# Coin Historical Chart

**API:** Data API

**Endpoint:** `GET /v1/beta/coingecko/coins/{id}/market_chart`

**Tags:** CoinGecko

Historical series for one coin over a trailing window set by `days`, returned as three parallel arrays: `prices`, `market_caps` and `total_volumes`. Each entry is a two-element pair of timestamp and value, and the timestamp is in milliseconds. Granularity follows `days` automatically, or force it with `interval` (`daily` or `hourly`). Use it to chart a trend ending now. For an explicit start and end use `get_coingecko_coins_id_market_chart_range`; for candlesticks use `get_coingecko_coins_id_ohlc`; for one specific past day use `get_coingecko_coins_id_history`.
