AIS Fleet
Get 7 days of tide predictions for any point (lat, lon; optional start=YYYY-MM-DD, default today UTC) as JSON: high and low water times and heights and hourly heights, above chart datum where known. The nearest tide station within 10 nm answers, otherwise a global tide model, named with its distance; tidal current slack and strongest flood and ebb where a current station is within 5 nm. Astronomical tide only, no surge.

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.

Using Roundhouse, look up the x402 service AIS Fleet 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=AIS%20Fleet' 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://aisfleet.com/api/x402/v1/tides/predictions, 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. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
