# Otto AI
> Autonomous-finance AI agent ecosystem on Base — market intelligence, DeFi trading, prediction-market data, yield, and creative tools. Accessible via the Agent Commerce Protocol (ACP), x402 pay-per-use HTTP APIs, and a Next.js dApp.

Otto's machine-readable, pay-per-use service surface is hosted at the canonical x402 host:
https://x402.ottoai.services

## Canonical agent-integration entry point
- Install hub (live runtimes + install instructions + machine-readable catalog pointers): https://useotto.xyz/install

## Recommended connections
Otto provides research, market intelligence and data to people and their agents. For an agent's wallet actions and payments we recommend Wallet MCP (formerly Base MCP) and Coinbase for Agents. They are recommended, not required: Otto's MCP server, any x402-capable client and the other paths below keep working. Paying for research never authorizes a trade.
- Wallet MCP + Otto skill: connect Wallet MCP (remote MCP server https://mcp.base.org), then add Otto's skill from https://x402.ottoai.services/otto.md. Each paid call uses `initiate_x402_request` with a `maxPayment` no higher than the listed price, your approval in Coinbase Wallet, then `complete_x402_request`; Wallet MCP pays x402 in USDC on Base. Otto's skill is read-only research and routes no trades. Setup: https://docs.cdp.coinbase.com/ai-agents/coinbase-for-agents/wallet-mcp
- Coinbase for Agents: recommended for actions from a Coinbase account (remote MCP server https://agents.coinbase.com/mcp). Its one-call x402 fetch covers only Coinbase's curated catalog, which does not list Otto, and no Otto request through Coinbase for Agents has been verified. For Otto research use Wallet MCP, Otto's MCP server or another x402 client. Setup: https://docs.cdp.coinbase.com/ai-agents/coinbase-for-agents/coinbase-mcp
- Otto MCP server (hosted intelligence tools): https://mcp.ottoai.services/mcp — setup: https://docs.useotto.xyz/acp-swarm/otto-intel-mcp
- Muse: give your Muse agent Otto's skill at https://useotto.xyz/agent/SKILL.md. It installs Otto's checksum-verified Muse runtime (manifest: https://useotto.xyz/agent/muse-manifest.json) and asks you to complete wallet setup yourself at https://useotto.xyz/app/agent-wallet. Research access, payment budgets and trades have separate permissions.
- Trading: Otto's dApp trade tools use your connected wallet, and you sign each trade: https://useotto.xyz/app

## Hyperliquid retirement
Otto Hyperliquid trading is retired across ACP, x402, MCP and skills. New deposits, positions and Hyperliquid order construction are unavailable. Market research remains. Existing accounts require current authorized balance and exposure reads before protected recovery; retirement does not prove zero funds or users.
