{"jsonrpc":"2.0","id":1,"method":"tools/list"}search_observations — Search citizen-science wildlife observations on iNaturalist — ANY organism: plants, fungi, insects, birds, mammals, reptiles, amphibians. This is the tool for "sightings/observations of <species> in <place> in <year>". Filter by taxon name (scientific or common, e.g. "Leucanthemum vulgare"/"oxeye daisy", "Pandion haliaetus"/"osprey"), place name ("Yukon", "California"), year, threatened status, or quality grade. Returns photographed sightings with coordinates, dates, and observer info. Pairs well with GBIF for cross-validation.search_taxa — Search iNaturalist taxa by name (common or scientific). Returns taxon ID, rank, ancestry, conservation status, and photo URL. Use the taxon ID for downstream filters or to disambiguate look-alike species.top_species — Most-frequently-observed species in a place over a date range. Auto-resolves place name to place_id. Returns ranked species with observation counts and taxonomic info. Great for "what wildlife lives here?" questions.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
