A daily feed of what changed in orbit: newly catalogued objects, re-entries, status changes and satellites that moved.
Each event names the object, its owner, type and constellation, and carries the evidence behind it, so you can build alerts, charts or a newsroom tip sheet from the JSON. Ask for one day's digest, a stream of events since your last run, or the current catalogue with orbit and owner on every row.
Run it with the default input: 10 catalogue rows.
Who uses it
- Space journalists get a daily list of new objects, re-entries and unexpected orbit changes.
- Analysts chart constellation behaviour, such as orbit-raising campaigns and deorbits, day by day.
- Space situational awareness start-ups build alerts on a ready-made change feed.
Input
| Field | What it does |
|---|---|
mode | snapshot (default, the current catalogue), events or digest |
since | Events or digests since a date, YYYY-MM-DD. Empty means the last 7 days |
sinceLastRun | true returns only events newer than your last run. Best for schedules |
eventType | new_object, decayed, disappeared, status_change, manoeuvre, manoeuvre_summary |
objectType | PAYLOAD, ROCKET BODY, DEBRIS or UNKNOWN |
constellation | e.g. starlink, oneweb, kuiper, qianfan |
maxItems | Caps the rows, and so the cost |
Output
Each event carries event_id, date, type, norad_id, name, object_type,
constellation, confidence and a details object with the evidence. Snapshot rows carry the
orbit (perigee_km, apogee_km, inclination, period_min, regime) plus owner, state
and launch_date. A digest gives one day's object counts, events by type and the top events.

Pricing
Pay per result. See the Pricing tab for current rates; maxItems caps the rows and so the cost. A run that finds nothing charges nothing per item.
FAQ
How often does it update? Daily. Each event says when it was detected.
What does confidence mean? How strong the evidence is: high, medium or low. The
details object shows the numbers behind it.
Can I follow one constellation? Yes. Set constellation and schedule events with
sinceLastRun: true; you pay for each event once.
Every row carries an attribution field; keep it if you republish. Runs record anonymous usage
counts only, never your inputs or results.
