Overview

Times Adder is a lightweight utility API that accepts an array of time values and returns their total sum. It is perfect for projects that need to calculate total durations, such as video playlists, workout timers, or task schedulers. No authentication is required, so you can integrate it immediately with a simple POST request.

💡

Beginner Tip

Send a POST request with a JSON body containing an array of time strings in HH:MM:SS format, and the API returns their combined total. Make sure to set the Content-Type header to application/json so the server correctly parses your request body.

Common Errors & Troubleshooting

400 Bad Request — invalid format Time strings are not in the expected HH:MM:SS format.
✓ Always use the full three-part format including hours: "00:05:30" for five minutes and thirty seconds, not just "5:30".
Missing Content-Type header causes empty body Without the Content-Type: application/json header, the server may not parse the JSON body.
✓ Always include -H "Content-Type: application/json" in your curl command or set the equivalent header in your HTTP client.
Incorrect result for times over 24 hours Some implementations roll over at 24 hours so verify expected behavior.
✓ Test with a sum exceeding 24 hours to confirm the API returns values like "25:00:00" rather than resetting to "01:00:00".
