Sellability

x402 APIPassing, checked 4 h ago

The hard honeypot question, answered three ways: security simulation (honeypot, cannot-sell-all, sell/buy tax, transfer-pausable), a LIVE transfer simulation we run ourselves from a real holder (reverts/taxed?), and exit liquidity. Returns a hard canSell verdict with reasons. Selling is where rugs hide — check before you buy.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.08.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/sellability?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed&size=5000'

# 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://402.com.tr/api/x402/sellability?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed&size=5000' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
