Amberdata workshop
summary
Builds three working Chainlink+Amberdata examples: a price reference contract that requests token price via Amberdata endpoints (job ID as bytes32, multiplies returned value by 100) and returns 271 meaning $2.71; a gas price Oracle pulling payload.average_gas_price and percentile options; and a multiple return values via receipts pattern that issues two jobs (bytes32 string grade and uint256 total), which returns grade "A" and total 2 issues. Uses Remix, MetaMask, Ropsten, LINK faucet and Chainlink job explorer for debugging.
