How this service works
Thirty x402 v2 pay-per-call APIs by 100BTC. Listing data is generated from each live HTTP 402 challenge and runtime Bazaar schema.
Output
Returns a JSON object containing the contract address, a risk level classification (e.g. LOW, MEDIUM, HIGH), a plain-English explanation of the findings, and the bytecode size in bytes. Useful for quick pre-interaction security screening of deployed EVM contracts.
Example use cases
DeFi token contract safety check
“Before I ape into this token, can you analyze the contract at 0xdAC17F958D2ee523a2206206994597C13D831ec7 and tell me if there are any sketchy backdoors or rug-pull mechanics in the bytecode?”
NFT contract risk review
“I'm about to mint from this NFT project — can you decompile the contract 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D and give me a risk level so I know if it's safe?”
DeFi protocol audit pre-check
“Our team is considering integrating with a lending protocol at 0xAave... — decompile the contract and flag any suspicious opcodes or backdoor patterns before we proceed.”
Technical details
Endpoint
POSThttps://vps-fc89c157-1.taila28d02.ts.net:10000/api/decompile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, automated risk classification of an EVM smart contract before interacting with it, integrating it into a product, or presenting it to users. It is particularly useful for DeFi agents, wallet UIs, and trading bots that need on-the-fly security signals without running a full manual audit. Prefer this over general-purpose blockchain explorers when you need a structured risk verdict and natural language explanation rather than raw bytecode or ABI data.
Side effects
- Invalid or non-existent contract address returns an error
- Contract with no deployed bytecode (EOA address) may return empty or error response
- Network timeouts fetching bytecode from chain
- Unrecognized opcode patterns may result in incomplete decompilation
- Payment failure via x402 protocol results in HTTP 402 with no analysis
