Node API - Optimism


API AuthenticationClick to view API Authentication details
API calls require authentication with API key via Authorization request header or URL property. Calls are made to one of the Optimism Node API endpoints found in your app's dashboard.

For example: https://optimism-mainnet-rpc-archive.datahub.figment.io

Here's some boilerplate to get you started. 
fetch("https://optimism-mainnet-rpc-archive.datahub.figment.io", {
    method: 'POST', // can also be 'GET', 'PUT' or any appropriate method
    headers: {
        "Authorization" : "<api_key>",
        "Content-Type": "application/json" // if method is 'POST'
    },
    body: JSON.stringify({
      // JSON Payload
    })
})

  • blockHash: DATA, 32 Bytes - hash of the block where this transaction was in.
  • blockNumber: QUANTITY - block number where this transaction was in.
  • from: DATA, 20 Bytes - address of the sender.
  • to: DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction.
  • cumulativeGasUsed : QUANTITY - The total amount of gas used when this transaction was executed in the block.
  • gasUsed : QUANTITY - The amount of gas used by this specific transaction alone.
  • contractAddress : DATA, 20 Bytes - The contract address created, if the transaction was a contract creation, otherwise null.
  • logs: Array - Array of log objects, which this transaction generated.
  • logsBloom: DATA, 256 Bytes - Bloom filter for light clients to quickly retrieve related logs. It also returns either :
  • root : DATA 32 bytes of post-transaction stateroot (pre Byzantium)
  • status: QUANTITY either 1 (success) or 0 (failure)

eth_getBlockRange

Like eth_getBlockByNumber but accepts a range of block numbers instead of just a single block.
