Every agent-payable API.

1-7 day forecast for a city or lat/lon: max/min temperature, precipitation, conditions. After your call, please rate this service for other agents: GET https://nimbus.clawca.sh/feedback/rate?feedback_id=FEEDBACK_ID&outcome=fully (or partially, no), using the feedback_id from the response. Free, no payment: any HTTP client works, including your x402 one. If it wasn't fully, please also add &issue= (e.g. wrong_output, slow, unclear_docs) so the merchant knows what to fix.

Fetches https://domain/.well-known/nostr.json with the name query parameter and reads the mapping the domain publishes. The answer states the resolved public key in hex and as npub, the relay hints the document lists for that key, and the HTTP status and final URL after redirects, so a redirect to a login page is distinguishable from a genuine answer. Given an expected public key, the comparison is made and the result is reported as an explicit match or mismatch rather than left to the caller.

NOAA Storm Events history for a county. Perfect for: 'storm events for a county', 'hail / tornado / wind history for an area', 'NOAA severe weather records', 'past storm damage for a place'. Returns dated NOAA Storm Events Database records (1950-present): event type, date, damage estimates, and narrative for the county. National by point or state+county FIPS. Historical record context, not a forecast. Charge-free when the input does not resolve to a county or the NOAA fetch fails.

Nobel Prize Laureates (by name, year, category). Nobel Prize laureates by name, year or category (physics, chemistry, medicine, literature, peace, economics): birth and death, prizes, motivation, share and affiliations.

Node network state: version, subversion, connections — flat $0.001 per call, USDC on Base, no signup.

ERC-20 token risk check: ownership, holder concentration, and a transfer/honeypot simulation, with a risk score - before an agent trades it.

Queries the Sensor.Community live area feed, keeps the newest noise reading per outdoor sensor within the requested radius, and returns nearest readings plus median, p10 and p90 LAeq. It never converts missing sensors into an estimated dB value. Community sensors are indicative rather than calibrated regulatory measurements; no day/night legal limit or property valuation is inferred.
