How to query which tokens are available to be swapped through 0x API

Step-by-step guide for querying which tokens are available to be swapped through 0x API.

0x supports trades for all ERC20 tokens that are aggregated from our aggregated liquidity sources. This also includes Buy / Sell tax tokens. Currently, we support over 9 million tokens in the EVM landscape.

The only exceptions to the entire token list are tokens blocked for legal and/or compliance reasons.
