Api Endpoint

Flow

Use when an agent is about to approve, buy, or first interact with an unfamiliar Base token or contract and needs a safety verdict before risking funds. Flow contract safety verification: send a token or contract address on Base and get a verdict (safe|caution|danger), a 0-100 safety score, the red flags found, and plain-English agent advice (APPROVE / REVIEW_MANUALLY / DO_NOT_APPROVE).
