What you can build on the Customer Space

  • Get hourly consumption

    Build this

    Reads My Consumption Profile (Portrait de ma consommation) for one account, hour by hour or day by day, in kWh, with the outside temperature for each day.

    Takes
    Account number, start date, end date, hourly or daily
    Returns
    Date, hour, consumption in kWh, outside temperature for the day

  • Get consumption to date and forecast

    Build this

    Reads, in My Consumption Profile, the electricity used so far in the current billing period and the forecast for the whole period.

    Takes
    Account number
    Returns
    Billing period start, consumption to date in kWh, forecast for the period

  • Find the peak call for power

    Build this

    Reads the power curve in the consumption history for a period and finds when the call for power was highest, the moment behind the puissance facturée (billed demand).

    Takes
    Account number, start date, end date
    Returns
    Account number, peak call for power in kW, date and time of the peak

  • Get billing history

    Build this

    Reads the billing history of one account in the Customer Space: each bill with its amount to pay and payment deadline.

    Takes
    Account number, bills since (optional)
    Returns
    Account number, bill date, amount to pay, payment deadline

Automate the Customer Space 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.

  • Yesterday's hourly consumption, every account

    Build this
    Starts
    Every day at 6:00 Eastern time
    Step 1
    For each account number you list, get yesterday's hourly consumption from My Consumption Profile.
    Step 2
    Stop for an account when no hours come back, as happens at the start or end of a billing period.
    Step 3
    Post each account's hours in kWh to your energy management system's webhook.

  • Weekly billing-period forecast for every site

    Build this
    Starts
    Every Monday at 7:00 Eastern time
    Step 1
    For each account number, get the consumption to date and the forecast for the current billing period.
    Step 2
    Keep the accounts whose forecast changed since the last run.
    Step 3
    Email you one table: account, consumption to date, forecast, and the change.

  • New bills handed to accounting

    Build this
    Starts
    Every weekday at 8:00 Eastern time
    Step 1
    For each account number, get the billing history.
    Step 2
    Keep the bills that were not there on the last run.
    Step 3
    Post each new bill's account number, bill date, amount to pay and payment deadline to your accounting webhook.

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 hourly consumption” 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": "hydroquebec.com/get_hourly_consumption",
    "input": {
      "account_number": "299000000000",
      "start_date": "2026-11-10",
      "end_date": "2026-11-10",
      "granularity": "hourly"
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "account_number": "299000000000",
    "unit": "kWh",
    "days": [
      {
        "date": "2026-11-10",
        "outside_temperature_c": 2.5,
        "hours": [
          {
            "hour": "00:00",
            "kwh": 52.4
          }
        ]
      }
    ]
  }
}

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 Customer Space’s own options

Hydro-Québec's customer pages describe the Customer Space and its tools, and no API for reading your account data. My Consumption Profile shows up to two years of consumption and exports it to a spreadsheet. Online Billing emails you when a bill is ready, and a proxy you designate can add your account to their own Customer Space.

Signing in to the Customer Space

The Customer Space signs you in with a password and, since 5 November 2026, a verification code sent by email at every new session. A session lasts about 24 hours. With Fous you sign in once through the Customer Space's own sign-in with your own account: the login is sealed with AES-256, the emailed code is handled, and an expired session is signed back in.

Worth knowing

A code by email at every new session
Since 5 November 2026 the Customer Space asks for a verification code sent by email for each new session, and a session lasts about 24 hours.
Gaps around the billing period's edges
At the start or end of a billing period, consumption is not available in the Customer Space. Users report that it returns two or three days after the period begins.
Two years of consumption
My Consumption Profile shows up to two years of consumption and compares a period with the same period last year. Keep anything older in your own system.
Proxies and account numbers
A proxy you designate adds your account to their own Customer Space and does transactions on your behalf. Your account number starts with 299, has 12 digits and is printed at the top of your bill.

Frequently asked questions

Hydro-Québec's customer pages describe no API for your account data. You read it in the Customer Space, where My Consumption Profile exports consumption to a spreadsheet, and Online Billing emails you when a bill is ready, with the amount to pay.

Up to two years, in My Consumption Profile. It shows consumption by year, month, day or hour, annual consumption in dollars or kWh, and the outside temperature recorded in your region on a given day.

Consumption is not available in the Customer Space at the start or end of a billing period. Users report that it comes back two or three days after the period begins, so a daily workflow should skip accounts that return no hours.

Yes. The power curve in your consumption history shows when the call for power was highest during the period, which explains the cost of the puissance facturée (billed demand).

No. Fous is an independent product. You use it with your own Customer Space account, and a method reads and does only what that account can.
