How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns the proxy kind (e.g. transparent, UUPS, beacon, EIP-1167 minimal proxy, or none), the implementation contract address, the admin address (if applicable), and the beacon address (if applicable) for the given contract on Ethereum or Base.
Example use cases
Audit upgradeable contract before integration
“I'm about to integrate with the contract at 0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f on Ethereum — can you check what kind of proxy it is and tell me the implementation address and admin?”
Verify contract upgrade on Base
“We just deployed an upgrade on Base — can you confirm that 0x4200000000000000000000000000000000000010 is still pointing to the right implementation contract and who the admin is?”
Security review of unknown proxy
“Someone sent me this contract address on Ethereum: 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D — can you tell me if it's a proxy, what kind, and what the actual implementation behind it is?”
Technical details
Endpoint
POSThttps://tanod.dev/v1/chain/proxy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine the proxy architecture of a specific smart contract on Ethereum or Base — especially before integrating with or auditing an upgradeable contract. Prefer this over manual ABI inspection or block explorers when you need machine-readable proxy metadata in an automated agent workflow.
Side effects
- Invalid or malformed contract address returns a validation error
- Contract address does not exist on the specified chain returns empty or null proxy fields
- Network unavailable or node timeout may return a service error
- Non-proxy contract returns proxy kind as null or 'none' with no implementation/admin
- Unsupported chain value returns schema validation error
