How this service works

The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.

Output

Returns the target year's seasonal climate value ranked within the ERA5 historical distribution for the location: a percentile (0–100), an empirical return period in years, and the sample size (number of historical seasons used). Useful for parametric insurance triggers, climate risk reports, and finance applications.

Example use cases

Example prompt

“For Paris (lat 48.85, lon 2.35), what percentile and return period was the 2022 summer mean temperature compared to ERA5 historical climate — and how many years of data is the estimate based on?”

Endpoint

When to prefer

Use this endpoint when you need to quantify how extreme a specific year's season was relative to long-term ERA5 climate history at a location — particularly for parametric insurance triggers, reinsurance pricing, climate risk disclosure, or climate finance. Prefer this over anomaly endpoints when you need return-period framing (e.g. '1-in-20-year event') rather than just deviation from mean. No account or API key needed; pay per call via stablecoin.

Side effects

Invalid or out-of-range coordinates return an error (e.g. lat/lon outside ERA5 coverage)
Unsupported season or variable type returns a validation error
Target year outside ERA5 historical range returns no data
Payment not settled via x402 results in 402 Payment Required response
Missing required query parameters return a 400 Bad Request
