How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.
Output
An array of up to 14 12-hour forecast periods for the requested location, each containing weather condition details such as temperature, precipitation probability, wind, and sky conditions, drawn from the US National Weather Service grid.
Example use cases
Trip planning weather check
“Can you get me the next 10 forecast periods for 742 Evergreen Terrace, Springfield, IL so I know what conditions to expect?”
Coordinate-based forecast lookup
“Fetch me 14 periods of weather forecast data for latitude 40.7128, longitude -74.0060 — I need the full two weeks.”
Single-day event weather check
“What are the next 2 forecast periods at 1600 Pennsylvania Ave NW, Washington, DC 20500? I just need today's outlook.”
Technical details
Endpoint
POSThttps://chain.tollkit.dev/weather?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need US weather forecast data and want to pay per-call without creating an account or managing API keys — ideal for agent workflows where credential management is undesirable and crypto micropayments (USDC on Base or Solana via x402) are available. Prefer it over traditional weather APIs when you want frictionless, accountless access.
Side effects
- Location outside the US NWS coverage area returns an error (NWS only covers US territories)
- Invalid or unresolvable street address causes geocoding failure
- Lat/lon or address missing from request body results in a 400-level error
- Payment not provided or insufficient USDC causes x402 payment-required rejection
- Periods value exceeding 14 is rejected by schema validation
