Simple Price

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; if you hold a contract address rather than an id use get_coingecko_simple_token_price_id.
