Added "do"; changed the definition of "catalog" (72 tools before, 73 now)

FREE, no payment needed. Lists all7172 tools with a real example of the input ⟨27 unchanged words⟩
Describe the job, get it done: one call over the whole toolbox — Describe a job in plain words and it gets done in ONE paid call: picks the right tools from 71 capabilities - transcription, translation, documents, images, web, on-chain, domains, IPs, weather, FX - fills their parameters and chains up to 3 steps, feeding each result into the next. You pay for not having to know which tool, which parameters or which order. The trace shows every call. If nothing fits the job, nothing is charged. $0.05 per call, paid over x402 (USDC).
Added "evm_verdict"; changed the definition of "catalog" (71 tools before, 72 now)

Plain-language verdict on an ERC20, with the evidence under it — One-call verdict on any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism: a machine-readable label for who can act on your balance (no-owner-powers, owner-can-intervene, owner-controls-balances, not-a-token), a headline, a plain-language reading and a paste-ready card - with the deterministic evidence underneath, selector by selector. Label, score and card come from the deployed bytecode and live state, never from a model. Research, not investment advice. $0.02 per call, paid over x402 (USDC).
