Endpoints & examples

Everything below is live today and free to try. All responses are JSON with Access-Control-Allow-Origin: *, so they work straight from the browser.

MCP server (for AI agents)

Streamable HTTP MCP endpoint: get_next_launches, get_iss_passes, get_launch_news. Point Claude, ChatGPT or any agent framework at it.

https://gocosmik.com/api/mcp

{ "tools": ["get_next_launches", "get_iss_passes",
           "get_launch_news"] }

Upcoming launches

Live orbital launch schedule (Launch Library 2), soonest first.

curl https://gocosmik.com/api/launches

{ "results": [
    { "name": "Falcon 9 · Starlink Group 10-1",
      "net": "2026-07-23T04:12:00Z",
      "status": { "name": "Go for Launch" } } ] }

ISS passes for a city

Next visible ISS passes (SGP4), 550+ cities by slug or lat/lon via MCP.

curl https://gocosmik.com/api/widget/iss/paris

{ "city": "Paris", "country": "France",
  "next_pass": { "start_utc": "2026-07-22T21:03:11Z",
    "max_elevation_deg": 62, "duration_min": 6,
    "good_viewing_window": true }, "data_ok": true }

Aurora odds for a city

Tonight’s aurora probability from live NOAA SWPC Kp, per city.

curl https://gocosmik.com/api/widget/aurora/tromso

{ "city": "Tromsø", "kp_now": 4,
  "kp_tonight_max": 6, "kp_required": 3,
  "odds": "high" }

Full satellite catalogue

The whole tracked catalogue (CelesTrak TLEs, by group) in one response.

curl https://gocosmik.com/api/catalog

{ "v": 1, "fetchedAt": "2026-07-22T09:00:00Z",
  "groups": { "starlink": "STARLINK-1007\n1 44713U...",
    "gps-ops": "...", "science": "..." } }

Using your API Pro key

Pass your key as a header X-Api-Key: cok_live_… (or ?key=cok_live_…) on any endpoint. Paid responses carry an X-Cosmik-Plan header and drop the attribution requirement.

curl -H "X-Api-Key: cok_live_xxx" \
  https://gocosmik.com/api/widget/iss/paris

Who this is for

News sites embedding a live launch countdown next to coverage · museums and planetariums driving exhibit screens · educational platforms adding real orbital data to lessons · developers building space apps without running their own TLE pipeline · AI products that want a citable live-data source.

Most of what people build with the API already exists as a drop-in: the Discord bot posts launch and pass alerts to a channel, the Home Assistant integration exposes the ISS and aurora as sensors you can automate on, and the satellite widget is one iframe. Full list: integrations.
