How this service works
Send a token contract address, get a risk verdict. Returns SOLID / CAUTION / DANGER with a 0-100 score, six weighted market-structure signals (liquidity depth, volume churn, sell pressure, price action, trader breadth, pair age) and a written analyst take. Built for AI agents screening tokens before touching them. Use this when an agent is about to buy, swap, or route funds into a token and needs a fast risk screen first.
Output
A JSON object containing: the token identity (address, symbol, name, chain), a verdict enum (SOLID, CAUTION, or DANGER), a numeric risk score from 0 (safest) to 100 (riskiest), an array of six weighted market-structure signals each with a name, score, weight, and detail string (covering liquidity depth, volume churn, sell pressure, price action, trader breadth, and pair age), a written analyst take summarizing the market situation, and live market data including price, liquidity, 24h volume, 24h price change, buy/sell transaction counts, the DEX name, and a DexScreener pair URL.
Example use cases
Pre-swap token safety check
“Before my DeFi agent swaps 500 USDC into that new Ethereum token at 0xabc123…, can you get me a risk verdict on it — I need to know if it's SOLID, CAUTION, or DANGER and what the liquidity and sell pressure signals look like?”
Solana memecoin screening
“There's a Solana token at address So11111111111111111111111111111111111111112 that's been getting hyped — can you screen it for risk and tell me the score and the analyst take before I touch it?”
Autonomous agent pre-trade guardrail
“My trading bot is about to route funds into a Base token at 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — run a risk verdict on it first and block the trade if it comes back DANGER.”
Technical details
Endpoint
POSThttps://token-verdict-production.up.railway.app/v1/verdict?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fast, pre-trade risk screen on a specific token contract before executing a swap, buy, or fund routing action. It is purpose-built for agentic workflows — returning a machine-readable verdict enum alongside a numeric score and six structured signals, making it easy to build automated guardrails. Prefer this over generic token info APIs when you need an opinionated risk assessment rather than raw market data, and when you need a written analyst take to surface to a human-in-the-loop. Best for Base, Ethereum, and Solana tokens with live DEX pairs.
Side effects
- Invalid or unrecognized contract address returns an error
- Token not found on specified chain (wrong chain label for the address)
- Token has no DEX pair data — insufficient market data to score
- Chain enum value not matching supported values (base, ethereum, solana)
- Network timeout if on-chain data sources are slow to respond
- Payment failure or insufficient USDC balance (x402 payment required per call)
