I'm finding Reference document for 0x v3. However i can find only for 0x v4 in here(https://protocol.0x.org/en/latest/) where can i find the document for v3?
Original question answered by Nikita on Discord, posting resources here in case someone else needs it in the future
Most of the docs have been updated to v4 but here is a link to the v3 specs in github https://github.com/0xProject/0x-protocol-specification/blob/master/v3/v3-specification.md
There is also some reference to v3 in the swap sdk https://docs.swapsdk.xyz/readme-1
