• x402_bazaar_token_verdict_v2__base_token_verdict_v3 read-only

  Token Risk Report: AI verdict on a Base token contract -- grade, red flags, on-chain facts. Not financial advice. Returns: an AI-written token verdict on one token contract: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the contract's own state), a one-liner and a roast, and the facts read: code size, name, symbol, decimals, supply, owner(), proxy slots; plus the deepest Uniswap V3 pool's USD price and depth. No holders, no safety or legitimacy call. GET https://api.arysphere.com/v1/ventures/x402_bazaar_token_verdict_v2/base_token_verdict_v3. Same payment terms as that HTTP route. Call once with no payment. The result is the payment terms. Retry the same call with the signed payment at _meta["x402/payment"].
