Stock historical bars

Historical OHLCV bars for a symbol. Configurable interval (1m, 5m, 15m, 30m, 60m, 1d, 1wk, 1mo, 3mo) and range (1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max). Intraday intervals are limited by Yahoo to ~60 days of data. Returns a flat array of bars (time, open, high, low, close, volume) ready for charting or backtests.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

This tool is one step in 5 curated multi-tool workflows - agents can fetch the whole sequence as an MCP prompt or call https://agent402.tools/api/skill-packs/{slug}/prompt.

• Options analytics - Price a European option on a live stock: pull the current quote, estimate volatility from recent history, run Black-Scholes for fair value + the full greeks, and check the news for catalysts.
• Financial research - Pull SEC filings, real-time quotes, historical prices, and macro context for a single ticker in one pass.
• Trend analysis - Take any numeric time series - a stock's daily close, a FRED macro indicator, a treasury yield history - and run it through the full quantitative workup: descriptives, moving averages, trend line, outliers, optional correlation against a benchmark, and a deterministic forecast forward with a 95% prediction interval. Everything an analyst writes a notebook for, in one chain of cheap calls.
• Forecasting bake-off - Don't guess which forecasting method to trust. Backtest all four (naive/drift, SES, Holt, Holt-Winters) on a real series, rank by out-of-sample RMSE, then forecast forward with the winner and its 95% prediction interval. Method selection without the hand-waving.
• Cross-asset price monitor - Side-by-side snapshot of a stock and a crypto asset: live quotes, 1-year history, and a date-stamped comparison.
