Which token pair will be good to test 0x quote api on testnet?

I want to test the 0x quote API on a testnet before deploying to mainnet. But as it seems testnet don’t have any ERC20 token for which sufficient liquidity is available as I have tested with this endpoint:
https://mumbai.api.0x.org/swap/v1/quote?buyToken=0x2e3A2fb8473316A02b8A297B982498E661E1f6f5&sellToken=0xE3981f4840843D67aF50026d34DA0f7e56A02D69&sellAmount=1000000000000000000. Here I am swapping BAL → wETH but it’s giving me error:

  "code": 100,
  "reason": "Validation Failed",
  "validationErrors": [
      "field": "sellAmount",
      "code": 1004,

so for which token pairs should I test the 0x quote API, any suggestions?

Hi @Rishabh

If you have a question about building on 0x, please ask it on StackExchange. This forum is not set up to provide technical help.

  1. visit https://ethereum.stackexchange.com/
  2. register (optional but recommended) and ask your question
  3. be sure to use the ‘0x’ tag so we’re properly notified

Where can I see previous questions asked?
