Discontinued

This API no longer responds. Our last check on 2026-04-05 found no working endpoint — the service appears to have shut down or moved. The documentation, code samples and score below are kept for reference only; do not build against this API. See working Finance APIs →

Overview

IEX Cloud provides programmatic access to realtime & historical stock and market data via REST API.

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.

stock price and symbol
open/close/high/low values
trading volume
market cap
historical price data

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 IEX Cloud",
    "description": "Realtime & Historical Stock and Market Data",
    "timestamp": "2025-01-15T10:00:00Z"
  }
}

Implementation Example

Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.

Request
const url = "https://iexcloud.io/docs/api/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

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.
