Proxy Token Simulate

by Honeypot Test by Real Buy and Se in Onchain & crypto

x402 APIPassing, checked 1 h ago

Replays a real buy and sell of the token on chain state and tells you if you can get out again: buy_succeeded, sell_succeeded, buy and sell tax in percent, honeypot reason, estimated round-trip cost in percent and USD for amount_usd, plus the pools used. Use before buying an unknown token or in a trading bot. EVM chains are simulated; Solana returns status not_simulated with authority and pool checks. No liquidity returns status no_liquidity. Cost excludes LP fees and gas.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.012.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agentsvc.io/api/v1/proxy/token-simulate' \
  -H 'content-type: application/json' \
  --data-raw '{"amount_usd":100,"chain":"base","token":"0x532f27101965dd16442E59d40670FaF5eBB142E4"}'

# 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 - -X POST 'https://agentsvc.io/api/v1/proxy/token-simulate' \
  -H 'content-type: application/json' \
  --data-raw '{"amount_usd":100,"chain":"base","token":"0x532f27101965dd16442E59d40670FaF5eBB142E4"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
