How this service works
Global market, government and reference data for AI agents. Pay-per-call over x402 (USDC on Base mainnet).
Output
Returns a JSON object containing weather forecast data for the specified coordinates, including expected conditions over the requested number of days (temperature, precipitation, and other meteorological indicators). The exact schema is open-ended but covers multi-day outlook information.
Example use cases
Trip planning weather check
“Can you pull a 7-day weather forecast for latitude 48.8566, longitude 2.3522 — I'm planning activities in Paris next week and want to know what conditions to expect.”
Outdoor event weather lookup
“What's the 3-day weather forecast for coordinates 51.5074, -0.1278? I'm organizing an outdoor event in London and need to know if it'll rain.”
Agricultural field conditions forecast
“Get me a 10-day weather forecast for lat 41.8781, lon -87.6298 — we're tracking conditions for crop planning near Chicago.”

Endpoint
GEThttps://worlddata402.worlddata402.workers.dev/v1/weather/forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call weather forecast with no subscription or API key — useful for agents that call weather infrequently or need to pay programmatically via USDC on Base. Best when you have precise lat/lon coordinates and want a simple, lightweight forecast lookup without committing to a monthly weather data plan.
Side effects
- Missing required lat or lon parameter returns an error
- Invalid coordinate values (out of range lat/lon) may return no data or an error
- Payment failure via x402/USDC returns a 402 Payment Required response
- Very remote or ocean coordinates may return limited or no forecast data
- Requesting too many days beyond supported range may return partial results or an error
