NASA operates public information and data services, including astronomy, imagery, and technology-project datasets. Its API portal provides developer access to selected public NASA data feeds and services.
NASA exposes public developer-facing HTTP APIs via api.nasa.gov, including the APOD API authenticated with an `api_key` query parameter and a public TechPort API documented by a curated OpenAPI spec; no GraphQL, MCP, or CLI surfaces were verified.
