# Simple Price

> The cheapest price lookup — current price for known coin ids, with optional market cap, volume and 24h change.

The cheapest price lookup: pass comma-separated CoinGecko `ids` and `vs_currencies`, get back a map keyed by coin id. Field names are built from the quote currency — with `vs_currencies` set to usd you get `usd`, plus `usd_market_cap`, `usd_24h_vol`, `usd_24h_change` and `last_updated_at` when the matching `include_market_cap`, `include_24hr_vol`, `include_24hr_change` and `include_last_updated_at` flags are set. Use it whenever the ids are already known and only current numbers are needed. For rank, supply or all-time-high data use [`get_coingecko_coins_markets`](/docs/api-reference/coingecko/get_coingecko-coins-markets); if you hold a contract address rather than an id use [`get_coingecko_simple_token_price_id`](/docs/api-reference/coingecko/get_coingecko-simple-token-price-id).
