# Coin Data by ID

> Everything CoinGecko holds on one coin: profile, links, categories, contract addresses and full market data.

Everything CoinGecko holds on one coin, selected by `id`: `description`, `links`, `image`, `categories`, `platforms` and `detail_platforms` (contract addresses per chain), `market_cap_rank`, and a `market_data` block carrying `current_price`, `market_cap`, `total_volume`, `fully_diluted_valuation`, `ath` and `atl` with dates and change percentages. The heavy sections are opt-in via `market_data`, `community_data`, `developer_data`, `tickers`, `sparkline` and `localization` — leave them off unless needed, the full payload is large. Use it for a coin profile. For a price table across many coins use [`get_coingecko_coins_markets`](/docs/api-reference/coingecko/get_coingecko-coins-markets); to look the same coin up by contract address use [`get_coingecko_token_data`](/docs/api-reference/coingecko/get_coingecko-coins-id-contract-contract-address).
