The service's listing describes it this way: Use this when you need to know whether a US motor carrier's biennial MCS-150 update is due or overdue. For 1 to 10 USDOT numbers: next and last filing deadline (49 CFR 390.19T), days left in the carrier's state time zone, overdue flag, USDOT status, and deactivation enforcement: the FMCSA suspended it for updates due since 2026-06-01 and is unclear on earlier ones (notice, quote and read date returned). No personal data. Not a consumer report under the FCRA. Website

How we count Biennial Update Sentinel
A service is a tool an AI agent pays to call. Biennial Update Sentinel is listed on this page settling on Base, through x402. 30-day settled volume on this page is $0.41. The listing comes from the service catalog. Open a row for payments, payers, and chains. See [Bazaar](/glossary/bazaar), [agent payment use cases](/learn/agent-payment-use-cases), and the [methodology](/methodology).
We read settlements directly from each chain's public records and refresh them every few minutes.
Data through 2026-11-14. Source: public settlement logs.
Payers can be counted more than once when they paid through more than one facilitator. Weekly change compares the last 7 full days with the 7 days before, once both weeks are fully covered on this service's networks; other periods compare with the previous period of the same length.
