What did the space environment say at decision time? Signed.
Conjunction screening and maneuver calls are made on data that changes hourly: the geomagnetic and radiation environment that drives atmospheric drag, and the catalog position of the object you are flying. After a close approach or an anomaly, the review turns on what was actually known when the decision was made. This page returns a signed, independently re-verifiable snapshot of what the space weather feed and the satellite catalog reported at this moment, and every reading Dynamic Feed serves is archived, so what the record said at time T stays re-checkable. A neutral, timestamped record for the operations log, the insurance file and the licensing file.
The space environment and catalog, right now.
Enter a NORAD catalog id for the object you want the context for. Dynamic Feed records the live space weather from NOAA SWPC and the current SGP4-propagated catalog position for that object, and returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you.

Maneuver decisions are reviewed on records.
When a close approach is worked, or an anomaly is investigated after the fact, the question is rarely what the operator intended; it is what the data showed at the moment the call was made. The geomagnetic and radiation environment drives atmospheric drag and the radiation risk to the platform, and it changes on the scale of hours. The catalog position is propagated from an element set that is itself dated. Screenshots of a dashboard do not survive scrutiny. A contemporaneous record from an independent witness, signed at the moment, carrying its source and observation time, and verifiable years later against a published key, is the kind of corroboration a review board, an underwriter or a regulator can check. Our records work for the operator and the counterparty alike: anyone can re-verify them, including the other side.
Evidence, not a collision-risk determination.
Dynamic Feed is a neutral witness, not a conjunction assessment provider, insurer, regulator or adviser. This record captures the space environment and a single catalog position; it is not a conjunction data message, does not compute a probability of collision, a miss distance or a maneuver recommendation, and the propagated position carries the uncertainty of a public element set. It is a live-now record: it captures what was reported at the moment you request it, not a reconstruction of a past epoch. Coverage, licensing obligations and screening standards vary by operator, jurisdiction and mission. This is advisory evidence for a review, insurance or licensing file, tamper-evident not tamper-proof, zero personal data, and not legal advice.

One API call per decision.
Operations platforms can mint a signed environment-and-catalog record the moment a screening or maneuver decision is logged, keyless to try, self-serve to scale.
