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

Profile a confirmed exoplanetary system by host-star name (e.g. "TRAPPIST-1", "Kepler-90", "TOI-700"). Groups all the star's known planets into one view, summarizes the host star (spectral type, temperature, radius, mass, distance in light-years), and COMPUTES the star's habitable ("Goldilocks") zone — inner and outer boundary in AU, derived from the stellar luminosity (effective temperature + radius vs. the Sun) — then flags which planets orbit within it. Each planet: radius/mass (Earth units), orbital period, semi-major axis, equilibrium temperature, and in-habitable-zone flag. Astronomy, habitability research, education. Built from the NASA Exoplanet Archive (the same data as /api/space/exoplanet) plus the computed HZ. Public-domain NASA data.

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.

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.
