Signed maritime evidence, AIS, weather, tides, GPS integrity at sea.
A maritime data layer for agents, robots and developers. One keyless MCP or REST call returns live AIS vessel positions, marine weather, tide stations and GPS integrity at sea as Ed25519-signed, provenance-stamped, archived records, captured as they happen, so any party can re-check them later without trusting your word or ours. Evidence with provenance, not a navigation aid, and not a guarantee of vessel truth.
After the fact, the conditions are un-provable.
When a cargo is damaged, a hull is holed, or a vessel arrives late, the claim turns on what was true at a specific time and place, the sea state, the weather, the tide, and where the vessel actually was. Most of that arrives as self-reported logs or screenshots: a master's note, a weather report pulled days later, an app capture. None of it is independent, and any of it can be questioned.
And an AIS gap, a vessel going dark, is itself a contested fact. Was the transponder off, jammed, or simply out of coverage? After the incident, there's rarely a record anyone can trust to settle it. What holds up is an independent, third-party record, captured at the moment it existed, signed and timestamped, and re-checkable by either party. That's what this vertical provides.
A signed record of conditions anyone can check.
Live maritime conditions, delivered the same way every datapoint we publish is, signed, sourced, and archived.
- Live AIS vessel positions. Our
shipping_statustool returns live AIS vessel positions, names, types and destinations across the Baltic (Digitraffic Finland), by region preset, a third-party record of what was broadcast at a time. - Marine weather & sea state. Our
marine_forecasttool returns wave height, swell, period, direction and sea-surface temperature for a coast, the conditions a dispute later argues over. - Tide stations & buoy observations. Our
tidestool (NOAA CO-OPS) andocean_buoys(NOAA NDBC, ~900 stations reporting) give tide and live buoy readings at a station. - GPS integrity at sea. Our
gps_interferencetool gives a region-level GPS/GNSS-integrity indicator, the signal behind an AIS gap or a wandering fix near a contested coast. Pairs with the GPS-integrity vertical. - 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 an incident.
- 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, vessels under way.
This is a live shipping_status reading, fetched in your browser from POST /v1/batch, live AIS vessel positions in the Baltic (Digitraffic Finland, source updates ~every 30s). The count is the vessels currently reported in the selected region. Pick a region to re-fetch.
30
30 vessels were reporting live AIS positions in this region, names, types and destinations included in the record. Live AIS via Digitraffic Finland (Baltic coverage), captured as a signed, provenance-stamped reading.
AIS is third-party, self-reported vessel data. This is a signed record of what was broadcast and observed at a time, not a guarantee of vessel truth, position accuracy or completeness. A vessel can broadcast a wrong position, or not broadcast at all. It is evidence, not a navigation aid and not a safety guarantee; coverage here is the Baltic.
Teams who need a record that holds up.
An independent underwriting input
When a loss turns on the sea state, the tide, or a vessel's position at a time, an independent third-party reading signed at that moment is a record neither party controls, evidence, not a self-report.
Reconstruct the conditions
Produce a signed, timestamped record of weather, sea state, tide and AIS position for the time and place in question, captured as it happened, re-checkable by either side.
Document an AIS gap
A vessel going dark is a contested fact. A signed record of what was broadcast and observed around that window gives a documented basis to investigate, not just a recollection.
Log the operating picture
Capture signed AIS, tide and marine-weather records for your approaches and basin, archived as they happened, an auditable account of the conditions on a given shift.
Evidence that re-checks
An Ed25519-signed, archived datapoint anyone can independently verify, cryptographic evidence that a reading existed unchanged at a time, useful when conditions or position are later questioned.
Explain a wandering fix
A region-level GPS-integrity indicator alongside the AIS record helps distinguish a jammed or degraded fix near a contested coast from a transponder simply switched off.
One call → a signed record.
Call the feed
One keyless MCP or REST call: shipping_status, marine_forecast, tides, ocean_buoys or gps_interference. No key to get started.
Get the conditions
The response carries the AIS positions, sea state, tide or GPS-integrity reading for your region or station, each with its source and exact measurement 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.
Verify it independently
Either party can re-check the signature on the public verify page, see live coverage on the live map, or use the open-source verifier.
One price, the whole platform.
Maritime 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, on any tier. Want the GNSS-jamming angle on its own? See GPS integrity. Need weather conditions at a site on a date, signed for a claim? See weather evidence. Want your own source wrapped the same way? See done-for-you.
A record, not a certification.
AIS is third-party, self-reported vessel data; marine weather is a model forecast, not a measurement. We provide a signed record of what was broadcast or observed at a time, not a guarantee of vessel truth, position accuracy, or navigation safety. 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 marine forecast or warning. This is an independent, signed record, evidence, not a navigation aid and not a safety guarantee; never the sole basis for any safety-of-life-at-sea decision.
Fully automated. Run by AI, end to end.
