# OpenClaw + AI Prime Tech: Self-Hosted Agent on Discounted Claude API 

 A  By [AI Prime Tech](https://aiprimetech.io/)  · AI-assisted    

OpenClaw is one of the most flexible open-source agent frameworks for Claude. It runs locally, supports custom tool definitions, and gives you full visibility into every API call your agent makes. But like any agent that uses Opus-tier reasoning, the API bills add up fast against official Anthropic pricing. 

This guide walks through pointing OpenClaw at the AI Prime Tech gateway — getting you the same Claude models at 70-80% lower cost, while keeping every byte of your agent’s state on your own machine. 

## Why pair OpenClaw with AI Prime Tech 

OpenClaw is genuinely the “do everything locally” answer: agent state, tool definitions, memory, even your environment all stay on disk. But it has to call Claude over the internet for inference. That call is the only thing that costs you money — and it’s exactly what AI Prime Tech makes cheaper. 

You keep:  
- ✅ Full local control of agent code and state 
- ✅ Your custom tool definitions (file system, browser, shell, etc.) 
- ✅ Total visibility into every prompt / completion 
- ✅ No vendor lock-in — switch back to official Anthropic anytime by changing one env var  

You get:  
- 💰 70-80% lower Claude API cost on the same models 
- 💰 Pay-as-you-go billing in USD / crypto, not monthly subscriptions 
- 💰 Free intelligent model routing (Opus/Sonnet/Haiku) handled by the gateway  

## Prerequisites  
- OpenClaw installed and working with the official Anthropic API 
- AI Prime Tech account with credit added ([sign up free](https://aiprimetech.io/register)) 
- API key from your AI Prime Tech dashboard (format: apt-...)  

## Step 1: Generate your AI Prime Tech API key  
- Log in to [aiprimetech.io](https://aiprimetech.io/login) 
- Navigate to API Keys → Create New 
- Name it something memorable (e.g., “openclaw-dev”) 
- Copy the generated key — you’ll only see it once  

## Step 2: Configure OpenClaw to use the gateway 

OpenClaw respects standard Anthropic SDK environment variables. The minimal config: 

```
# ~/.openclaw/config.yaml
provider:
  type: anthropic
  base_url: "https://aiprimetech.io"
  api_key: "${APT_API_KEY}"

models:
  default: claude-sonnet-4-6
  reasoning: claude-opus-4-7
  fast: claude-haiku-4-5
```

Then export your key: 

```
export APT_API_KEY="apt-your-key-here"
```

Or — if you prefer not to change OpenClaw’s config at all — just override the standard env vars: 

```
export ANTHROPIC_API_KEY="apt-your-key-here"
export ANTHROPIC_BASE_URL="https://aiprimetech.io"
```

OpenClaw will pick these up automatically on next launch. 

## Step 3: Test the connection 

```
openclaw test --provider anthropic
```

Expected output: 

```
✓ Provider: anthropic (base: aiprimetech.io)
✓ Auth: OK
✓ Model claude-opus-4-7: 142ms
✓ Model claude-sonnet-4-6: 98ms
✓ Model claude-haiku-4-5: 76ms

All checks passed. Ready to run agents.
```

## Step 4: Run your first agent 

```
openclaw run --task "Review the codebase in ./src and write a one-paragraph architecture summary"
```

You’ll see OpenClaw plan the steps, call aiprimetech.io for each one, and execute tools locally. Token costs appear in your AI Prime Tech dashboard in real time. 

## Smart model assignment per agent role 

OpenClaw lets you assign different models per agent role. This is where you save another 40-60% on top of the gateway discount: 

```
roles:
  planner:
    model: claude-opus-4-7    # only for high-level planning
    max_tokens: 4096
  coder:
    model: claude-sonnet-4-6  # 5x cheaper, excellent code quality
    max_tokens: 8192
  searcher:
    model: claude-haiku-4-5   # 15x cheaper, perfect for tool dispatch
    max_tokens: 2048
```

Most agent loops are 70%+ “searcher” calls. Routing those to Haiku alone cuts spend dramatically without quality loss. 

## Advanced: prompt caching for system prompts 

OpenClaw’s system prompts can be 2000+ tokens. AI Prime Tech supports Anthropic’s prompt caching natively — enable it for 90% off cached content: 

```
provider:
  features:
    prompt_caching: true
    cache_ttl: 3600  # seconds
```

## Monitoring and cost control  
- Set per-key monthly spend caps in the AI Prime Tech dashboard — hard stop, no surprise bills 
- Export your usage logs as CSV for end-of-month accounting 
- Use the Webhook integration to get a Slack/Discord ping when you hit 80% of your cap
