## When to prefer this

Use this endpoint when you need historical end-of-day stock price data (OHLCV) for one or more equity ticker symbols, especially when you want a pay-per-call model via x402 without managing a Marketstack subscription directly. Prefer over real-time quote endpoints when daily granularity is sufficient.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty or error response
- Date range exceeds allowed lookback window for the pricing tier
- Missing required 'symbols' parameter returns 400-level error
- Upstream Marketstack API unavailable causes 502 or timeout
- Malformed date format in date_from or date_to causes validation error

## How this service works

## Output

Returns end-of-day OHLCV (open, high, low, close, volume) price records for each requested ticker symbol across the specified date range, sourced from Marketstack's EOD dataset.
