Where is the ISS now

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Current position of the International Space Station: latitude, longitude, altitude, speed and whether it is in daylight (wheretheiss.at). Use for space apps, education bots and sky-watching alerts.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/iss?format=json"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/iss?format=json&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
