Base Token Verdict

by heb-utils-x402.hebutils-api.workers.dev in Onchain & crypto

x402 APIPassing, checked 2 h ago

Check if a token on Base looks risky: plain-language heuristic screen of a token contract for admin-control signals (upgradeable proxy, active owner, mint, pause, blacklist, fee setters), with a one-line headline, signal count and shareable summary. Pass the token contract address. Heuristic bytecode screen, not an audit, not advice.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://heb-utils-x402.hebutils-api.workers.dev/base-token-verdict?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913'

# 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://heb-utils-x402.hebutils-api.workers.dev/base-token-verdict?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913' \
