<Accordion title="How can I find the tokens that 0x supports for trading?">
0x supports all tokens by default except those blocked for compliance reasons.

Note: Balancer V3 pool tokens (BPTs) are not supported by 0x API. Selling a
BPT is effectively redeeming an LP position, which 0x API does not support —
it routes trades between tokens rather than entering or exiting liquidity
pools. To exit a Balancer V3 position, withdraw through Balancer first, then
swap the underlying tokens through 0x.
0x supports all tokens by default except those blocked for compliance
reasons, and a small number of token types that are incompatible with the 0x
settlement contracts:

- **Balancer V3 pool tokens (BPTs)** — Selling a BPT is effectively redeeming
an LP position, which 0x API does not support — it routes trades between
tokens rather than entering or exiting liquidity pools. To exit a Balancer
V3 position, withdraw through Balancer first, then swap the underlying
tokens through 0x.
- **ERC777 tokens** — Tokens implementing the ERC777 standard (including close
variants such as $AMP) are not supported for sale via 0x API. ERC777 transfer
hooks are incompatible with how 0x settles trades. To trade these tokens,
convert them to a standard ERC20 representation where one exists.
