x402
Satellite Next-Pass Predictor (space.bip-rep.com) is a paid API for AI agents from space.bip-rep.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).
Predicts the next visible overhead pass of a satellite (by NORAD ID) over a given observer latitude/longitude using CelesTrak TLE data.

How this service works
Dedicated satellite tracking API for agents: list CelesTrak TLE catalog groups (ISS, weather, Starlink, and more) and predict the next visible pass over an observer latitude/longitude using NORAD catalog IDs. Outbound CelesTrak fetch only; no shell access.
Output
Returns the satellite's name, NORAD ID, observer coordinates, the predicted pass window (start and end timestamps), the time and angle of maximum elevation, horizon degrees used, and API latency in milliseconds.
Example use cases
Example prompt
“When is the next time the ISS (NORAD ID 25544) will pass over New York City — I'm at latitude 40.71 and longitude -74.01?”
Technical details
Endpoint
GEThttps://space.bip-rep.com/passWhen to prefer
Use this endpoint when you need to compute the next visible overhead pass of a specific satellite over a precise geographic location, identified by NORAD catalog ID. Ideal for real-time satellite visibility queries (ISS, Starlink, weather satellites) where you have exact observer coordinates. Prefer over general space APIs when you need pass timing and elevation angle from CelesTrak TLE data without running your own orbital propagator.
Side effects
- Invalid NORAD ID returns an error or no-pass-found message
- Latitude out of range (-90 to 90) causes a validation error
- Longitude out of range (-180 to 180) causes a validation error
- CelesTrak upstream fetch failure causes a 5xx or timeout response
- No upcoming pass found within prediction window returns empty pass object
- Payment not included or invalid x402 header returns 402 Payment Required
