ERC-20 Token Risk Analyzer (x402)
x402
ERC-20 Token Risk Analyzer (x402) is a paid API for AI agents from freetier-agent-api.pages.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).
Analyzes an ERC-20 token contract address on Base or Ethereum and returns a risk score, flags, liquidity data, and a safety verdict using on-chain heuristics.

How this service works
Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.
Output
Returns a JSON object with the token's name, symbol, chain, contract address, a numeric risk score (0–100), a verdict string (e.g. 'no_major_red_flags_found'), an array of risk flags with severity levels and evidence, liquidity pool data (pools, approximate liquidity in USD, burned percentage, owner share), whether the contract is a proxy, whether the owner is renounced, total supply, decimals, and a disclaimer. Also includes the RPC used, the block at which it was checked, and a list of checks not performed (e.g. honeypot sell simulation).
Example use cases
Pre-trade token safety check
“Before I buy this token, can you check the risk score and any flags for contract 0x4ed4e862860bed51a9570b96d89af5e1b0efefed on Base? I want to know if the owner is renounced and whether liquidity looks healthy.”
DeFi research bot token screening
“Scan the Ethereum token at 0xc18360217d8f7ab5e7c516566761ea12ce7f9d72 for rug pull signals — I need the verdict, risk score, and any flags about pausing or admin controls.”
Portfolio watchlist risk audit
“Run a risk assessment on these two Base tokens — 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 and 0x4ed4e862860bed51a9570b96d89af5e1b0efefed — and summarize the risk scores and any high or medium severity flags for each.”
Technical details
Endpoint
GEThttps://freetier-agent-api.pages.dev/api/token-risk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call (no signup) on-chain token risk assessment for Base or Ethereum ERC-20 tokens. It is ideal for AI agents that need to programmatically screen tokens before trades, surface rug-pull signals, or audit token contracts without setting up API keys. Prefer this over manual block explorer inspection or expensive subscription risk APIs when operating in an autonomous, low-friction crypto research workflow.
Side effects
- Invalid or non-contract address returns isContract: false or an error
- Unsupported chain value returns a validation error
- Token with no on-chain liquidity may return null liquidity fields
- Payment failure via x402 (insufficient USDC balance) results in 402 response
- RPC node timeout or unavailability may cause partial or failed response
- Contract with obfuscated bytecode may result in incomplete flag detection
