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 TRS cases that need attention” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "arbfile.org/get_trs_cases",
    "input": {
      "case_status": "Needs Attention"
    }
  }'

{
  "status": "completed",
  "data": {
    "case_status": "Needs Attention",
    "features": [
      {
        "case_id": "2600418B7-C1",
        "loss_state": "Florida",
        "loss_date": "2026-08-14",
        "insurance_company": "Acme Mutual Insurance",
        "insured_name": "Acme Logistics LLC",
        "coverage": "Collision",
        "representative": "Northwind Claims Unit",
        "due_date": "2026-11-19",
        "status": "In Hearing"
      }
    ],
    "count": 1
  }
}

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.

Arbfile’s own options

AF says that by separate agreement it may let members or their third-party administrators interface directly with its services through an API. AF Client, software your IT team deploys, prints documents straight to an E-Subro Hub claim. Otherwise you work in TRS and E-Subro Hub on the website, where TRS Reports and an Excel Export give you files.

Signing in to Arbfile

You select Login to MyArbfile and enter your username and password on the Sign In page, with three attempts allowed. AF emails you when your account signs in from a new device or browser. With Fous you sign in once through that same page with your own user ID: the login is sealed with AES-256, never shown to code or AI agents, and an expired session is signed back in.

Worth knowing

Closed cases leave the TRS Worklist

Closed cases drop off the Worklist after 70 days with no activity. Read decisions while they are there, or use the Features Published Detail report.

My Worklist is not every demand

A demand appears on E-Subro Hub My Worklist only when it has an action flag, a message or a task, and is owned by you or your business unit. Rows are sorted by Date Issued, oldest first.

Every piece of evidence needs a type

E-Subro Hub asks for at least one evidence type on every uploaded file before you save, so a method that adds evidence takes the type. A lock icon makes each document private or public.

One user ID per person

AF asks that every individual has their own user ID and prohibits shared logins. Your company's security administrator creates accounts, and TRS Reports need report privileges.
