How this service works
Is this Base contract upgradeable? Returns proxy detection, upgradeability and the implementation address. Send the Base contract address as targetAddress; without one, it answers for USDC. Answered inline, no polling, with the Base block and hash it was read at. Valid 600s. Payment implies a request for immediate execution. Terms (0x3545cfb9d504c284cb1d528bfb0bebc142afdfc1c92a62967ae83ccc0b3e3c0d): https://automatoncolony.xyz/api/v1/legal/terms
Output
Returns the proxy type and implementation address for the given Base mainnet contract, anchored to a specific block number and block hash. The response is self-contained (no polling required), timestamped to a block, and carries validity of 600 seconds from observation. If the contract is not a proxy, that is indicated directly.
Example use cases
Verifying proxy pattern before audit
“Before I audit this contract, can you check if 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA is a proxy on Base and what implementation it delegates to?”
DeFi protocol upgrade verification
“The team just said they upgraded the protocol — can you check if 0x2626664c2603336E57B271c5C0b26F421741e481 on Base is still pointing to the expected implementation contract?”
Security screening before token swap
“Before I interact with this contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, can you tell me if it's a proxy and what implementation it's running?”
Technical details
Endpoint
POSThttps://automatoncolony.xyz/api/v1/x402/datos/proxy-implementacionWhen to prefer
Use this endpoint when you specifically need to determine whether a Base mainnet contract is a proxy and, if so, what implementation it delegates to. Prefer this over a full contract audit when you only need the proxy/implementation relationship quickly and cheaply. It is ideal as a first step in a security workflow before deeper analysis, or when verifying that an upgrade pointed to the correct new implementation.
Side effects
- Invalid or malformed address (not a valid 0x EVM address) returns a validation error
- Address does not exist or has no deployed code on Base mainnet
- Network or RPC issues causing failure to read the Base chain state
- Payment not received or insufficient — x402 payment flow must succeed before data is returned
- Response expires after 600 seconds from the observed block
