x402
Fetchgate Token Risk Check is a paid API for AI agents from fetchgate.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).
Checks a Base network token contract address for risk signals (ERC-20 metadata, upgradeable proxy, mint/pause/blacklist/fee traps, DEX liquidity) and returns an ok/caution/avoid verdict with reasons.

How this service works
Base token risk check before a swap: send a token contract address, get ok / caution / avoid with reasons. Reads the contract (ERC-20 metadata, owner, upgradeable proxy, mint / pause / blacklist / fee selectors in bytecode) and its DEX liquidity (Uniswap + Aerodrome pools, read on-chain). Deterministic, no LLM.
Output
Returns a risk verdict of 'ok', 'caution', or 'avoid' along with structured reasons explaining the finding — covering ERC-20 metadata, whether the contract is an upgradeable proxy, presence of mint/pause/blacklist/fee bytecode selectors, and on-chain DEX pool liquidity from Uniswap and Aerodrome on Base.
Example use cases
Pre-swap safety check for DeFi agent
“I'm about to buy some tokens at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you check if it's safe or if there are any red flags like blacklists or mint functions before I swap?”
Rug pull detection for new token
“This new token on Base just launched at 0x4200000000000000000000000000000000000006 — can you check whether the contract is upgradeable, has a pause function, or any other honeypot traps?”
Liquidity verification before trading
“Does the token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base have real Uniswap or Aerodrome liquidity, or is it a low-liquidity trap? Give me a full risk verdict.”
Technical details
Endpoint
GEThttps://fetchgate.dev/v1/token/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to execute or recommend a token swap on Base and needs a fast, deterministic, no-LLM safety gate. Ideal for DeFi automation workflows where you want to block honeypots, rug pulls, or high-risk contracts before committing funds. Prefer this over general-purpose blockchain explorers when you specifically need an opinionated ok/caution/avoid verdict with actionable reasons rather than raw contract data.
Side effects
- Invalid or non-existent contract address returns an error
- Contract not deployed on Base network
- Address is an EOA, not a contract
- RPC timeout reading on-chain data
- Token has no DEX liquidity pools (may return caution with zero-liquidity reason)
- Malformed address format (non-checksummed or wrong length)
