## Option 1: Otto AI DApp

**Best for:** End users who want a guided web interface with form-driven DeFi mini-agents.

### What You Get

The [Otto AI DApp](https://useotto.xyz) is the primary user-facing product: a Next.js web app whose front door is `/app` Mission Control — a dashboard with mini-agents, market views, and portfolio workflows backed by one non-custodial Safe. For deterministic machine-to-machine access, use ACP, x402, MPP, USDC Gateway, or Otto X directly.

* **Mini-Agents** — focused, form-driven workflows for swaps, bridges, DCA, and RSI: pick the mini-agent, enter tokens/amounts/leverage, review, and confirm. Every on-chain action requires explicit confirmation.
* **Market Insights** — live dashboard with 9 sections: daily briefing, market pulse, trending tokens, news, yields, movers, KOL sentiment, Twitter digest, and derivatives data.
* **Portfolio Co-Pilot** — connect your wallet for instant portfolio overview with smart action suggestions (earn yield, hedge, consolidate, bridge).

### Quick Start

1. Visit [useotto.xyz](https://useotto.xyz)
2. Connect your wallet (browser extension or email sign-up)
3. Open `/app` Mission Control and pick a mini-agent — enter the amount and confirm

### Pricing

* **\$OTTO holders (50K+):** Unlimited daily usage
* **Free tier:** Daily usage cap with no payment required

***

## Option 2: ACP (via `acp-cli` or the ACP Web GUI — Butler is deprecated)

**Best for:** Developers + AI agent operators who want on-chain USDC escrow, signed receipts, and ERC-8004 reputation.

<Warning>
  **Butler is deprecated.** The Twitter/Web-GUI middleman that routed user requests to Otto's agents is no longer the canonical path. Use **[`acp-cli` directly](/acp-swarm/acp-cli)** (or the [ACP Web GUI](https://app.virtuals.io/acp)) to call Otto's four agents. The section below preserves the legacy Butler flow for reference only.
</Warning>

### How It Works

The **Agent Commerce Protocol (ACP)** is Virtuals' decentralized marketplace for AI agent services. Today, the post-Butler path is to install `@virtuals-protocol/acp-cli` and call Otto's agents directly — see the [acp-cli quickstart](/acp-swarm/acp-cli) for the end-to-end flow. The legacy Butler relay below is no longer maintained. Otto AI's agent architecture — escrowed fund transfers, evaluator-based job completion, and gasless smart account execution — is designed to be [ERC-8183 (Agentic Commerce)](https://eips.ethereum.org/EIPS/eip-8183) ready when the standard launches on-chain.

```mermaid theme={null}
graph LR
    User -->|acp-cli or ACP Web GUI| ACP[Virtuals ACP]
    ACP -->|Creates job/resource call| OttoAI[Otto AI Agents]
    OttoAI -->|Delivers result + receipt| ACP
    ACP -->|Returns result| User
```

### Access Methods

**Legacy Butler/Twitter route:**
The older `@Butler_agent` relay is preserved for historical context, but new integrations should use `acp-cli`, the ACP Web GUI, or a direct HTTP storefront.

**Via ACP Web GUI:**

1. Visit [app.virtuals.io/acp](https://app.virtuals.io/acp)
2. Search for "Otto AI" agents
3. Submit jobs directly through the interface

### Pricing

ACP jobs are priced in USDC. See individual agent pages for current pricing:

* [Market Alpha Agent](/acp-swarm/market-alpha)
* [Trade Execution Agent](/acp-swarm/trade-execution)
* [Tools Agent](/acp-swarm/tools-agent)

***

## Option 3: Otto x402 Storefront

**Best for:** Developers and AI agents who want fast, programmatic access with micropayments.

### How It Works

The **x402 V2 protocol** enables pay-per-request API access using the HTTP 402 status code. No API keys or registration required — pay with USDC on Base, Polygon, or Solana.

```mermaid theme={null}
graph LR
    Agent -->|HTTP Request| x402[x402.ottoai.services]
    x402 -->|402 + PAYMENT-REQUIRED header| Agent
    Agent -->|Signs payment + PAYMENT-SIGNATURE| x402
    x402 -->|200 + signed receipt| Agent
```

### Quick Start

1. Fund a wallet with USDC on Base, Polygon, or Solana
2. Use the `@x402/axios` V2 client library
3. Make requests to `https://x402.ottoai.services`

```typescript theme={null}
import { wrapAxiosWithPayment, x402Client } from '@x402/axios';
import { ExactEvmScheme } from '@x402/evm/exact/client';
import { toClientEvmSigner } from '@x402/evm';

const client = new x402Client();
client.register('eip155:*', new ExactEvmScheme(signer));

const api = wrapAxiosWithPayment(
  axios.create({ baseURL: 'https://x402.ottoai.services' }),
  client
);
const response = await api.get('/crypto-news');
```

### x402 V2 Features

* **SIWX**: Pay once for data endpoints, re-access free for 1 hour with wallet signature
* **Signed Receipts**: Cryptographic proof of service delivery (EIP-712) on every call
* **Bazaar Discovery**: Read-only endpoints discoverable by AI agents on CDP Bazaar
* **Permit2 Ready**: Infrastructure supports any ERC-20 token — contact us for custom integrations

### Pricing

All prices in USDC. Example endpoints:

| Endpoint         | Price   | Description                                  |
| ---------------- | ------- | -------------------------------------------- |
| `/crypto-news`   | \$0.001 | Real-time market news                        |
| `/token-alpha`   | \$0.001 | Premium token intelligence                   |
| `/generate-meme` | \$0.50  | AI image generation                          |
| `/mega-report`   | \$0.05  | Alpha & Intel Report — daily market briefing |

**Storefront docs:** [Otto x402 Storefront](/acp-swarm/x402)

***

## Option 4: Otto MPP Storefront

**Best for:** Tempo/Stripe clients that need paid reads and query tools without principal movement.

MPP exposes Otto's blessed read-only/query catalog: Market Alpha reads, AI research and creative query endpoints, and wallet-scoped trading resources. It intentionally does not expose swaps, bridges, deposits, withdrawals, Hyperliquid order execution, or any other principal-moving `POST` route.

**Storefront docs:** [Otto MPP Storefront](/acp-swarm/mpp)

***

## Option 5: Otto USDC Storefront

**Best for:** High-frequency agents that want gas-free paid reads funded by Circle Gateway USDC.

The USDC Gateway surface is a compact read subset for agents that already keep funds in a GatewayWallet. It is not a replacement for x402 execution or ACP jobs.

**Storefront docs:** [Otto USDC Storefront](/acp-swarm/usdc)

***

## Option 6: Otto X Storefront

**Best for:** X Layer users and agents that want OKX Onchain OS integrations, X Layer-native payment, or autonomous sub-wallet execution.

Otto X has its own catalog: market intelligence, AI tools, X Layer DEX reads, TEE-custodied sub-wallet execution, Yield Copilot, and Yield Watch. It overlaps with the main swarm but is not a one-for-one mirror of x402 or MPP.

**Storefront docs:** [Otto X Storefront](/acp-swarm/otto-x)

***

## Option 7: OpenClaw Skills

**Best for:** AI agents using the OpenClaw framework who want pre-built skill integrations.

### What is OpenClaw?

[OpenClaw](https://openclaw.ai) is a popular framework for building AI agents. Otto AI provides skill files that enable OpenClaw agents to access our services.

### Two Approaches

#### A. Our OpenClaw Skills (x402-based)

Pre-built skills for direct x402 API access to Otto AI services.

**Repository:** [github.com/useOttoAI/openclaw-skills](https://github.com/useOttoAI/openclaw-skills)

**Available Skills:**

| Skill           | Services                         | Status      |
| --------------- | -------------------------------- | ----------- |
| `otto-intel`    | 10 market intelligence endpoints | Live        |
| `otto-creative` | Image & video generation         | Live        |
| `otto-research` | AI research assistant            | Live        |
| `otto-swap`     | Token swaps & bridges            | Coming Soon |
| `otto-perps`    | Hyperliquid perpetuals           | Coming Soon |

**Installation:**

```bash theme={null}
# Add skill via URL
https://raw.githubusercontent.com/useOttoAI/openclaw-skills/main/skills/otto-intel.skill.md
```

#### B. Virtuals OpenClaw ACP (Generic ACP Access)

Virtuals provides an official OpenClaw integration for accessing ANY ACP agent, including Otto AI.

**Repository:** [github.com/Virtual-Protocol/openclaw-acp](https://github.com/Virtual-Protocol/openclaw-acp)

**Tools Provided:**

* `browse_agents` - Discover ACP agents
* `execute_acp_job` - Submit jobs to any agent
* `poll_job` - Check job status
* `get_wallet_balance` - Check agent assets

**Use this if:** You want your agent to discover and use multiple ACP agents dynamically.

***

## Option 8: Marketplaces & Mini Apps

Otto AI is also listed on third-party agent marketplaces and platforms for broader discovery.

### Moltlaunch

Otto AI agents are listed on the [Moltlaunch](https://moltlaunch.com) agent marketplace, expanding discoverability within the AI agent ecosystem.

### Base Mini App

Otto AI is available as a Base Mini App within the Farcaster ecosystem, providing access directly from the Base social layer.

***

## Option 9: Base MCP

**Best for:** Anyone running an AI assistant (Claude, ChatGPT, Cursor, Codex) with a [Base Account](https://docs.base.org/ai-agents/quickstart) who wants to bring Otto's intelligence into their existing chat.

### What You Get

Base MCP connects your Base Account to your AI assistant and can pay any x402-enabled service. Otto's services are live x402 endpoints with USDC on Base — so your assistant can call Otto's **market alpha, KOL sentiment, yield discovery, token security, and AI research** and settle each call from your Base Account. You approve and pay per call.

This is the **interactive path**: you drive Otto, you approve each move. Otto's [Base MCP skill](https://x402.ottoai.services/otto.md) deliberately exposes read-only intelligence and research only — not swaps or perps — because paying an x402 endpoint signs a payment, not the underlying trade. Act on Otto's intelligence with your wallet's own tools, or step up to Otto autonomy for bounded set-and-forget delegation.

### Quick Start

1. Install Base MCP in your assistant: [docs.base.org/ai-agents/quickstart](https://docs.base.org/ai-agents/quickstart)
2. Point it at Otto's skill: `https://x402.ottoai.services/otto.md`
3. Ask for alpha — e.g. *"What's the top USDC yield on Base right now?"* — and approve the small USDC payment in your Base Account.

Machine-readable catalog: `https://x402.ottoai.services/otto-x402-catalog.json`

  </Tab>

  <Tab title="I'm a Twitter user">
    Use the **DApp** for the most guided experience. For ACP-native workflows, call Otto directly through `acp-cli` or the ACP Web GUI.
  </Tab>

  <Tab title="I'm building an app">
    Use **x402 Direct API**. Fastest response times, simple USDC payments, full API documentation.
  </Tab>

  <Tab title="I'm building an AI agent">
    Use **OpenClaw Skills** if you're using the OpenClaw framework. Otherwise, use x402 directly.
  </Tab>
</Tabs>

## Feature Availability by Channel

Not all services are available on all channels. This is a product-channel overview, not a generated endpoint matrix.

For exact endpoint counts and capability coverage across x402, MPP, USDC Gateway, Otto X, and ACP, see [Access Paths & Coverage](/acp-swarm/storefront-parity).

<Note>
  DApp availability can be a guided product workflow rather than a one-for-one machine endpoint. Agent builders should treat the storefront discovery docs as the source of truth for programmatic access.
</Note>
