# fleetfax > fleetfax is free, instant carrier vetting for freight brokers, factors, shippers, and underwriters. It reads the public FMCSA record for every US motor carrier and freight broker, its own ingestion of 29 federal datasets, and surfaces one plain carrier profile: operating authority, insurance on file, safety data versus peers, observed fleet and operating area, and discrete risk findings. fleetfax is descriptive, not prescriptive: it surfaces the federal facts as findings and summarizes them in one descriptive line; it never gives booking advice and never reduces a carrier to a safety, risk, or quality score. Observed is not booked, absence is not proof, and self-reported is not verified. ## Developers - [Carrier Risk Profile schema](https://www.fleetfax.com/schema/carrier-risk-profile-v1.json): Versioned JSON Schema (draft 2020-12) for the carrier profile fleetfax returns: identity, authority, insurance, findings with stable reason codes, and the descriptive verdict state. ## Product - [Carrier report](https://www.fleetfax.com/): Search any USDOT or MC number and read the full carrier report, free. - [Vet a carrier](https://www.fleetfax.com/vet): What is in a fleetfax carrier report and how to read it. - [Pricing](https://www.fleetfax.com/pricing): The full report is free forever; every account gets a book that is read against the federal record every day and the alerts it produces. fleetfax Pro adds a bigger book, same-day alerts on every carrier in it, the dated change timeline, and bulk vetting. ## Learn - [Methodology](https://www.fleetfax.com/methodology): How fleetfax reads the FMCSA record, derives findings, and phrases the descriptive verdict. - [Glossary](https://www.fleetfax.com/glossary): Plain definitions of carrier, authority, insurance, and safety terms. - [FAQ](https://www.fleetfax.com/faq): Common questions about carrier vetting and the fleetfax record. - [Research](https://www.fleetfax.com/research/): fleetfax analyses of the federal data, chameleon carriers, the new-authority washout, and the Motus feed cutover. ## For AI assistants fleetfax welcomes AI crawlers.
