Signed weather evidence, conditions at a place and time, provable later.
An agent calls one keyless feed and gets back current conditions and multi-model forecasts (globally) and official US severe-weather alerts as Ed25519-signed, provenance-stamped, archived records, captured as they happen, so any agent, adjuster or counterparty can re-verify what the source reported months later without trusting your word or ours. When a claim or dispute turns on the weather at a site on a date, hail, wind, rain, a washed-out event, a frost, a signed record beats a screenshot pulled days later. Evidence of what was reported, not a guarantee of conditions; not a forecast warranty.
After the storm, the conditions are un-provable.
When a roof is damaged, a crop is frosted, a site floods, or an outdoor event is washed out, the claim turns on what was true at a specific time and place, the rain that fell, the wind that gusted, the hail, the temperature. Most of that arrives weeks later as a screenshot of a weather app or a report pulled long after the fact. None of it is independent, and either party can question it, the value being claimed, the date, even whether the conditions happened at all.
What holds up is an independent, third-party record, the conditions a trusted source reported, captured at the moment they existed, signed and timestamped, and re-checkable by either side. Not a recollection, not a screenshot anyone could have edited. That's what this vertical provides: a signed, archived record of what the weather source reported at a place and time.
A signed record of the conditions anyone can check.
Live weather, delivered the same way every datapoint we publish is, signed, sourced, and archived.
- Current conditions, globally. Our
current_weathertool returns temperature, feels-like, humidity, wind speed & direction and precipitation for any lat / lon, an observation/model blend, with its exact observation time. Weather data by Open-Meteo.com. - Multi-model forecasts. Our
weather_forecasttool returns a 7-day forecast with an honest agreement signal across four independent global models (ECMWF, GFS, ICON, GEM), so the record carries the spread, not a single false-precision number. Weather data by Open-Meteo.com. - Official US severe-weather alerts. Our
weather_alertstool returns active US National Weather Service warnings, thunderstorm, flood, flash-flood, marine and more, with the issuing office, area, severity and effective/expiry times. Source: US NOAA/NWS (US coverage). - Signed, sourced & archived. Every reading is Ed25519-signed over its exact bytes, carries its source / URL / measurement timestamp, and is written to an append-only signed archive, so it can't be quietly rewritten after a loss.
- An honest uncertainty signal. A forecast is a model prediction; the consensus across independent models tells you how much to trust each day, far-out days carry lower confidence, an honesty a single-site app can't give you.
- Verify it yourself. A public verify page and the open-source verifier let either party re-check a signature independently, in their own code, without trusting us.
Right now, at a location.
This is a live current_weather reading, fetched in your browser from POST /v1/batch, current conditions at the selected location (Weather data by Open-Meteo.com). The number is the temperature reported at the observation time. Pick a city to re-fetch.
16.1°C
Overcast · wind 11.4 km/h · humidity 77%. The conditions Open-Meteo reported at this location, captured as a signed, provenance-stamped reading.
This is a signed record of what the source reported at a time, current conditions are an observation/model blend, and a forecast is a model prediction. It is evidence of what was reported, not a guarantee that the weather was or will be as stated, and not a forecast warranty. Severe-weather alerts are US-only (NOAA/NWS); current conditions and forecasts are global (Open-Meteo).
Teams who need a record that holds up.
Reconstruct the conditions
Produce a signed, timestamped record of the conditions a source reported for the time and place in question, captured as it happened, re-checkable by either side instead of a screenshot.
An independent claims input
When a hail, wind or storm claim turns on the conditions at a site on a date, an independent third-party reading signed at that time is a record neither party controls, evidence, not a self-report.
Document a frost or washout
A signed record of temperature, rainfall and conditions over a growing site, captured as it happened, gives parametric and indemnity claims a documented, re-checkable basis.
Log the season's conditions
Capture signed current-conditions and forecast records over your blocks, archived as they happened, an auditable account of the weather a crop was grown through.
Substantiate a cancellation
When an event is called off or washed out, a signed record of the conditions and any active warning gives organisers and insurers documented evidence, not a memory of the day.
Record stand-down conditions
Log the conditions behind a weather stand-down, a delay claim, or a site decision, signed and timestamped at the moment, archived as a re-checkable record.
One call → a signed record.
Call the feed
One keyless MCP or REST call: current_weather or weather_forecast with a lat / lon, or weather_alerts for active US warnings. No key to get started.
Get the conditions
The response carries the current conditions, the multi-model forecast, or the active alerts for your location, each with its source and exact measurement/observation time.
Keep the signed record
Every response is Ed25519-signed and provenance-stamped, and written to the append-only archive, so you can produce it months later for a claim.
Verify it independently
Either party can re-check the signature on the public verify page or with the open-source verifier, no need to trust us.
One price, the whole platform.
Weather evidence is part of Dynamic Feed, not a separate bill. Start free and keyless; paid tiers (Builder, Scale, Enterprise) are in early access — request access and tell us your workload. The same signed, sourced, archived records on every tier.
Every tier is self-serve, even Enterprise. Mint a key and you are live in seconds, no call required. Need marine weather, tides and AIS at sea? See the maritime vertical. Need the GNSS-jamming angle? See GPS integrity. Need point-in-time security evidence, known-exploited CVEs and TLS certs, signed for an audit? See security evidence. Want your own source wrapped the same way? See done-for-you.
A record, not a certification.
A forecast is a model prediction; current conditions are an observation/model blend. We sign a record of what the source reported at a time, not a guarantee that the weather was or will be as stated, and not a forecast warranty. Signing and anchoring prove that a datapoint existed, unchanged, at a specific time, they do not prove it is true or accurate; we make no accuracy guarantees about the upstream source, and this is not an official weather forecast or warning service. Coverage: current conditions and forecasts are global via Open-Meteo; severe-weather alerts are US-only via NOAA/NWS. This is an independent, signed record, evidence of what was reported, not a safety certification. Weather data by Open-Meteo.com; severe-weather alerts source: US NOAA/NWS.
