ZkSync API issue for blockNumber return

[yaanakbr]

Environment

Testnet

Provide a brief description of the functionality you're trying to implement.

Hey there :) I am using zkSync API to return the latest block, if I use:

https://goerli-api.zksync.io/api/v0.2/blocks?from=latest&limit=1&direction=older

It returns:

{"request":{"network":"goerli","apiVersion":"v02","resource":"/api/v0.2/blocks","args":{"direction":"older","from":"latest","limit":"1"},"timestamp":"2023-07-15T14:23:23.171251873Z"},"status":"success","error":null,"result":{"list":[{"blockNumber":90613,"newStateRoot":"302d877f443608c27be63f9aade9a92c4ab313634c542d2f01b49dc13ce0ad5b","blockSize":26,"commitTxHash":"0xe12648203afcd3a08a88395c351ddfe3c23af82ae7fe001823bba530a6fd463a","verifyTxHash":"0x5bd281ab0c6e24d1f0571211b697181b3a63ccd38168f0db25c2f755a1c7a9ad","committedAt":"2023-07-15T13:56:12.160686Z","finalizedAt":"2023-07-15T13:59:32.164192Z","status":"finalized"}],"pagination":{"from":90613,"limit":1,"direction":"older","count":90613}}}

But if you look on the block explorer, the latest blockNumber is currently:

https://goerli.explorer.zksync.io/block/9699807

How do I input the API to return blockNumber to give me 9699807

Sorry if submitting an issue was wrong by the way. I didn't know if this was expected behavior but seems wrong to me.

Thank you for any help/feedback in advance!

I believe that you're using the older API that's using zkSync Lite instead of zkSync Era. Try the following intead:

curl -X POST -H "Content-Type: application/json" \
--data '{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": [  ]}' \
"https://testnet.era.zksync.dev"

That should return:
{"jsonrpc":"2.0","result":"0x9653e4","id":1}

And 0x9653e4 is hex for 9851876

Hey @MexicanAce thank you for this! Is there any documents that can support this? I was looking at the V2 version so I thought it was the newest.

Also @MexicanAce just to confirm I can do this via HTTP API and not only RPC, correct? I specifically need the HTTP API call.

Unsure exactly what you mean, but this HTTPS POST request is all that exists right now
