earthquake Hazards Program's FDSNWS Event Web Service is a keyless REST API for querying the agency's global earthquake catalog by region, time window, magnitude, or depth, returning real-time and historical seismic event data. Requests default to QuakeML XML but can also return GeoJSON, CSV, or KML via a format parameter, and the whole service is free and unauthenticated, run directly by the federal government.
