Quick start with the live website

Start with a browser calculation, then reuse it in a script. Public calculation endpoints do not require an API key during the beta.

1. Choose a calculation

Browse the calculator library or open water pipe pressure loss. Read the input units and model assumptions before calculating. Changing an input clears the previous result so it cannot be confused with the new case.

2. Make your first API request

This shell example calculates current and dissipated power for an ideal 12 V DC source across 6 Ω:

curl 'https://www.engivault.com/api/electrical/dc-resistor' \
  -H 'Content-Type: application/json' \
  --data '{"voltage":12,"resistance":6}'
{
  "success": true,
  "data": {
    "current": 2,
    "power": 24
  }
}

Current is in amperes and power is in watts. The model does not select a resistor rating or account for changing resistance with temperature.

3. Use a worked script

The JavaScript and Python examples compare a water-pipe calculation at two temperatures, handle errors and print results with units. The live API reference documents every available calculation endpoint.

4. Keep your results

After calculating in the browser, use PDF, Excel or JSON export. Calculation history is stored in that browser. The website’s project workspace uses a signed-in account and separate project storage.

A spreadsheet export contains calculation results. It does not install custom Excel functions or a live spreadsheet add-in.

For account access, see accounts and API access. The separately supplied server and integration source are not prerequisites for using this live website.
