How this service works
An x402-paid API suite for autonomous agents. The freight operation preserves deterministic U.S. DOT/FMCSA carrier checks. A self-contained rental market snapshot returns available public rent benchmarks, trends, provenance, and optional budget fit from a ZIP code and bedroom count. Other rental operations normalize, deduplicate, search, compare, and analyze rental observations supplied by a caller who is authorized to process them. Zillow Research ZORI, U.S. Census ZCTA geography, and HUD Fair Market Rent data are not represented as unit-level listings or executed lease rents. Unsigned requests receive the x402 challenge before validation. Credential-bearing retries that are invalid or cannot produce the advertised minimum result are rejected before payment verification and settlement and are not charged.
Output
Returns a JSON object with a top-level PASS/FAIL decision, a unique checkId, the carrier's legal name and USDOT, authority status (USDOT active/inactive, property-for-hire status), safety rating, insurance filing status, optional claimed-identity match flags, reason codes explaining the outcome, evidence dataset provenance with timestamps, and a generatedAt timestamp. The schema version is included for compatibility tracking.
Example use cases
Pre-dispatch carrier compliance screen
“Before we assign this load, run a hire check on USDOT 1234567 — make sure their property authority is active, they have a satisfactory safety rating, and their insurance filings are current.”
Broker onboarding carrier verification
“We're onboarding a new carrier who gave us MC-987654 and claims to be 'Swift Transport LLC' out of Dallas, TX — can you verify that against FMCSA records and flag any identity mismatches?”
Fraud detection on a cold-call carrier
“A carrier cold-called us with USDOT 5556789 and a MC number. Before we give them any freight, check if their authority is active, their safety record is clean, and that their name and address match what's on file with FMCSA.”
Technical details
Endpoint
POSThttps://192.3.171.233/v1/us-freight/carrier-hire-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a deterministic, auditable, single-call carrier hire decision backed directly by FMCSA/DOT public records, with configurable policy thresholds (safety rating, insurance, authority, identity match) and evidence provenance. Prefer this over manual FMCSA portal lookups or generic business-verification APIs when you need structured PASS/FAIL output with reason codes, dataset citations, and x402 micropayment billing that only charges on valid, result-producing calls.
Side effects
- Invalid or unrecognized MC/USDOT number returns a rejection before payment is charged
- Source data older than maxSourceAgeHours policy threshold triggers a staleness rejection
- Carrier has UNSATISFACTORY safety rating and blockUnsatisfactorySafetyRating is true — returns FAIL with reason code
- Insurance filings absent when requireInsuranceFiling is true — returns FAIL
- Identity mismatch detected and reviewClaimedIdentityMismatch is true — returns FAIL or REVIEW decision
- USDOT inactive when requireActiveUsdot is true — returns FAIL
- x402 payment challenge returned for unsigned or unauthenticated requests
- Requests that cannot produce the advertised minimum result are rejected before payment settlement
