public_key can be obtained using v2/tonconnect/stateinit

const { data } = await axios(
    `https://${
      body.network === '-3' ? 'testnet.' : ''
    }tonapi.io/v2/tonconnect/stateinit`,
    {
      method: 'POST',
      data: {
        state_init: body.proof.state_init,
      },
    }
  )

@peng-xiao-shuai thanks, that works!

Is there any other methods to get public key instead of tonapi.io? It is proprietary project and they can shutdown v2 api in few years how did they did it with v1

• Get the wallet pubkey via the contract wallet's get method. (https://tonapi.io/api-v2#operations-Connect-getTonConnectPayload) /v2/tonconnect/stateinit

• If the contract is inactive, this method will not work; you'll need to parse the walletStateInit provided by the frontend.
