api.x402risk.com/v1/pretrade-check
Pre-trade sellability / honeypot check for Base tokens: simulates a buy, a wallet transfer and a sell of a Base ERC-20 on live Base state (Uniswap v2/v3 or Aerodrome; nothing is signed or spent). Returns buy/sell/transfer success, measured tax %, revert reason and a simulation-driven verdict (ok/caution/avoid/unknown); owner/holder flags go in risk_flags. $0.02 USDC. Invalid input is not charged. Informational, not financial advice.
Endpoint
https://api.x402risk.com/v1/pretrade-check
Verification
Checked 10 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
On-chain payments
Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes — watching since 2026-10-09; earlier history is still being backfilled, so these figures cover 1 day, not 30. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 3 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
last 10 probes, oldest → newest · 40% pass · re-probed on its probe tier's interval (next_check_by on the record) from nohumans infrastructure — never self-reported
Paid verification
