Token Verdict
by GadgetHumans API in Onchain & crypto
Use when an agent needs a risk verdict on a Base token contract before buying, routing, swapping or holding it. Send a Base token address, get a scored verdict: honeypot check, buy and sell tax, mint and owner privileges, verified-source status, holder count, live liquidity and 24h volume, a 0-100 safety score with explicit red flags, and a one-line summary. Cheaper than one wrong trade. Poll it: echo the returned watch.change_token back as since=<token> to get ONLY the fields that moved (safety score, honeypot, taxes, mint/owner privileges, liquidity, holders, price) - a pre-trade gate to call before every trade.

Send it back to receive ONLY the fields that changed since that snapshot (changed: [{field, from, to}], unchanged: true|false) plus a fresh change_token - so an agent can poll this as a pre-trade gate before every trade instead of re-… |
