How this service works
Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.
Output
Returns a slim JSON object containing an items array of water level or tide prediction records for the requested station and date range, along with a uiLink pointing to the NOAA CO-OPS visualization page for the same query. Each item contains timestamped water level or prediction values.
Example use cases
Boating departure window planning
“What are the predicted high and low tides at NOAA station 8443970 (Boston) for this Saturday and Sunday, using the MLLW datum in English units? I want to know when we can safely leave the harbor.”
Coastal flood monitoring for a city
“Get me the observed water levels for NOAA station 8518750 (The Battery, NY) from 2024-09-27 to 2024-09-28 in metric units with a 6-minute interval — I need to see if there was any surge during that storm.”
Historical tidal research data pull
“Fetch the monthly mean water level data from NOAA CO-OPS station 9414290 (San Francisco) for January through March 2023, NAVD datum, in metric units.”
Technical details
Endpoint
GEThttps://project-api-gamma-sable.vercel.app/paid/noaa/coops?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need NOAA CO-OPS tide and water level data programmatically via a pay-per-call micro-payment API (USDC on Base via x402 protocol) rather than calling NOAA directly. Ideal for AI agents that need structured, slim JSON tidal data without managing NOAA API authentication, and for workflows that want automatic micropayment settlement. Prefer this over scraping NOAA directly when you need reliable structured output with a defined schema.
Side effects
- HTTP 402 Payment Required if USDC payment on Base is not included
- Missing or invalid station ID returns an error or empty items array
- Invalid date format (not YYYY-MM-DD) may cause a query failure
- Unsupported product name or datum string results in an error response
- Station with no data for requested date range returns empty items
- Network or upstream NOAA API outage causes failure
