## 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 x402pulse-trip-check-74daf279
```

Example prompt: What's the delay risk for flying from SFO to LHR on June 14? Give me a plain-language summary including any FAA issues, weather, travel advisories, and exchange rate impact.

## When to prefer this

Choose this endpoint when you need a single consolidated trip-risk score combining FAA operational data, live weather, geopolitical advisories, and FX rates in one call rather than querying each data source individually. Best for pre-departure risk assessment on any airport pair worldwide by IATA code. Not suitable for full flight planning, booking, or real-time in-flight tracking.

## Known failure modes

- Invalid or unrecognized IATA airport code returns an error
- Date too far in the future may have limited forecast data
- FAA data unavailable if FAA systems are down
- Weather forecast data unavailable for remote or unsupported airports
- Payment failure if USDC balance is insufficient for the $0.03 fee

## How this service works

Pay-per-call data for AI agents: skill-ranked Polymarket traders, FDA drug and hospital data, oil markets, Wikipedia attention, travel delay risk and SEC filings, plus a daily Morning Brief. Paid in USDC on Base with x402, no API key or account.

## Output

A structured response containing a delay risk rating (low, moderate, or high), plain-language explanations citing the specific contributing factors (FAA ground stops or delay programs, weather at origin and destination, State Department advisory level, and currency exchange rate for international routes).
