eBird API 2.0 is one of 6 APIs that [Cornell University](https://apis.io/providers/cornell/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Research Data, Citizen Science, Biodiversity, and Ornithology. The published artifact set on APIs.io includes API documentation and authentication docs.

Global bird-observation API run by the Cornell Lab of Ornithology, a unit of Cornell University. Free but token-gated: requests without a valid X-eBirdApiToken return 403. Reference documentation is published as a Postman collection rather than an OpenAPI, so no contract is saved in this repo — a gated surface with no machine-readable contract is recorded as the relationship it is, not as an artifact Cornell published.
