Proxy Token Watch

by Token Risk Monitor in Onchain & crypto

x402 APIPassing, checked 2 h ago

Token monitoring for trading agents: re-checks a token on-chain and reports only what changed since your last call: grade downgrade (A to F), honeypot or sell tax appearing, new risk flags (mint, blacklist, owner powers), price and liquidity moves above your threshold (liquidity pulls, rug signals) and holder concentration shifts, with an alert_level (none, medium, high). Same checks as token-verdict and token-security, computed by us on the blockchain.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.008.

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-watch' \

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
