Token Honeypot

by Token Honeypot & Sell Tax Check in Onchain & crypto

x402 APIPassing, checked 4 h ago

Honeypot check for a Base token: can you sell it after you buy? Simulates a buy and a sell on its Uniswap v2, v3 or v4 or Aerodrome pool and returns sellable, high_tax, honeypot or unknown, both taxes and the pool, plus the owner powers in its code, proxies included (mint, blacklist, pause, fee changes, upgrade), and whether one key holds them. A simulation at one block, not an audit; unknown, never a guess, and no charge if our node fails. Free: GET /v1/token. Trial: /v1/trial.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.010004.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://trust-agent.io/v1/token/honeypot?address=0x940181a94A35A4569E4529A3CDfB74e38FD98631&chain=base'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://trust-agent.io/v1/token/honeypot?address=0x940181a94A35A4569E4529A3CDfB74e38FD98631&chain=base' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
