Look up any asteroid or comet in NASA JPL's Small-Body Database by designation, number, or name (e.g. "433", "Eros", "433 Eros", "1P/Halley", "2024 YR4"). Returns full name + kind + orbit class (e.g. Amor, Apollo, Jupiter-family comet), NEO and potentially-hazardous-asteroid flags, physical params (absolute magnitude H, diameter, extent, rotation period, albedo, density, spectral type), and orbital elements (eccentricity, semi-major axis, perihelion/aphelion, inclination, period, Earth MOID, observation arc). Astronomy, planetary-defense, and mission-planning research. Public-domain NASA/JPL data; for a body's near-Earth close approaches see /api/space/close-approaches.
/api/space/bodyPAYMENT-SIGNATURE.The body API is a pay-per-call space endpoint built for AI agents and autonomous software. Look up any asteroid or comet in NASA JPL's Small-Body Database by designation, number, or name (e.g.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in body data source for an agent tool-use loop, an MCP host, or a backend that needs space data on demand without onboarding to yet another vendor portal.
