What is the Yahoo Finance Chart API?

The Yahoo Finance chart endpoint is a free, key-free API returning stock market data — current quotes, historical open/high/low/close prices, volume and metadata — for equities, ETFs, indices, currencies and commodities.

Free stock market data is genuinely scarce; nearly every provider gates it behind registration and tight quotas. This Yahoo endpoint remains publicly accessible and covers global equities, ETFs, indices, forex and crypto.

It is undocumented and unsupported, which is the honest caveat. Yahoo has changed and restricted these endpoints before, and it requires a browser-like User-Agent to respond at all. Treat it as convenient rather than dependable, and do not build anything critical on it without a fallback.

Common errors and how to fix them

401 or 429 without a browser User-Agent

Yahoo rejects default HTTP client user agents.

Fix: Send a browser-like User-Agent header; without it the endpoint refuses to respond.

Parallel arrays are confusing

Timestamps and OHLC values are separate arrays.

Fix: Zip them by index — timestamp[i] corresponds to quote[0].close[i].

Nulls inside the price arrays

Gaps occur on non-trading periods.

Fix: Filter nulls before charting rather than plotting them as zero.

Yahoo Finance Chart API — frequently asked questions

Is the Yahoo Finance API official?

No. These endpoints are undocumented and unsupported. They work today and are widely used, but Yahoo has restricted them before — do not build anything critical on this without a fallback.

Why do my requests get rejected?

Yahoo blocks default HTTP client user agents. Send a browser-like User-Agent header and the endpoint responds normally.

How is the price data structured?

As parallel arrays: `timestamp` alongside separate open, high, low, close and volume arrays. Zip them by index to reconstruct candles.

Can I use this commercially?

Be careful. Yahoo's terms restrict redistribution of market data. For a commercial product, use a licensed market data provider.
