How this service works
Attested resolution: did measurable rain fall in a covered precinct during a stated past window? Ships as an evidence bundle — hash-attested NOAA/NWS source payloads under a signed policy manifest — capped by an aye/nay receipt. The evidence bundle is the product; the boolean is the receipt. Refusals, validation errors and coverage gaps are free; FUTURE windows are refused.
Output
An evidence bundle containing: hash-attested NOAA/NWS source payloads, a signed policy manifest, and a final aye/nay boolean receipt indicating whether measurable rain occurred. Refusals and validation errors are returned for unsupported grids or future time windows. The evidence bundle (not just the boolean) is the deliverable product.
Example use cases
Parametric crop insurance rain claim
“I need to verify whether measurable rain fell in NOAA grid 'OUN/53,76' between April 1st 2025 00:00 UTC and April 7th 2025 23:59 UTC — I need the full attested evidence bundle for a crop insurance claim settlement.”
Smart contract weather oracle resolution
“Can you get me a signed NOAA attestation confirming whether it rained in grid 'LWX/96,70' between March 15th 2025 08:00 UTC and March 15th 2025 20:00 UTC? I need the hash-attested payload to resolve a weather derivative contract.”
Event cancellation dispute evidence
“I need cryptographic proof of whether there was measurable rain in NOAA grid 'LOT/74,75' on July 4th 2025 from 12:00 UTC to 22:00 UTC — we had an outdoor event cancelled and need the aye/nay receipt plus evidence bundle for our dispute.”
Technical details
Endpoint
POSThttps://aye-booth.aye-today.workers.dev/v1/rain_checkWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, tamper-evident attestation of historical rain occurrence — not just raw weather data. Ideal for smart contract oracles, parametric insurance adjudication, legal disputes, or any context where an auditable signed evidence bundle matters more than a simple data lookup. Prefer over generic weather APIs when the signed policy manifest and hash-attested source payload are required for downstream trust.
Side effects
- Future time windows refused — only past windows are supported
- Unknown or uncovered NOAA/NWS grid identifiers return a coverage-gap refusal
- Malformed datetime formats in window_start or window_end cause validation errors
- Grid parameter missing or invalid triggers free validation error response
- NOAA/NWS data unavailability for requested window may result in evidence gap refusal
