Synthora EIP-1967/UUPS/Transparent Proxy Detector
x402
Synthora EIP-1967/UUPS/Transparent Proxy Detector is a paid API for AI agents from rpc-proxy.hergertsynthora.com, paid per call via x402, $0.1/call, status down (last checked 2026-09-15).
Detects the proxy pattern (EIP-1967, UUPS, or Transparent) of a smart contract address on a given chain and resolves its current implementation address.

How this service works
Detect proxy pattern (EIP-1967 / UUPS / Transparent) and resolve the implementation address. Deterministic, Ed25519-signed.
Output
Returns the detected proxy pattern (EIP-1967, UUPS, or Transparent), the resolved implementation contract address, and an Ed25519-signed response confirming the result. If the contract is not a proxy, the response indicates no proxy pattern was found. No charge is applied on upstream failure.
Example use cases
Example prompt
“Can you detect the proxy pattern and resolve the implementation address for the contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet?”
Technical details
Endpoint
POSThttps://rpc-proxy.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need to programmatically determine whether a smart contract is a proxy, which proxy standard it implements (EIP-1967, UUPS, or Transparent), and what implementation contract it currently points to — especially useful for auditing upgradeable contracts, tracking contract upgrades, or building tooling that interacts with proxy-based protocols. Prefer this over manual slot inspection or generic RPC calls when you need a signed, deterministic result.
Side effects
- Invalid or non-existent contract address returns an error or no-proxy result
- Unsupported chain identifier causes a lookup failure
- Contract is not a proxy — pattern detection returns null or no-match
- Upstream RPC node failure results in no charge and an error response
- Malformed address format triggers a validation error
