Before your agent pays a new bank account: validate the IBAN (all countries), resolve its bank and BIC from national bank registries, and check SEPA reachability per scheme (SCT, SCT Inst, SDD Core/B2B) against the EPC register

Check whether a company can receive e-invoices on the Peppol network before you send one: participant identifiers and accepted document types from the official Peppol Directory export, by SIREN, SIRET or explicit Peppol participant ID. 'Not registered' is a paid, dated answer. No account, no key.

Before your agent buys, lists or insures a vehicle: decode any 17-character VIN offline — manufacturer, country and region of build, model year, check digit validity and deterministic attributes from the official NHTSA vPIC tables

Before your agent verifies a 'hotter than normal' claim, reports climate exposure or settles an anomaly-based trigger: how far observed temperature, precipitation and wind departed from the WMO 1991-2020 climatological normal, for any GPS point or city over a date range within the rolling ~5-year Copernicus ERA5 window.

Before your agent pays an IBAN taken from OCR or invoice ingestion: fix a broken or garbled IBAN — recompute check digits, recover unreadable characters (?) and rank candidates by known bank from national bank registries

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 (rolling ~5-year window), with the served grid cell and a coverage flag.

Before your agent sizes heating or cooling demand, settles an energy contract or models crop growth: heating, cooling and growing degree-days (HDD/CDD/GDD) for any GPS point or city over a date range, computed from Copernicus ERA5 daily mean temperature (rolling ~5-year window) with the NWS/EIA/WMO mean-temperature method.

Before your agent stores or messages a phone number: validate and normalize it offline — E.164 formatting, region, national format and line type from Google's libphonenumber metadata, no network call

Before your agent buys, sells or services a vehicle: list manufacturer recall campaigns that may affect it, consolidated from official NHTSA and RappelConso sources, matched by make, model and year or from a VIN. An empty list means no known recall

Validate any EU VAT number live against the official European Commission VIES service before you invoice cross-border, or derive and check the French VAT number from a SIREN. Returns valid/invalid or an honest 'unverifiable' when the member state is down - syntax check always included. No account, no key.

Before your agent plans a multi-day operation — logistics, construction, an event, crop work: a day-by-day forecast for any GPS point or city, with daily minimum and maximum 2 m temperature, total precipitation and peak 10 m wind per UTC calendar day, from today to the end of the NOAA GFS window (~16 days). Each day names the model that served it and carries a coverage flag.

Full counterparty due-diligence on a French company in one paid call, by SIREN: Sirene identity and status, dated BODACC insolvency/deregistration/sale announcements, live EU VAT validation (VIES) and Peppol e-invoicing reachability - each block with its own provenance. The pre-action check before you invoice, pay or onboard. No account, no key.

Before your agent updates a contract clause or a compliance rule that depends on a law: see exactly what changed in a French or EU article between two dates — resolves the version in force at each date, from the official LEGI and EUR-Lex datasets, and returns a word-level diff plus a git-style unified patch with both versions' metadata. Covers 12 major French codes and statutes and key EU acts (GDPR, DSA, AI Act, MiCA and more).

Before your agent relies on a stored legal citation or watches a provision for change: the full version timeline of a French or EU article — each version's status (in force, repealed, superseded, deferred) and validity dates, from the official LEGI and EUR-Lex datasets — to detect exactly when it changed. 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 schedules a delivery, plans outdoor work or hedges short-term weather exposure: a point forecast of 2 m temperature, precipitation and 10 m wind — plus opt-in convective, humidity, cloud and snow variables — for any GPS point or city. Deterministic NOAA GFS at 0.25 deg to 16 days (384 h), NOAA GEFS ensemble mean at 0.5 deg to 35 days (840 h); the lead selector is optional (omitted, the forecast defaults to the current analysis time) and the response names the model that served it and the exact forecast step.
