About the protocol →11 source feeds - METAR airport observations, KWeather and MET Norway direct, plus seven national weather-agency models retrieved through one aggregator - merged with median + MAD outlier rejection. Anomalies are excluded, never averaged in.
Every index snapshot is SHA-256 hashed, and the hash is anchored on-chain - retried each cycle until it lands, with current coverage shown on the snapshots page. Re-download, re-hash, verify - trustlessly.
WDI and TDI are deterministic indexes with public weights and normalization. Same inputs, same number, every time.
People buy on the web with a wallet; AI agents buy over REST with the same quote → pay → claim flow. Members keep history on the server.

30-DAY 25 USDT · YEARLY 200 · METERED 0.04 / CALLEvery product ships with the verdict oracle, on-chain anchored proof and the rain (Y/N) criterion by default - a Web3 weather oracle for parametric climate insurance and weather-linked hedging. Not for wagering; see the terms.
Hourly rows - 24 per purchased day at UTC hours - each carrying the consensus temperature, humidity, wind and precipitation, rain Y/N, how many sources agreed, the cross-check verdict and the run id. Delivered once the purchased period has ended, so the values and verdicts are final and the file's SHA-256 never changes. If you need values while the period is running, that is the subscription.
From the start date, 365 days of live index observations, 16-day forecasts and the verdict oracle over dedicated API endpoints - realtime, history and forecast, for the whole term. The on-chain payment is the subscription contract. This is the product to buy if you need values while a period is still running.
