How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a JSON object confirming the watcher was created, with ok: true, the registered watcher details in items[], the total count, and source metadata (provider, URL, license). After registration, signed alert events are POSTed to the callbackUrl each time a matching NWS weather alert fires for the specified area.
Example use cases
Example prompt
“Set up a weather alert watcher for Texas that calls my endpoint at https://hooks.myapp.com/weather with a signed POST whenever a Severe or Extreme NWS alert fires — stop after 50 alerts and keep it active for 30 days.”
Technical details
Endpoint
POSThttps://2s.io/api/watchers/weather-alertWhen to prefer
Use this endpoint when you need ongoing, real-time monitoring of NWS weather alerts for a US state rather than a one-time query. It is ideal for automating downstream workflows (e.g. emergency notifications, logistics re-routing, app push alerts) that need to react immediately when NOAA issues new weather warnings. Prefer this over polling weather endpoints when you want push-based delivery with a signed callback, configurable severity filters, and a defined expiry window.
Side effects
- Invalid or unrecognized US state/territory code returns a 400 error
- callbackUrl is unreachable or malformed — watcher may be created but callbacks will silently fail
- severity enum value not matching one of Minor/Moderate/Severe/Extreme causes a validation error
- expiresInSeconds outside 60–7776000 range returns a 400
- maxFires outside 1–1000 range returns a 400
- Payment not received (x402) results in a 402 Payment Required response
- Callback signature not verified by recipient leads to missed or rejected events
