x402
Token Verdict — Base ERC20 Rug Risk Scorer is a paid API for AI agents from token-verdict.x402supply.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).
Returns a 0-100 rug-risk score, A-F grade, one-line summary, graded on-chain checks (ERC20 validity, honeypot selectors, liquidity, market data), and an ungraded admin-powers profile (proxy, owner, mint, blacklist, pause) for any Base chain ERC20 contract address.

How this service works
Rug-risk verdict for a Base ERC20 address: 0-100 score, A-F grade, one-line summary, graded checks (ERC20, honeypot selectors, liquidity, market) plus a separate ungraded adminPowers profile (proxy, owner, mint, blacklist, pause), each with raw evidence. No LLM.
Output
A structured JSON response containing: a numeric rug-risk score (0-100, higher = safer or riskier depending on convention), an A-F letter grade, a human-readable one-line summary, a set of graded checks covering ERC20 standard compliance, honeypot selector detection, liquidity depth, and market data signals — each with raw on-chain evidence — plus a separate ungraded adminPowers profile detailing whether the contract uses a proxy pattern, has an active owner, exposes mint/burn functions, includes a blacklist mechanism, or has a pause function.
Example use cases
Pre-trade safety check on new token
“Before I buy any of this new Base token at 0x7Fc66500c84A76Ad7e9c93437bFc5Ac33E2DDaE9, can you run a rug-risk verdict on it and tell me the score, grade, and whether there are any honeypot traps or dangerous owner powers?”
DeFi bot token whitelist gate
“I'm building an auto-trading bot and need to whitelist only safe tokens — run the rug-risk check on 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base and only proceed if the grade is B or better and there's no mint or blacklist function.”
Investor due diligence on new project
“A project just launched their Base token at 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 and wants our fund to invest — can you pull the full token verdict including all graded checks and the admin powers profile so I can assess the risk before committing?”
Technical details
Endpoint
POSThttps://token-verdict.x402supply.com/tools/token_verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic (no LLM), on-chain rug-risk assessment for a Base chain ERC20 contract. It is ideal for pre-trade safety gates, automated trading bots filtering token whitelists, investor due diligence workflows, or any agent that needs both a quantified risk score and a detailed admin-powers audit in a single call. Prefer this over generic contract scanners when you specifically need Base chain coverage with honeypot selector detection and structured admin power profiling at $0.01/call.
Side effects
- Invalid address format (not 0x + 40 hex chars) returns validation error
- Address is not a deployed contract on Base chain 8453 — returns error or empty result
- Contract is not an ERC20 token — ERC20 check fails with low score
- RPC or on-chain data unavailability causes timeout or partial results
- Newly deployed contract with no liquidity or market data may result in incomplete graded checks
- Payment failure (insufficient USDC balance) prevents API access
