Example prompt: Can you pull up the price history for the Sony WH-1000XM5 headphones and tell me if now is a good time to buy or if the price is likely to drop — I want to know the historical low and the recent trend.

## When to prefer this

Use this endpoint when you need to evaluate whether a current price is a good deal relative to historical pricing. Prefer this over a live price comparison endpoint when the user is asking about price trends, historical lows, or buy-now-or-wait decisions rather than just finding the cheapest current price.

- Insufficient historical data for a meaningful trend — returns partial data

## Output

Returns a time-series of historical prices for the requested product, the all-time or recent historical low price, and a trend signal (rising/falling/stable) that informs a buy-now-or-wait recommendation.
