Shares a payout wallet with 105 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Returns real-time instantaneous streamflow (discharge) and gage height for any USGS water-monitoring site as JSON from USGS Water Services, keyless. Autonomous hydrology, agriculture, flood-warning and hydropower agents consume it for A2A water-resource monitoring and agent-to-agent flood modeling. Ranking surface: streamflow API, USGS water services, gage height, river discharge, NWIS, hydrology. Pay-per-call via x402 on Base. No charge on upstream failure.

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
97

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
42

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

Activity
0

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.

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.
