Single vessel identity by IMO. Returns scalar identity: name, MMSI, flag (ISO-3166-1 alpha-2), AIS type (e.g. `Tanker`, `Cargo`, `Fishing`), subtype (e.g. `Crude Oil Tanker`), commercial market (13-value enum: `WET BULK`, `DRY BULK`, `CONTAINER SHIPS`, …), overall length in metres, year built, and the boolean `sanctioned` / `watchlisted` rollups across OFAC, FCDO, EU, UANI, ASO, GAC, UN, SECO, MFAT, and the War-Tracker OSINT shadow-fleet watchlist. Free for browsers, AI-search crawlers…

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
No per-endpoint history for this service yet, so this is payments indexed to its PROVIDER's wallet over 30 days. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service War-Tracker Vessel Identity and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=War-Tracker%20Vessel%20Identity' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://war-tracker.com/api/v1/vessels/9281554, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
