# Drone Delivery Window Optimizer

> Drone Delivery Window Optimizer is a paid API for AI agents from store.cryptotradecalc.com, paid per call via x402, $0.012/call, status unknown (last checked 2026-09-14).

Performs a binary feasibility check for outdoor drone delivery routes based on wind speed, visibility, precipitation intensity, and frost thresholds for a given city.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 drone-delivery-window-optimizer-ab787c80
```

Example prompt: Can you check if weather conditions in Austin right now are safe enough for a drone delivery — specifically wind, visibility, rain, and frost levels?

## When to prefer this

Use this endpoint when you need a single go/no-go decision on whether drone delivery is feasible in a specific city based on real-time weather conditions — particularly when wind, precipitation, visibility, and frost are all relevant safety factors simultaneously. Prefer this over general weather endpoints when you need a pre-computed drone-safety-specific binary output rather than raw meteorological data.

## Known failure modes

- Missing or invalid city name returns an error or empty result
- City not found in weather data source yields no feasibility result
- Upstream weather data unavailable causes service failure
- Payment not processed (402) blocks access to the endpoint

## How this service works

drone-delivery-window: Drone Delivery Window Optimizer – binary feasibility check for outdoor delivery routes based on wind, visibility, rain/snow intensity, and frost thresholds.

## Output

A binary feasibility result indicating whether outdoor drone delivery is viable, along with the underlying weather factors (wind, visibility, precipitation intensity, frost) that determined the outcome for the queried city.
