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 past bills and payments” 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": "eversource.com/get_past_bills_and_payments",
    "input": {
      "service_account": "51234567890",
      "months_back": 2
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "service_account": "51234567890",
    "nickname": "Acme warehouse, Route 9",
    "balance": 1842.17,
    "bills": [
      {
        "bill_date": "2026-11-03",
        "amount": 1842.17,
        "due_date": "2026-11-28"
      }
    ],
    "payments": [
      {
        "payment_date": "2026-10-24",
        "payment_amount": 2105.4
      }
    ],
    "currency": "USD"
  }
}

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.

Eversource’s own options

Eversource does not publish an API for its online account. Smart meter customers can share their electricity usage with approved service providers through Share Data with Providers, and paperless billing can email each bill as a PDF. Bills, payments and usage for each service account are otherwise read in the online account by hand.

OptionWhat it coversWhat it takes
Share Data with ProvidersElectricity usage history, shared automatically with service providers you approve, such as a solar provider.A smart meter and an online account. You choose the providers and can remove their access.
Paperless billing with PDFAn email when each bill is ready, with the bill attached as a PDF if you ask for it in your alert settings.Paperless billing turned on. It starts with your next billing cycle.
The online account by handYour Account, Past Bills and Payments for 36 months, Energy Usage Details and Account Settings, one service account at a time.An online account with each service account added to it.

Signing in to Eversource

Residential and business customers sign in on one page with an email or username and a password. One online account can hold several gas and electric service accounts. With Fous you sign in once through Eversource's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Each service account must be added first
Gas and electric services at several locations may not all appear in the online account. Adding one takes its 11-digit service account number, the last four digits of the ID used to start service and a ZIP code.
36 months of bills
Past Bills and Payments goes back 36 months. An archive older than that has to be built up from regular reads.
Daily figures need a smart meter
Usage over the course of a day, Bill Forecast and Share Data with Providers are for smart meter customers. Eversource says some tools need days or months of data before they are complete.
A pending auto payment cannot be edited
Auto pay draws from a bank account, not a credit card, a number of days before the due date that you pick. To change a pending payment, you cancel it and make a one-time payment.
