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 a filed quarter's wage detail” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "thesource.jfs.ohio.gov/get_filed_wage_detail",
    "input": {
      "employer_id": "0000000",
      "quarter": "2026-Q3"
    }
  }'

{
  "status": "completed",
  "data": {
    "employer": "Acme Fabrication LLC",
    "employer_id": "0000000",
    "quarter": "2026-Q3",
    "employees": [
      {
        "name": "Employee One",
        "ssn": "XXX-XX-1234",
        "gross_wages": 14820,
        "weeks": 13
      }
    ],
    "employee_count": 1,
    "total_gross_wages": 24195.5
  }
}

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.

The SOURCE’s own options

ODJFS describes no API for The SOURCE. Ohio employers and their agents must file quarterly wage reports electronically: typed into The SOURCE online, uploaded there as a file built to the JFS 20233 specifications, or filed through the Ohio Business Gateway. ODJFS recommends online entry for employers with fewer than 250 employees.

Signing in to The SOURCE

The SOURCE signs employers and agents in with a username and password. You set them up once under Authenticate My Account with your Employer ID, FEIN and either the most recently filed quarter's gross wages or your last payment, then choose security questions. With Fous you sign in through The SOURCE's own sign-in with your own account, and the login is sealed with AES-256: code and AI agents never see it.

Worth knowing

A report is due even with no wages

Every quarter needs a report, even when you had no employees and paid no wages. It is due by the last day of the first month after the quarter, or the next business day when that falls on a weekend or holiday.

A missing report brings a notice and penalties

An unfiled quarter brings a Notice of Failure to File (JFS-20158), and penalties and interest are assessed once the report is processed. You can apply for a waiver of those assessments.

Agents need each employer's authorization

An agent sets up access with its Agent ID plus the Employer ID, FEIN and most recently filed quarter's gross wages or last payment of a client that authorized it in writing. Employers can also add an agent from their own portal.

Corrections are made one quarter at a time

Wage corrections can be entered in The SOURCE or uploaded in a JFS 20233 file. On paper, each quarter needs its own JFS-20129, with the original and corrected data and a reason code, and no negative figures.
