War-Tracker Vessel Track

Recent AIS position polyline for one vessel by IMO. Response shape: `{imo, hours_requested, hours_effective, raw_points_in_window, downsample_step, points: [{captured_utc, lat, lon, sog, cog}, …]}` — ordered oldest-first so a client can plot the track without sorting. The `?hours=` parameter is currently clamped to 1 (anything wider is silently rolled back — the param stays in the route signature so we can ship longer windows as higher-priced tiers without a rename).

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.

Show the prompt
Using Roundhouse, look up the x402 service War-Tracker Vessel Track 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%20Track'
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/9368223/track, 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.
