## 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 fmcsa-motor-carrier-lookup-tollbooth-1cec94fe -d '<json body>'
```

Example prompt: Can you pull up the FMCSA compliance record for the carrier with USDOT number 53467 — I need their operating authority, out-of-service status, insurance on file, and safety rating before I dispatch a load to them.

## When to prefer this

Use this endpoint when you need structured FMCSA carrier compliance data programmatically before dispatching freight, onboarding a carrier, or verifying broker authority — specifically when you have a USDOT number, MC/MX/FF docket, or exact company name. Prefer this over manual FMCSA portal lookups when automating carrier screening workflows. Note: this is not an official FMCSA determination; always confirm with FMCSA before dispatch.

## Known failure modes

- No carrier found matching the name, USDOT, or docket — returns empty array with HTTP 200 (still a paid call)
- Partial or DBA company name provided — name field requires exact legal or DBA match, no partial matching
- Invalid docket format — docket must be MC, MX, or FF followed by digits
- Data may be stale for non-Motus records — legacy snapshot frozen 2026-05-14, not real-time FMCSA
- USDOT number out of valid range (1–99999999) — will be rejected by schema validation
- Payment not provided or insufficient — x402 payment required at $0.03 USDC per call

## How this service works

US motor carrier by USDOT, MC/MX/FF docket or exact company name (FMCSA): USDOT status, out-of-service order, operating authority per docket with grant date and source (Motus, else legacy frozen 2026-05-14), BI&PD, cargo and bond required vs on file, insurance policies, BOC-3, fleet size, safety rating. Up to 10 carriers; empty is a paid 200. Not a determination: verify with FMCSA before dispatch.

## Output

Returns up to 10 matching carriers, each with USDOT status, out-of-service order flag, operating authority per docket with grant date and source (Motus or legacy snapshot), BI&PD and cargo insurance required vs. on file, bond status, individual insurance policies, BOC-3 filing status, fleet size, and safety rating. An empty result set is a valid paid 200 response if no match is found.
