SEC filings and financials, IP lookup, US weather, airport delays, address geocoding and exchange rates. Other Tollkit tools are described at: https://extract.tollkit.dev/openapi.json, https://attest.tollkit.dev/openapi.json, https://web.tollkit.dev/openapi.json, https://chain.tollkit.dev/openapi.json.
A JSON response containing an array of up to 14 sequential 12-hour forecast periods for the requested location, each likely including temperature, precipitation probability, wind speed/direction, and weather condition descriptions. No API key is required; payment is made in-band via x402 protocol in USDC on Base or Solana.
POSThttps://data.tollkit.dev/weather?utm_source=zero.xyzChoose this endpoint when you need a no-signup, pay-per-call weather forecast and want to avoid API key management. It is ideal for AI agents that need weather data on demand for US locations, especially when combined with x402 micropayment infrastructure. It suits one-off or low-volume forecast lookups billed per call rather than a subscription.
