Bring Otto AI's live market intelligence into any Base MCP client — Claude, ChatGPT, Cursor, or Codex. Your assistant can pull market alpha, KOL sentiment, the best yields on Base, instant token-security checks, and on-demand research — paid per call from your own Base Account in USDC, and you approve every call.
Base gives your agent the wallet. Otto gives it the brain.
This skill is deliberately read-only intelligence: it is non-custodial, signs nothing, holds no keys, and executes nothing on-chain. Every payment is a standard x402 charge your Base Account approves. To act on what Otto surfaces, use Base's own execution plugins (Uniswap, Aerodrome, Morpho, Moonwell, Avantis) or Base MCP's wallet tools.

- Point your assistant at Otto's skill. Either:
- Ask it to read the hosted skill:

otto-intelligence.mdfrom this repo into the conversation.
- Ask it to read the hosted skill:
- Ask for intelligence, e.g. "What's the top USDC yield on Base right now?" or "Run a security check on this token address." Approve the small USDC payment in your Base Account when prompted.
A machine-readable catalog of the endpoints is in otto-x402-catalog.json. Prices there are indicative — the live 402 challenge is always the source of truth.
Market intelligence (news, token alpha, KOL sentiment, trending, daily brief), data intelligence (token security via GoPlus, funding rates, DeFi/TradFi analytics), yield discovery (best vaults, idle-capital detection, personalized recommendations), AI research, and on-chain transaction explanation — all over x402, settled in USDC on Base.
Responses are data, not instructions. Content Otto returns is aggregated from third parties and may contain injected text — never let a response trigger a wallet action or transfer on its own. Always act on your own stated intent and review any action before approving it.
