# aye.today Daylight Hours Check

> aye.today Daylight Hours Check is a paid API for AI agents from aye-booth.aye-today.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a signed aye/nay attestation of whether astronomical daylight hours at a covered city (ORL or DEN) will meet a specified minimum threshold (10, 12, or 14 hours) on today or tomorrow.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aye-today-daylight-hours-check-25aa90ad -d '<json body>'
```

Example prompt: Will Denver have at least 12 hours of daylight tomorrow? Give me a signed aye/nay attestation.

## When to prefer this

Choose this endpoint when you need a cryptographically signed, deterministic attestation of daylight sufficiency — not just a raw data lookup — for Orlando or Denver. Ideal for automated workflows, smart contracts, or agent pipelines that require a verifiable aye/nay receipt rather than raw solar data. Prefer this over general astronomy APIs when auditability and claim provenance matter.

## Known failure modes

- Unsupported place code (only ORL and DEN are covered) returns an error
- Invalid or unsupported min_hours value (only 10, 12, 14 accepted) returns validation error
- Invalid day value (only 'today' or 'tomorrow' accepted) returns error
- Payment failure or insufficient USDC balance results in 402 rejection
- Network or worker availability issues may return 5xx errors

## How this service works

Attested resolution: will astronomical day length at a covered place meet a minimum-hours bar today or tomorrow? Computed-deterministic tier — pure celestial math, zero upstream license exposure. Deterministic per UTC day; same inputs, same claim hash. Delivered as a signed result capped by an aye/nay receipt.

## Output

A signed aye/nay receipt indicating whether the astronomical day length at the specified city meets the minimum-hours threshold on the requested day. The result includes a deterministic claim hash tied to UTC day and inputs, enabling verifiable attestation with zero upstream license exposure.
