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 “Download interval usage data” would look like.

Example request
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "firstenergycorp.com/download_interval_usage",
    "input": {
      "account_number": "110000000001",
      "from": "2026-11-09",
      "to": "2026-11-09"
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "account": "Acme Distribution, 400 Industrial Pkwy",
    "account_number": "110000000001",
    "intervals": [
      {
        "start": "2026-11-09T00:00:00-05:00",
        "end": "2026-11-09T00:15:00-05:00",
        "kwh": 41.6,
        "kw": 166.4,
        "kva": 178.9,
        "kvar": 65.7,
        "power_factor": 0.93
      }
    ],
    "count": 96
  }
}

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.

FirstEnergy’s own options

FirstEnergy's customer help pages offer no API. In the online account, Analyze Usage has a Green Button Download of interval data as CSV or XML, and Billing and Payment History is on screen. Third parties such as curtailment service providers, holding each customer's Letter of Authorization, can get up to 24 months of hourly data in Excel through a web portal or by EDI.

Signing in to FirstEnergy

FirstEnergy asks for a username and password. Multi-factor authentication is optional: a one-time code by text message, a phone call, or an authentication app. With Fous you sign in once through FirstEnergy's own sign-in with your own account, and the login is sealed with AES-256. An account that signs in with a password alone is signed back in when its session expires.

Worth knowing

One account at a time
Billing and Payment History and Analyze Usage show the account chosen in the Account Selector at the top of each page. So each method you build takes an account number, and a workflow loops over your accounts.
Interval data arrives as a file
Green Button Download gathers the data after you press Download and saves a CSV named after the account with a date and time stamp. kWh, kVA, kVAr, kW and power factor appear when the Usage Trends view is set to Power.
Service requests take two business days
FirstEnergy may need at least two business days to process a start, stop or move request and confirms by email. Requests can be made up to 90 days ahead and not for weekends or holidays.
Third-party access needs a letter per customer
A third party must keep a Letter of Authorization from each customer on file, and FirstEnergy may ask for proof at any time. Data not available through the portal or EDI is billed at $53 an hour.
