Example prompt: Pull me up to 50 newly registered interstate carriers from Texas in the last 14 days that are authorized for hire and check their authority, insurance, and safety status before I tender any loads to them.

## When to prefer this

Use this endpoint when you need to quickly vet multiple newly registered FMCSA trucking carriers in bulk before tendering freight, especially when filtering by state, cargo type, hazmat authorization, or for-hire status. Prefer this over manual FMCSA portal lookups when automating carrier onboarding or compliance workflows in an agent pipeline.

## Known failure modes

- Invalid state code returns empty or error response
- days parameter outside 1-90 range may return error
- limit parameter outside 1-200 range may be rejected
- No carriers matching filters returns empty list
- Payment failure (x402) blocks access to results
- FMCSA data source unavailable causes upstream error
