Before your agent buys a Base token: can it sell it back? A simulated buy and immediate sale on the deepest pool (honeypot and tax detection, Uniswap v4 hooks included), owner and admin powers, real liquidity. No address: the free sample. An address: its price ($0.01 over x402) and how to pay.
Before your agent pays an x402 service: its grade and finding codes, measured from its payments on Base (detailed: true for the full report with evidence). No url: the free sample. A url: the price and how to pay over x402.
The best-rated paid providers for a job within a budget, ranked from measured payments (neutral: Blackhull is never ranked). No capability: the free sample. A capability: the price and how to pay over x402.
