## 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`):

```

Example prompt: Before I accept this load from broker MC-483920, can you check whether they have active FMCSA broker authority, any bond lapses, and whether their authority has ever been revoked or suspended?

## When to prefer this

Use this endpoint when you need to specifically verify freight broker authority status, bond continuity, or authority history from FMCSA records. Prefer this over general carrier lookup (lookup_carrier) when the entity in question is a broker rather than a carrier, or when bond and authority history details are required. Use when you have either an MC number or a USDOT number for the broker.

## Known failure modes

- MC number not found — broker does not exist in FMCSA database
- Invalid MC or USDOT number format — returns error
- Both mc_number and usdot_number provided — only one should be given
- Broker resolves but holds no broker authority — still billed, returns record showing no authority
- FMCSA data source temporarily unavailable — service may return an error or stale data

## How this service works

Use this to check a freight broker before you accept a load or extend credit: whether it holds active broker authority, its broker dockets and how current each status is, its bond (BMC-84/85) continuity and lapses, its authority history (grants, revocations, suspensions, reinstatements) and the identity linkage screen. Give an MC number or a USDOT number. A record, not a recommendation. Billed whenever the broker resolves, including when it holds no broker authority.

## Output

Returns a structured record containing: active/inactive broker authority status, all broker docket numbers and their current statuses, bond (BMC-84/BMC-85) details including any lapses or gaps, a chronological authority history (grants, revocations, suspensions, reinstatements), and identity linkage screening results. This is a factual record, not a recommendation. Billed even when the broker holds no broker authority.
