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.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

JSON Response · Illustrative 
{
  "status": "success",
  "data": {
    "result": "Data from Times Adder",
    "description": "With this API you can add each of the times introduced in the array sended",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Field Reference

result The total summed time in HH:MM:SS format.
times Echo of the original time strings that were sent in the request.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request 
const url = "https://api-times-adder.vercel.app/add";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

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".

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
