# Flight Safety Oracle – Drone & Ground Robot Flight-Safety Index

> Flight Safety Oracle – Drone & Ground Robot Flight-Safety Index is a paid API for AI agents from store.cryptotradecalc.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Returns an aviation-grade flight-safety index for drones and ground robots at a given lat/lon, based on wind, visibility, and precipitation thresholds.

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 flight-safety-oracle-drone-ground-robot-flight-safety-index-36aaca2f
```

Example prompt: Can you check the flight safety index for my drone at latitude 37.7749, longitude -122.4194? I need to know if wind, visibility, and precipitation conditions are within aviation-grade safe limits right now.

## When to prefer this

Use this endpoint when you need a structured, go/no-go safety assessment for drone or ground robot outdoor operations based on real-time aviation-grade weather thresholds — particularly when wind speed, precipitation, and visibility are the critical safety variables. Prefer this over a generic weather API when you need a computed safety index rather than raw weather values, or when operating under aviation-regulatory-style safety standards.

## Known failure modes

- Missing lat/lon parameters returns a 400 bad request or empty result
- Coordinates outside supported weather data coverage area may return null or error
- Weather data provider outage may cause stale or unavailable index
- Malformed coordinate strings (non-numeric) cause schema validation errors
- Network timeout or 402 payment failure if USDC balance insufficient

## How this service works

flight-safety-oracle: Drone & Ground Robot Flight-Safety Index using aviation-grade wind, visibility, and precipitation limits

## Output

Returns an aviation-grade flight-safety index indicating whether conditions are safe for drone or ground robot operation at the specified coordinates, incorporating wind speed, visibility levels, and precipitation assessments against established aviation safety thresholds.
