# Cryptocurrency Data Streams

> For the complete documentation index, see [llms.txt](/llms.txt).

Some crypto streams below are sourced from a single exchange's order book rather than a liquidity-weighted composite. See [Crypto Top-of-Book Streams](/data-streams/concepts/crypto-top-of-book-and-mark-price) for details on this stream type, its data sources, and schema.

Live values such as feed contract addresses are not inlined here. Wait for the official API to obtain current data.
