Weather for any coordinate. Current (default): temperature (C), relative humidity (%), wind speed, weather code — real-time. Historical: add start_date & end_date (YYYY-MM-DD, up to 92 days per call, archive lags ~5 days) for hourly history — backtest weather-sensitive strategies (energy, agriculture, logistics). Inputs: lat, lon, start_date?, end_date?. Keyless (Open-Meteo).

Before your agent onboards or pays a counterparty: screen the bank account for sanctions — flags sanctioned banks (BIC) and high-risk jurisdictions against the official OFAC, EU, UN and FATF lists, for KYB/AML compliance

Before your agent signs off a contract review or a due-diligence memo: check that up to 50 legal citations are still in force at a given date in one call — consolidated text, status and validity dates per reference, from the official LEGI (French law) and EUR-Lex (EU law) datasets. Covers 12 major French codes and statutes and key EU acts (GDPR, DSA, AI Act, MiCA and more).

Before your agent advises on EU compliance or cites EU law: check an act or article is in force at a given date, by CELEX or ELI identifier — consolidated text, status and validity dates, from the official EUR-Lex dataset. Covers key EU digital and financial acts (GDPR, DSA, AI Act, MiCA and more).

Before your agent verifies a weather-dependent claim, backtests a parametric trigger or checks what conditions a site or shipment faced: daily 2 m temperature, total precipitation and 10 m wind at any GPS point or city for a past date, from the Copernicus ERA5 reanalysis — temperature and precipitation cover a rolling 30-year window, wind a rolling ~5-year window — with the served grid cell and a coverage flag.
