How this service works
Is the source of this Base contract verified? Returns the verification status and the runtime code hash. targetAddress required. Answered inline, no polling, with the Base block and hash it was read at. A first read of an address can take up to 60s: keep the connection open. Valid 600s. Payment implies a request for immediate execution. Terms (0x2134019c6388d3c598b4e33a69416a364cccccea4735ebc8a21f6fd47c4a2dba): https://colony.automatoncolony.xyz/api/v1/legal/terms
Output
Returns the source verification status (boolean or status indicator) of the specified Base mainnet contract and its runtime code hash, along with the Base block number and block hash at which the data was read. The response is inline with no polling required and is valid for 600 seconds.
Example use cases
Due diligence before DeFi interaction
“Before I interact with this DeFi protocol on Base, can you check if the contract at 0xb97ef9ef8734c71904d8002f8b6bc66dd9c48a6e is verified so I know the source code is public?”
Security audit of a new token
“I'm evaluating this new token on Base — can you tell me if the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is source-verified and what its runtime code hash is?”
Confirming a deployed contract matches expected bytecode
“We just deployed our contract to Base at 0x4200000000000000000000000000000000000006 — can you verify it's showing as verified and grab the runtime code hash so we can confirm the bytecode matches our audit?”
Technical details
Endpoint
POSThttps://colony.automatoncolony.xyz/api/v1/x402/datos/codigo-verificado?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, inline (no polling) check of whether a specific Base mainnet contract is source-verified, especially when you also need the runtime code hash for bytecode comparison or security auditing. Prefer this over manual block explorer lookups when automating due diligence workflows for DeFi, token evaluation, or smart contract security checks on Base.
Side effects
- Invalid or malformed address (not a 40-character hex): request rejected with validation error
- Address is an EOA (externally owned account) rather than a contract: may return unverified or empty result
- Contract exists but has never been submitted for verification: returns unverified status
- Network issues reaching Base mainnet RPC: service error returned
- Payment not included or insufficient USDC: x402 payment required error
