## How to call it through Zero

```sh
zero fetch --capability synapse-flight-search-f4dec8e2
```

Example prompt: Can you pull live flight data right now and show me the current positions, altitudes, and speeds of any aircraft in the air?

## When to prefer this

Choose this endpoint when you need pay-per-call live flight tracking data with no account or API key setup, billed in USDC on Base via x402 protocol. Ideal for agents needing lightweight, on-demand aviation data without committing to a subscription.

## Known failure modes

- No flights returned if no aircraft match query parameters
- Payment failure if USDC balance on Base is insufficient for the $0.002 per-call fee
- Stale or missing data if upstream aviation feed is unavailable
- Empty flights array during low-traffic periods or if query scope is too narrow

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with a Unix timestamp, a count of flights found, and an array of flight objects each containing callsign, latitude, longitude, altitude in meters, velocity in m/s, and origin country.
