Automate Motus with a workflow
A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.
Registration and authority status check, every company
Build this- Starts
- Every weekday at 7:00
- Step 1
- For each USDOT number you name, get the registration and authority status from the Motus dashboard.
- Step 2
- Keep the registrations and authorities whose status changed since the last run, and stop when none did.
- Step 3
- Email you the list, one section per company.
New Motus notifications, posted to your team
Build this- Starts

- Step 1
- For each USDOT number, look the company up in Search for Companies.
- Step 2
- Keep the legal name, DBA name and company information shown.
- Step 3
- Post the results to your webhook, one record per USDOT number.
You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.
Once built, one call from your code
Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get registration and authority status” would look like.
curl https://api.fous.com/v1/runs \
-H "Authorization: Bearer $FOUS_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"method": "motus.dot.gov/get_registration_status",
"input": {
"usdot_number": "4012345"
}
}'
{
"status": "completed",
"data": {
"usdot_number": "4012345",
"suffix": null,
"legal_name": "Northwind Freight LLC",
"registrations": [
{
"type": "USDOT registration",
"status": "Active"
},
{
"type": "Operating authority, motor carrier of property",
"status": "Active"
},
{
"type": "Operating authority, broker of property",
"status": "Pending"
}
]
}
}
An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.
Motus’s own options
FMCSA's notice announcing Motus describes no API for it. Registration changes are made in Motus by signed-in users, fees are recorded through Pay.gov, and the paper forms are still accepted for now, with at least eight business days for review. Anyone can look up a company in Search for Companies without signing in.
| Option | What it covers | What it takes |
|---|---|---|
| Search for Companies | Public lookup by exact USDOT number or by the start of a legal or DBA name. | Nothing: no sign-in. |
| Paper forms | OP-1, MCS-150, MCS-150B, BOC-3 and the other listed forms, accepted until a regulatory change. | Supporting documents including a valid government-issued ID. At least eight business days for initial review. |
| FMCSA Portal | Historic records, to view only. Updates can no longer be made there. | Your existing Portal access. |
| Motus by hand | Registrations, operating authority requests, the biennial update, name and address changes, users and notifications. | A Login.gov account, identity verification and a claimed USDOT number. Fees through Pay.gov where they apply. |

Signing in to Motus
Regulated entities and supporting companies sign in to Motus through Login.gov, and FMCSA staff use MyAccess with a PIV card. The first time, you verify your identity with a government-issued ID and a device with a camera. With Fous you sign in once through Motus's own sign-in with your own account: the login is sealed with AES-256, never returned by the API or written to logs, and code and AI agents never see it.
Worth knowing
- Identity verification comes first
- Every user is identity-proofed on first access: you scan a QR code with a phone or tablet, photograph your ID and take a selfie. Have this done before you build anything on the account.
- Claim your USDOT number before reading it
- Existing carriers follow the Link USDOT Number notification to claim their records. A claim is matched against FMCSA's records, so an outdated address or a mismatched legal name blocks it.
- The FMCSA Portal is view-only now
- Business information can only be updated in Motus. The FMCSA Portal still shows historic records, and the URS was switched off on May 14, 2026.
- Suffixes show only inside Motus
- Newly granted USDOT numbers carry a letter suffix for the registration type, and existing companies get theirs later. Suffixes do not appear in FMCSA's formal correspondence.

Frequently asked questions
Not one that FMCSA describes: its notice announcing Motus mentions no API. Registration changes are made in Motus by signed-in users, anyone can look up a company in Search for Companies, and the paper forms are still accepted for now.
No. Business information is updated only in Motus now. The FMCSA Portal still lets you view historic records, and new USDOT number applications go through Motus since the URS was switched off on May 14, 2026.
Use Search for Companies, which needs no sign-in. Search by the exact USDOT number, or by the first letters of the legal or DBA name. The SAFER Company Snapshot can still be used too.
Yes, as a supporting company or service provider. Blanket companies, financial responsibility filers and transportation service providers set up a business profile, manage users and act for the registrants they represent. A method reads only what your own account can.
No. Fous is an independent product. You use it with your own Motus account, and a method reads and does only what that account can.
