Get Contracts Creations

Overview

The Get Contracts Creations endpoint obtains data on smart contracts' creations. At least one of the following parameters must be specified: contract, origin, or caller. The range should be defined by either block_number, timestamp, or block_hash.

Use Cases

Several possible combinations of parameters should be considered, where origin refers to the address of an EOA wallet, contract is the address of a smart contract being created, caller represents the address of a smart contract that triggers the creation of another smart contract. To retrieve specific details about contracts' creations, follow the guidelines below.

1. For getting data on a contract's creation, specify contract.
2. For all contracts' creations initiated by an EOA wallet, specify origin.
3. For all contracts' creations triggered by another smart contract, specify caller.
4. For all contracts' creations triggered by another smart contract but initiated by an EOA wallet, specify both origin and caller.

Querying via Postman

If you prefer querying via Postman, the description of PARSIQ Endpoints for Get Contracts Creations (opens in a new tab) might come in handy. There you will find examples and responses for good and bad requests as well as parameter definitions and their example values.

Usage

import * as Parsiq from '@parsiq/parsiq.js';
 
const client = Parsiq.createClient(process.env.API_KEY, Parsiq.ChainId.ETH_MAINNET);
 
const creations = client.contracts.creations.getByBlockRange(
    1, 'latest',
    {
      contract: ['0xfc934b64a945b0c99e09b9c137dabe271a5a1a06'],
      origin: '0xcc2c2cd417a9c39cf0e48622988dbec0b1b37064',

    },
    {
      limit: 1
    }
);
 
for await (const creation of creations) {
    console.log(creation);
}
