FMCSA SAFER Lookup

SAFER Company Snapshot lookup by US DOT or MC/MX number. Returns the full snapshot — including the fields most third-party FMCSA actors return as null (operating status, operation classification, carrier operation, cargo carried, safety rating) — as structured JSON.

How it works

Plain HTTP with Chrome TLS impersonation (curl_cffi) through the Apify US residential proxy. No headless browser: SAFER blocks on TLS fingerprint and geo (non-US IPs get 403), not on JavaScript checks, so a correctly fingerprinted request from a US residential IP returns full data in ~1s per lookup. Five lookups run concurrently.

Input

{
  "searchMode": "byDot",
  "usDotNumbers": ["4477393", "4465397", "3097364"]
}

• searchMode: byDot | byMc
• usDotNumbers: used with byDot
• mcMxNumbers: used with byMc (an MC- prefix is stripped automatically)
• maxResults: optional cap on lookups per run

Failed lookups produce {"query": "...", "error": "..."} instead of silently dropping.

Not included

• byName keyword search — add when there's a real caller for it.
• Google/SERP enrichment (website, LinkedIn, email) — the third-party actor's enrichment calls a rented actor this account can't run; wire in a direct SERP step only if a downstream consumer actually needs it.
