# TokenVerdict Quick — ERC-20 Token Safety Checker > TokenVerdict Quick — ERC-20 Token Safety Checker is a paid API for AI agents from api.youraitools.co, paid per call via x402, $0.015/call, status unknown (last checked 2026-10-23). Runs a rapid on-chain safety audit on a Base ERC-20 token contract and returns a scored verdict (SAFE/UNSAFE) with holder analysis, liquidity, ownership, and sellability checks. ## Facts - Endpoint: GET https://api.youraitools.co/tokenverdict/v1/quick?utm_source=zero.xyz - Price: $0.015/call - Payment: x402 - Status: unknown - Last checked: 2026-10-23 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/tokenverdict-quick-erc-20-token-safety-checker-9f2bfed5 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_bmWffdYSAym7trSpNujBX Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability tokenverdict-quick-erc-20-token-safety-checker-9f2bfed5 ``` Example prompt: Can you check if the Base token at contract address 0x532f27101965dd16442E59d40670FaF5eBB142E4 is safe — I want to know the safety score, whether ownership is renounced, and if I can actually sell it after buying? ## When to prefer this Use this endpoint when you need a fast, scored, machine-readable safety verdict on a specific Base ERC-20 token before trading, listing, or integrating it. It is ideal for pre-trade screening in DeFi bots, due-diligence pipelines, or airdrop evaluation. Prefer this over generic block explorer lookups when you need a single composite score, holder concentration analysis, and a simulated sell test in one call. ## Known failure modes - Invalid or non-existent contract address returns an error or empty result - Token not deployed on Base (chain 8453) — wrong chain addresses will fail or return incorrect data - Unverified contracts may have incomplete 'powers' data since ABI is unavailable - Very new tokens with no DEX pool may lack liquidity and sellability simulation data - Payment failure (non-payment of $0.015 USDC via x402) results in 402 response ## How this service works Token safety report API for Base (honeypot, tax and liquidity check). Full Base ERC-20 token safety report: honeypot / sell simulation with buy, sell and transfer tax and round-trip loss (Uniswap v2/v3/v4, Aerodrome, Pancake), owner powers with function names, proxy and upgrade admin, owner status, liquidity per pool and LP burn, holder concentration, verification, age, data sources and limits, plus SAFE / CAUTION / DANGER and a 0-100 score. ## Output Returns a JSON object with: a numeric safety score (0-100), a verdict string (SAFE/UNSAFE/etc.), confidence level (high/medium/low), token name and symbol, per-check breakdown including contract age, owner address and renouncement status, proxy/upgradeability info, dangerous powers (mint, pause, blacklist, fees), holder count and top-10 concentration, liquidity pool details and USD value, and a simulated buy/sell result with tax percentages. Also includes a list of human-readable reason codes with severity labels (good/info/warning/danger). ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "token" ], "properties": { "token": { "type": "string", "description": "Base (chain 8453) ERC-20 contract address, e.g. 0x532f27101965dd16442E59d40670FaF5eBB142E4" } }, "description": "Search intents: token security report, honeypot test, buy sell tax check, liquidity lock check, base token audit, erc20 owner powers" } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "properties": { "key": { "type": "string" }, "name": { "type": "string" }, "tier": { "type": "string" }, "chain": { "type": "string" }, "score": { "type": "number" }, "token": { "type": "string" }, "checks": { "type": "object" }, "symbol": { "type": "string" }, "reasons": { "type": "array" }, "verdict": { "type": "string" }, "confidence": { "type": "string" } } } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "name": "Brett", "tier": "quick", "chain": "base", "score": 97, "token": "0x532f27101965dd16442e59d40670faf5ebb142e4", "checks": { "age": { "days": 968, "source": "first DEX pool (DexScreener)", "created_at": "2024-02-27T00:00:00.000Z" }, "owner": { "address": "0x0000000000000000000000000000000000000000", "renounced": true, "is_contract": false }, "proxy": { "type": null, "upgradeable": false }, "powers": { "fees": [], "mint": [], "pause": [], "limits": [], "source": "verified ABI (sourcify)", "balance": [], "trading": [], "upgrade": [], "blacklist": [], "access_control": false }, "holders": { "count": 909566, "source": "GeckoTerminal", "top10_pct": 32.6, "in_pools_pct": 1.7, "top10_ex_pools_est_pct": 30.9 }, "contract": { "verified": true, "verified_by": "Sourcify" }, "liquidity": { "lp": null, "usd": 721405, "pools": 1, "main_pool": { "dex": "aerodrome", "quote": "WETH" } }, "sellability": { "dex": "aerodrome", "buy_ok": true, "sell_ok": true, "pool_type": "v3", "simulated": true, "buy_tax_pct": 0, "transfer_ok": true, "sell_tax_pct": 0, "transfer_tax_pct": 0, "round_trip_loss_pct": 0.42 } }, "symbol": "BRETT", "reasons": [ { "code": "top10", "text": "Top 10 holders own 30.9% (estimate excluding pools and burn).", "severity": "info" }, { "code": "sellable", "text": "Simulated buy and sell both worked with no token tax (round trip lost 0.42% to pool/hook fees and price impact).", "severity": "good" }, { "code": "renounced", "text": "Ownership renounced.", "severity": "good" }, { "code": "verified", "text": "Source verified (Sourcify).", "severity": "good" } ], "verdict": "SAFE", "confidence": "high" } } ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/tokenverdict-quick-erc-20-token-safety-checker-9f2bfed5/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from api.youraitools.co](https://www.zero.xyz/host/api.youraitools.co/llms.txt)
