How this service works
Fit-to-haul verdict for a US motor carrier from FMCSA registration data. Give one of dot, mc or name and get a verdict (fit, caution, unfit or not_found), a 0-100 fit score, per-dimension flags, reasons and weighted signals across authority status, operation, hazmat, safety rating, history, registration freshness, address and fleet. Deterministic, no LLM. Carrier vetting indicators, not legal or compliance advice.
Output
Returns a fit-to-haul verdict (fit, caution, unfit, or not_found), a 0–100 numeric fit score, per-dimension flags, human-readable reasons, and weighted signals covering authority status, operation type, hazmat certification, safety rating, history, registration freshness, address, and fleet size. Deterministic, no LLM involved.
Example use cases
Example prompt
“Can you vet carrier 'Acme Freight LLC' for me — pull their FMCSA fitness score and check if they're cleared for general haul? Their DOT number is 3456789.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/freight/carrier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, structured fitness assessment of a US motor carrier before booking freight, onboarding a new carrier, or auditing a carrier relationship. Prefer this over manual FMCSA portal lookups or LLM-based assessments when you need a scored, multi-dimensional verdict with flags and reasons rather than raw data. Best suited for freight brokers, shippers, or logistics platforms automating carrier vetting workflows.
Side effects
- Carrier not found in FMCSA data — returns not_found verdict
- Ambiguous carrier name with no state hint — best match used but may be incorrect
- Invalid or malformed DOT/MC number — query parameter error
- Missing required lookup identifier (no dot, mc, or name provided) — 400-level error
- Stale FMCSA data if registration has not been recently refreshed — noted in freshness signals
