## 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 climatepulse-date-pick-outdoor-event-date-ranker-cfef4882
```

Example prompt: I'm planning an outdoor wedding and need to pick between May 10, May 17, May 24, and May 31, 2025 near Austin, Texas — can you rank those dates by historical weather odds and tell me which one to book?

## When to prefer this

Use this endpoint when a user needs to choose between specific calendar dates for an outdoor event and wants the decision grounded in multi-year historical climate odds rather than a short-range forecast. Ideal for weddings, festivals, races, graduations, and any event booked weeks or months in advance where future forecasts are unavailable. Prefer this over a simple forecast API when comparing multiple candidate dates or when the event date is more than 10 days out.

## Known failure modes

- Fewer than 2 or more than 6 candidate dates provided — returns validation error
- Invalid or unrecognizable location — returns geocoding error
- Dates outside the 10-year historical reanalysis window — insufficient data error
- Network timeout fetching NASA POWER data — 504 response
- Payment not completed or insufficient USDC — 402 Payment Required

## How this service works

Rank 2-6 candidate dates for an outdoor event by real historical weather odds. Rain, heat, frost, wind, and extreme-heat probabilities counted in code from 10 years of NASA POWER reanalysis rows for each date, a deterministic 0-100 weather-favorability score, per-date risk verdicts, and a plain-language recommendation. The "which Saturday should we book?" call for weddings, festivals, and races — any location worldwide.

## Output

Returns a ranked list of the candidate dates each with a deterministic 0–100 weather-favorability score, per-date probabilities for rain, heat, frost, wind, and extreme heat derived from 10 years of NASA POWER reanalysis data, a risk verdict label per date, and a plain-language recommendation identifying the best booking choice.
