Fetching Index Price Time-Series Data
To fetch the Dow Jones U.S. Transportation Services Index price time-series data, you will need to utilize the Time-Series Endpoint of the Indices-API. This endpoint allows you to specify a date range and retrieve daily rates for the index.
Making API Calls
To make a successful API call, you will need your unique API key, which is passed into the API base URL's access_key parameter. Here’s how you can structure your API request:
GET https://api.indices-api.com/v1/time-series?access_key=YOUR_API_KEY&symbol=DOW&start_date=YYYY-MM-DD&end_date=YYYY-MM-DD
Replace YOUR_API_KEY with your actual API key, and specify the desired start and end dates for your query. The symbol for the Dow Jones U.S. Transportation Services Index can be found in the Indices-API Supported Symbols list.
Understanding API Responses
The response from the Time-Series Endpoint will provide you with a JSON object containing the requested data. Here’s an example of what the response might look like:
{
"success": true,
"timeseries": true,
"start_date": "2026-03-10",
"end_date": "2026-03-17",
"base": "USD",
"rates": {
"2026-03-10": {
"DOW": 0.00028
},
"2026-03-11": {
"DOW": 0.00029
},
"2026-03-12": {
"DOW": 0.00030
},
"2026-03-13": {
"DOW": 0.00031
