## How to call it through Zero

```sh
zero fetch --capability freight-carrier-lookup-68109650
```

Example prompt: Can you look up freight carriers named 'Swift Transportation' in Texas and return up to 5 matches so I can verify the right one for our shipment?

## When to prefer this

Use this endpoint when you need to search for freight carriers by name for compliance (OFAC), billing verification, or rate checks and want micropayment-based access without a subscription. Prefer this over full logistics APIs when you only need lightweight carrier lookup at low cost per call.

## Known failure modes

- No carriers found matching the provided name — returns empty result set
- Invalid state code provided — may return error or unfiltered results
- Limit parameter out of range (must be 1–15) — returns validation error
- Missing required 'name' query parameter — returns error
- Payment not included or insufficient USDC — returns 402 Payment Required

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a success flag and a result object containing one or more freight carrier candidate records matching the name and optional state filter provided.
