Example prompt: Before I tender this load, can you pull the FMCSA carrier authority and safety record for MC number 123456 and flag any issues?

## When to prefer this

Use this endpoint when a freight broker, dispatcher, or logistics agent needs an authoritative, real-time FMCSA federal record for a US motor carrier prior to load tender or carrier onboarding. Prefer this over manual FMCSA portal lookups or scraping when you need structured, agent-consumable carrier authority and safety data with pre-computed risk flags.

## Known failure modes

- MC or DOT number not found in FMCSA database — returns not-found error
- Neither mc nor dot query parameter provided — returns validation error
- FMCSA data source temporarily unavailable — may return service error
- Invalid or malformed MC/DOT number format — returns error

## How this service works

US carrier authority & safety check (FMCSA). Live federal FMCSA record for a US motor carrier: legal name, operating status (allowed to operate), authority, safety rating, fleet size, crash and inspection summary — with plain risk flags. The check a freight-broker or dispatch agent runs before tendering a load.

## Output

Returns the carrier's legal name, current operating status, authority type, safety rating, fleet size, crash summary, inspection summary, and plain-language risk flags derived from the live FMCSA federal record.
