What it does

Search the catalog of every cataloged Earth-orbiting object — ~69,000 satellites, rocket bodies, and debris tracked by US Space Force / 18 SDS (via CelesTrak SATCAT). Filter by name (q, e.g. "starlink"), owner/launching country (owner — code like US/PRC/CIS or a name like "china"), object type (type = payload | rocket body | debris | unknown), launch-year range (launchYearFrom/launchYearTo), international/COSPAR designator prefix (intlDesignator, e.g. "2024-"), on-orbit vs decayed (onOrbit), or exact NORAD number (noradId). Each result carries the NORAD id, name, international designator, object type, owner + resolved country, launch date + site, decay date (null = still in orbit), and orbital parameters (period, inclination, apogee, perigee). The envelope total is the full count matching your filter — so onOrbit=true&type=payload answers "how many active satellites are up there", and owner=PRC tells you who launched them. For a satellite's live sub-point position, pass its noradId to /api/space/satellite.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/57351.json for the price and payment options.
Pay. Call GET https://2s-rjsw718bb-alleyford.vercel.app/api/space/satellites. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base Sepolia, Solana, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
