How this service works
Pay-per-call data API for AI agents. No API key, no account, no signup — pay USDC on Base (eip155:8453) per request; free /api/meta lists all 24 endpoints. One call each: web page to LLM-ready text and link previews; China A-share quotes and limit-up pool; Chinese text and pinyin; Base/Ethereum on-chain reads (address, token, ERC-20 balances, tx, blocks, transfer history, gas price in USD); NFT records (collection, owner, and ipfs:// tokenURI resolved through public gateways); full-page screenshots; email verification without sending mail; ENS forward/reverse resolution; smart-contract due diligence (ABI, verified source, proxy); token security facts (owner, renounced ownership, paused, bytecode capability selectors); domain dossier (RDAP, DNS, TLS certificate, HTTP facts, hosting network); a one-call rule-based contract verdict (published-weights exposure score, owner/pause/proxy/capability facts, every reason with evidence); and an ERC-20 allowance risk check that returns the live allowance matrix for one wallet across up to 10 spenders (unlimited flags, contract/EOA status, exact revoke calls) with a single verdict.
Output
Returns a JSON object with: ok flag, block number, chain, contract address, a facts object (owner, paused, symbol, is_erc20, verified, renounced, is_contract, is_proxy_like, signal_counts by severity), an array of scored reasons with codes, detail strings, and weights, a verdict object (band like 'low'/'elevated'/'high', label, numeric score 0-100, headline string), a confidence object (level, missing fields if any), and a disclaimer noting this is rule-based, not an audit.
Example use cases
DeFi token due diligence before swap
“Before I swap into this token, can you check the contract 0xAbc123...def456 on Base — I want to know its exposure score, whether the owner has renounced control, and if it can mint or blacklist wallets?”
NFT project contract risk check
“I'm about to mint from a new project — can you run a verdict on contract 0x1234...abcd on Ethereum and tell me if it's a proxy, whether the source is verified, and what the overall risk band is?”
Automated portfolio token screening
“Screen the token at 0xDeadBeef...1234 on Base for me — I need the rule-based verdict score, any attention-level capability signals like pause or blacklist, and a summary headline so I can decide whether to hold it.”
Technical details
Endpoint
GEThttps://api.zlovev.com/api/chain/verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, single-call risk verdict on a smart contract or ERC-20 token with weighted scoring across multiple risk dimensions — ownership, proxy, pause, bytecode capabilities, and source verification — without having to manually call separate ABI, source, and token-security endpoints and combine results yourself. It is ideal for pre-trade screening, portfolio monitoring, or user-facing risk alerts in DeFi agents. Prefer alternatives if you need a full security audit, raw ABI, or granular on-chain transaction history rather than a synthesized verdict.
Side effects
- Invalid or non-checksummed address returns 400 with validation error
- Address not a contract (EOA wallet) may return is_contract: false with limited facts
- Unsupported chain value returns 400 enum error
- Unverified contract source reduces confidence level to 'partial' with missing fields listed
- Network congestion or RPC failure may cause 503 or timeout
- Same idempotency key with different address/chain combination returns error or ignores key
