Chainlink Node Operator creds

Hosted on : http://34.125.213.96/

Request compute steps (Quickstart)

https://goerli.etherscan.io/address/0xfF9aa21FC6aA2fEae61cC776f3F2B23f0Ad5dE4e

1. Deploy the computeCaller.sol and RequestOutputLog.sol and fill them with Goerli LINK tokens 5-10.

2. Look for callAPI function and enter the following creds and URL for compute.

oracle_address: 0x33238F4C8C5C71E1A7a2802e290079665f532FbA

jobID compute call: aa491301949d4a4e93d460bdf12c372f

AI model example fileURL: https://raw.githubusercontent.com/madhukar123456/kaggle-kernel/main/python-code/mistraltest.ipynb

3. Status call callStatus

oracle_address: 0x33238F4C8C5C71E1A7a2802e290079665f532FbA

status call jobID: 6c071cdf64374795a5ea4e238505da46

computeID: from 2.

4. Log call callLog

oracle_address: 0x33238F4C8C5C71E1A7a2802e290079665f532FbA

log call jobID: e74117d2ec984537a3a3db4dba6acf86
