# LLM Config

### LLM provider configuration, key management, and x402 micropayment routing via ClawRouter.

## LLM & Payments

Molt.id Multiclaw Service supports multiple LLM providers with a priority-based key resolution system. Users can bring their own API keys, use platform-provided global keys, or pay per request via x402 micropayments through ClawRouter.

{% hint style="info" %}
Platform-provided global LLM keys are **rate-limited** and shared across all users. Please expect occasional downtime or slow responses during high usage. We will introduce a daily credits system soon. For the best experience, **Bring Your Own Key (BYOK)** is strongly recommended as your primary option
{% endhint %}

### Supported Providers

| Provider       | Models                            |
| -------------- | --------------------------------- |
| **Anthropic**  | Claude Sonnet, Haiku, Opus        |
| **OpenAI**     | GPT-4o, GPT-4o-mini               |
| **OpenRouter** | 100+ models via OpenRouter proxy  |
| **ClawRouter** | 30+ models via x402 micropayments |

***

### Key Priority

Keys are resolved in this order for each user:

```
User's own key
  → Platform global key
  → Not available
```

This means:

* **Global keys** set by the platform work for all users by default
* **Per-user keys** override global keys when set
* Users who bring their own API keys get billed directly by the provider

***

### Default Model Selection

When a container starts, the default model is automatically selected based on which providers have keys available:

```
ClawRouter available? → blockrun/auto (cheapest, smart routing)
  → OpenRouter available? → openrouter/anthropic/claude-sonnet-4-5
  → Anthropic available? → anthropic/claude-sonnet-4-5
  → OpenAI available? → openai/gpt-4o
```

***

### Key Security

* Keys are **never exposed** to users through any endpoint
* API responses show only the first 8 characters (redacted)
* Inside containers, keys are stored in isolated files with restricted permissions
* Sensitive files are **excluded from snapshots** — always written fresh on startup

***

### ClawRouter (x402 Micropayments)

ClawRouter is an x402 micropayment-based LLM proxy that runs inside each container. It lets users access 30+ LLM models without needing individual API keys — costs are paid from a Solana wallet via HTTP 402 micropayments.

#### How It Works

```
OpenClaw → ClawRouter (local proxy) → x402 payment → LLM Provider
```

1. OpenClaw sends a standard OpenAI-compatible request to ClawRouter
2. ClawRouter routes the request to the cheapest available provider
3. The provider responds with HTTP 402 (Payment Required) + an x402 invoice
4. ClawRouter pays the invoice from the configured Solana wallet
5. Provider returns the LLM response
6. ClawRouter forwards it back to OpenClaw

#### Available Models

The `blockrun/auto` model uses smart routing to pick the cheapest model. Individual models are also available:

* `blockrun/anthropic/claude-sonnet-4`
* `blockrun/anthropic/claude-haiku-4.5`
* `blockrun/openai/gpt-4o`
* `blockrun/openai/gpt-4o-mini`
* `blockrun/google/gemini-2.5-flash`
* `blockrun/deepseek/deepseek-chat`
* And 20+ more

#### Wallet Key Priority

The wallet key used for x402 payments follows the same priority as LLM keys:

```
Per-user wallet key → Platform global wallet key → Not available
```

The wallet key is written securely inside the container on startup and is **never** exposed to users or included in snapshots.
