GET > Uint256 Example Job Spec
This is an example v2 (TOML) job spec for calling any public API, retrieving a number , removing its decimals then returning uint256 in one Chainlink API Call. Note that the job calls the fulfillOracleRequest2
function. If you are a node operator, use an Operator contract with this job.
To test it from a smart contract, see this Example.
