Live US tide data for coastal & maritime AI.
A coastal or maritime agent needs current tide state — sourced and citeable. Dynamic Feed serves NOAA CO-OPS tide predictions and observed water levels keyless over MCP or REST, each signed and timestamped.
The call
Keyless over MCP, or one REST call with a free key. Every datapoint is provenance-stamped and citeable.
# Keyless — one signed call over REST:
curl -s https://dynamicfeed.ai/v1/batch -H "Content-Type: application/json" \
-d '{"calls":[{"tool":"tides","args":{"location":"san francisco"}}]}'
# MCP (keyless) — point any client at https://dynamicfeed.ai/mcp, then call tides(location="san francisco")Sample response

Dynamic Feed serves tide data from NOAA CO-OPS (Tides & Currents) — next high/low tide predictions and the latest observed water level, with heights relative to the MLLW datum — for US coastal stations, in a provenance envelope, signed over their exact bytes and verifiable against /.well-known/keys. Next-tide values are predictions (models); the latest water level is an observed measurement. It surfaces what NOAA published at a time — it is data, NOT a substitute for official tide tables or navigation, and not a guarantee of completeness.
Use it for
- Ground a coastal / maritime agent in live US tide state
- A signed record of tide predictions at a point in time
- Port-ops and coastal-planning workflows that need a citeable reading
- Pairs with marine forecast, vessel-tracking and weather feeds
FAQ
What does it cover?
US coastal stations via NOAA CO-OPS — next high/low tide predictions and the latest observed water level (MLLW datum). It does not cover non-US stations.
Is this safe for navigation?
No. Dynamic Feed surfaces public NOAA tide data with provenance and a signature. It is data, not a substitute for official tide tables or navigation — defer to NOAA and official charts.
Predictions or measurements?
Both: next-tide values are predictions (models); the latest water level is an observed measurement. Signing proves the record, not that a prediction is correct.
