Rug Monitor

by Rug Early-Warning Monitor in Developer tools

x402 APIPassing, checked 4 h ago

Pay once to watch a Base token's liquidity. We snapshot a baseline and, on each monitor run, POST your webhook if liquidity collapses (a liquidity pull — the actual moment of a rug). Not price moving — the pool being drained out from under you. Expires after 30 days.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.

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/rug-monitor?dropPct=50&token=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed'

# 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/rug-monitor?dropPct=50&token=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed' \
