ISS Location API (Open Notify)

aid: iss-api
url: https://raw.githubusercontent.com/api-evangelist/iss-api/refs/heads/main/apis.yml
name: ISS Location API (Open Notify)
kind: API
description: Open Notify is a free, open-source project by Nathan Bergey that exposes real-time NASA and ISS data as simple
  REST endpoints. The service provides the current latitude and longitude of the International Space Station (updated every
  five seconds as the ISS travels at roughly 28,000 km/h), a count and roster of all humans currently in space across all
  spacecraft, and historical ISS pass-time predictions for any point on Earth. All endpoints are unauthenticated, return JSON,
  and are free to use without registration. The ISS pass-time prediction endpoint has been retired; the location and astronaut
  endpoints remain live and operational.
