@pondlog/source-inaturalist

iNaturalist API client. Typed, Zod-validated, rate-limited, returns Result<T> instead of throwing. Part of pondlog.

No API key required. iNaturalist reads are open. The library handles the 100 req/min rate limit internally and backs off on 429.

Install

npm install @pondlog/source-inaturalist @pondlog/core

Example

import { getNearbyObservations } from "@pondlog/source-inaturalist";

const result = await getNearbyObservations(
  { lat: 48.118, lng: -123.4307 }, // Port Angeles, WA
  25,                               // km
  7,                                // days
);

if (!result.ok) {
  console.error(result.error.message);
  process.exit(1);
}

for (const obs of result.data) {
  console.log(obs.commonName, obs.taxonName, obs.observedAt);
}
