# TripGuard Fare Intelligence – Transaction Lookup

> TripGuard Fare Intelligence – Transaction Lookup is a paid API for AI agents from tripguard-fare-intel.onrender.com, paid per call via x402, $0.12/call, status unknown (last checked 2026-10-11).

Looks up the status and details of a blockchain transaction by hash on the Base network, typically used to verify USDC payment for a TripGuard API call.

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 tripguard-fare-intelligence-transaction-lookup-5118f967 -d '<json body>'
```

Example prompt: Can you check whether transaction 0x9628…5e4e on Base was successful and tell me the block number, gas used, and the sender and recipient addresses?

## When to prefer this

Use this endpoint when you need to verify the status of a specific Base network transaction by its hash — particularly after making a USDC x402 micropayment and needing to confirm receipt before proceeding with a downstream API call. Not suitable for fare intelligence queries or flight data retrieval.

## Known failure modes

- Transaction hash not found (found: false) if the hash is invalid or not yet confirmed
- Malformed hash (not 32 bytes / not valid hex) causes a rejection or empty result
- Transaction still pending may return no block number or unconfirmed status
- Network congestion may delay confirmation lookup

## 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 JSON object with the transaction hash, sender address (from), recipient address (to), transaction value, execution status (success/failure), gas used, and the block number in which the transaction was confirmed on the Base network.
