# ASG Inference

Access state-of-the-art AI models with per-token pricing and instant access.

## Overview

ASG Inference provides:

* **100+ models** — GPT-5.2, Claude Sonnet 4, Gemini 2.5 Pro, DeepSeek R1 and more
* **OpenAI-compatible** — Drop-in replacement
* **Per-token billing** — Pay exactly for usage
* **Automatic fallback** — Reliability across providers

## Quick Example

<CodeGroup>
  ```bash curl theme={null}
  curl -X POST https://agent.asgcompute.com/mcp \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -d '{
      "jsonrpc": "2.0",
      "id": 1,
      "method": "tools/call",
      "params": {
        "name": "inference_chat",
        "arguments": {
          "model": "openai/gpt-4o-mini",
          "messages": [
            {"role": "user", "content": "Explain quantum computing in one sentence."}
          ]
        }
      }
    }'
  ```

  ```typescript fetch theme={null}
  const response = await fetch('https://agent.asgcompute.com/mcp', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': 'Bearer YOUR_API_KEY',
      'X-Payment': paymentProof  // base64url-encoded payment proof
    },
    body: JSON.stringify({
      jsonrpc: '2.0',
      id: 1,
      method: 'tools/call',
      params: {
        name: 'inference_chat',
        arguments: {
          model: 'openai/gpt-4o-mini',
          messages: [
            { role: 'user', content: 'Explain quantum computing in one sentence.' }
          ]
        }

## Parameters

| Parameter     | Type    | Required | Description                        |
| :------------ | :------ | :------- | :--------------------------------- |
| `model`       | string  | Yes      | Model identifier (see table above) |
| `messages`    | array   | Yes      | Conversation messages              |
| `max_tokens`  | number  | No       | Max output tokens (default: 1024)  |
| `temperature` | number  | No       | Randomness (0-2, default: 1)       |

## Response

```json theme={null}
{
  "result": {
    "content": "Quantum computing uses quantum bits...",
    "usage": {
      "prompt_tokens": 12,
      "completion_tokens": 45,
      "total_tokens": 57
    },
    "_meta": {
      "receipt_id": "rcpt_abc123",
      "debited_usdc_microusd": 2400
    }
  }
}
```

## Streaming

For real-time responses, set `stream: true` in arguments. Streaming responses use Server-Sent Events.

## Pricing

See [Pricing](/billing/pricing) for current rates.

<Tip>
  **Cost Optimization:** Use lightweight models like `openai/gpt-4o-mini` for simple tasks and reserve frontier models for complex reasoning.
