Shares a payout wallet with 441 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

One call → what's notable in YOUR sky right now, for a lat/lon. Synthesizes three sources: (1) the live almanac — sun up/down, moon phase + illumination, and which of the 7 naked-eye planets are currently above your horizon with their altitude/azimuth/magnitude; (2) near-Earth asteroid close approaches over the next 7 days (designation, date, distance in lunar distances); and (3) the ISS — its current sub-point, and whether it is above your horizon right now with look angles. Each section reports found/error independently. The "is it dark, what's up, anything passing" digest for stargazers and astrophotographers. For the raw almanac alone see /api/space/sky-tonight.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
61

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
1

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

See the scoring methodology for exactly how each number is computed.

This payout wallet is shared: figures cover all 442 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
