Base Token Safety Check
x402
Base Token Safety Check is a paid API for AI agents from aiworker.duckdns.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).
Returns a deterministic risk card for a Base-chain ERC-20 token: contract metadata, ownership, holders, DEX trading pairs, honeypot simulation result, risk flags, and a 0-100 safety score.

How this service works
Deterministic-first data for agents, paid per call in USDC over x402 v2: DeFi yields, Base token and wallet cards, Polymarket odds and backtests, news, fact checks, cited briefs. 20 routes, $0.005-$1
Output
A structured safety card including: contract name/symbol/type, owner and admin addresses, top token holders and concentration metrics, active DEX trading pairs and liquidity, honeypot simulation pass/fail (buy and sell round-trip), a list of rule-based risk flags (e.g. mint authority, proxy contract, low liquidity), and a composite 0-100 safety score. No LLM-generated opinion — all outputs are deterministic.
Example use cases
Memecoin rug-pull pre-check
“Before I ape into this new Base memecoin at 0x4e9ce36e442e55ecd9025b9a6e0d88485d628a67, can you check if it's a honeypot, who owns the contract, and what the overall safety score is?”
DeFi bot token gating
“My trading bot is about to swap into a token at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base — run a full safety card on it first and block the trade if the score is below 60 or it fails the sell simulation.”
Holder concentration audit
“Can you pull the safety report for Base token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me if ownership is concentrated in a few wallets or if there are any control flags I should worry about?”
Technical details
Endpoint
POSThttps://aiworker.duckdns.org/v1/check/tokenWhen to prefer
Choose this endpoint when you need a fast, deterministic, rule-based safety assessment of a Base-chain token before trading or investing — especially for honeypot detection, ownership analysis, and DEX liquidity checks. Prefer this over LLM-based analysis when you need reproducible, verifiable risk scoring with no hallucination risk. Best for Base EVM tokens; not suitable for tokens on other chains.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Token not deployed on Base chain causes lookup failure
- Contract deployed but not yet indexed by Blockscout may return incomplete metadata
- No DEX pairs found if token has no liquidity
- Honeypot simulation may fail if the token has unusual transfer logic
- Rate limiting or provider outages from Blockscout, Honeypot.is, or Base RPC may cause partial results
