How this service works

Stock split history for a US stock — execution dates and split ratios with price-adjustment factors.

Output

A list of stock split events for the requested ticker, each containing the execution date, the split ratio (e.g. 4:1), and the corresponding price-adjustment factor used to normalize historical prices.

Example use cases

Example prompt

“Can you pull up the full stock split history for NVIDIA (NVDA), including all the execution dates and split ratios, so I can adjust historical price data correctly?”

Endpoint

When to prefer

Use this endpoint when you need historical corporate-action split data for a US equity — especially when adjusting raw historical price series for split events, backtesting strategies, or calculating split-adjusted returns. Prefer this over general market data endpoints when split ratios and exact execution dates are the primary need.

Side effects

Invalid or unrecognized ticker symbol returns an error or empty result
Ticker is valid but has no recorded splits — returns empty list
limit parameter out of allowed range (max 5000) may return an error or be clamped
Non-US tickers may not be supported and return no data or an error
Service unavailable returns a non-200 HTTP response with error message
