## 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 tripguard-fare-intelligence-efbd93f1 -d '<json body>'
```

Example prompt: Check if that $180 round-trip deal from JFK to LAX next month is legit and whether the price is likely to drop further before I book — give me up to 5 results.

## When to prefer this

Choose this endpoint when an AI travel agent needs to verify the legitimacy of a flight deal, predict whether airfare prices will drop before a given travel date, or obtain verified booking links — particularly for consumer-facing booking workflows where fraud detection and price intelligence add value over raw search. Best suited for per-query, real-time lookups rather than bulk fare monitoring.

## Known failure modes

- Query too vague to return relevant airfare results
- No fare data available for an obscure or thin route
- Payment of 0.12 USDC not completed — 402 response returned
- Query string exceeds 512-character limit
- Limit parameter exceeds maximum of 20
- Stale or cached data if live pricing feeds are temporarily unavailable

## How this service works

Real-time airfare intelligence for AI travel-booking agents: flight price-drop prediction, fare-fraud and deal-legitimacy verification, and verified booking links for any route and date. Pay-per-call in USDC on Base. No API key.

## Output

Returns a list of up to 20 search results (default 5), each containing a URL, title, and snippet — representing airfare intelligence items such as price-drop predictions, fare legitimacy assessments, and verified booking links relevant to the queried route or deal.
