https://x402-seller.onrender.com/water/flood-risk

Shares a payout wallet with 22 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Flood risk at a US river gauge: current water level measured against the official National Weather Service flood stages (action, minor, moderate, major), how many feet remain before each one is reached, and NOAA's own observed and forecast flood category. Answers "is this river near flooding". Takes a USGS site number or an NWS gauge ID. Not every gauge has official flood stages.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
23

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

Latency
not yet measured

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
2

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 52% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 23 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.
