Output
Returns a structured token report for the specified contract address on the given EVM chain. In 'voll' (full) mode this includes upgrade/proxy history gathered via log scan; in 'schnell' (fast) mode it skips the log scan. The report contains on-chain token metadata, contract details, and where applicable a history of contract upgrades.
Example use cases
DeFi due diligence on new token
“Before I invest, can you pull a full on-chain report for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum? I want to see everything including any upgrade history.”
Quick token check before listing
“I need a fast token report — no upgrade history needed — for contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon. Just give me the quick scan.”
Audit proxy upgrades on Arbitrum token
“Can you check whether the token at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum has ever been upgraded? Run the full depth scan so I get the complete upgrade history.”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/token/reportWhen to prefer
Use this endpoint when you need structured on-chain analysis of an ERC-20 token contract on a major EVM chain, especially when upgrade/proxy history is relevant for due diligence. Prefer the 'schnell' depth for fast lookups where upgrade history is not needed. Choose this over generic block explorers when you need a machine-readable, structured report rather than a human-readable UI.
Side effects
- Invalid token address format (must match ^0x[0-9a-fA-F]{40}$) returns a validation error
- Unsupported chain name returns an enum validation error
- Contract address does not exist on the specified chain returns empty or error response
- Payment failure via x402 protocol prevents access to the endpoint
- Log scan timeout or RPC failure may cause 'voll' mode to partially fail or fall back
