# Venice

> Private AI inference through the Venice API with optional Base x402 wallet funding through Base MCP.

Venice is a privacy-focused OpenAI-compatible AI API for text, image, audio, video, embeddings, and web/search tools. The plugin uses normal HTTPS requests for inference, and uses Base MCP for wallet-authenticated x402 sign-in and USDC top-ups on Base.

**Chain:** Base mainnet for x402 wallet funding.

**Operations:** model discovery, chat or response inference, image generation, API-key calls, SIWX wallet auth, x402 balance checks, transaction history, and USDC top-ups.

<Tip>
  **SIWE/SIWX and paid calls.** Venice can use a user-provided API key or a Base-wallet x402 path. The wallet path signs an exact message with Base MCP `sign`; paid top-ups are irreversible and should match the latest Venice payment requirement.
</Tip>

## Try it

```text Private summary theme={null}
Use Venice to summarize this with a private model
```

```text Top up theme={null}
Top up my Venice x402 balance with 5 USDC on Base
```

```text Image theme={null}
Generate an image with Venice using a cinematic style
```

## Pattern

Normal API-key inference does not use a Base MCP submission tool. The assistant sends HTTPS requests to Venice with the bearer token. For x402 wallet auth, Base MCP `sign` signs the exact SIWX/SIWE message, and the assistant sends the resulting base64 payload in `SIGN-IN-WITH-X`.

For x402 top-ups, the assistant asks Venice for the current payment requirement, selects the Base USDC option, pays through the Base MCP x402 tool catalog, and verifies the balance after approval.
