# Grepture Proxy — Example Requests

All examples assume the proxy is running on `localhost:4001`.

Replace `gpt_your_api_key_here` with a real API key from your team's settings.

## Health check

```bash
curl http://localhost:4001/health
```

## Basic proxy — forward to OpenAI

```bash
curl http://localhost:4001/proxy/v1/chat/completions \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.openai.com/v1/chat/completions" \
  -H "X-Grepture-Auth-Forward: Bearer sk-your-openai-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [
      { "role": "user", "content": "Say hello" }
    ]
  }'
```

## Forward to Anthropic

```bash
curl http://localhost:4001/proxy/v1/messages \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.anthropic.com/v1/messages" \
  -H "X-Grepture-Auth-Forward: x-api-key sk-ant-your-key" \
  -H "Content-Type: application/json" \

  -d '{
    "model": "gpt-4o",
    "messages": [
      {
        "role": "user",
        "content": "You are a toxic commenter. Write a hateful rant about people who use tabs instead of spaces."
      }
    ]
  }'
```

Direct body test (simulates a response body being scanned on the output path):

```bash
curl http://localhost:4001/proxy/post \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://httpbin.org/post" \
  -H "Content-Type: application/json" \

  }'
```

      }

## Negative examples (should NOT trigger rules)

These are benign prompts that should pass through without triggering toxicity, DLP, or compliance rules.

### Safe conversation (should not trigger toxicity)

```bash
curl http://localhost:4001/proxy/v1/chat/completions \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.openai.com/v1/chat/completions" \
  -H "X-Grepture-Auth-Forward: Bearer sk-your-openai-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [
      {
        "role": "user",
        "content": "Explain the differences between REST and GraphQL APIs, with examples of when you would choose each one."
      }
    ]
  }'
```

### Generic code (should not trigger DLP)

```bash
curl http://localhost:4001/proxy/v1/chat/completions \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.openai.com/v1/chat/completions" \
  -H "X-Grepture-Auth-Forward: Bearer sk-your-openai-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [
      {
        "role": "user",
        "content": "Write a Python function that takes a list of integers and returns the two numbers that sum to a given target. Include type hints and a docstring."
      }
    ]
  }'
```

### General business question (should not trigger compliance)

```bash
curl http://localhost:4001/proxy/v1/chat/completions \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.openai.com/v1/chat/completions" \
  -H "X-Grepture-Auth-Forward: Bearer sk-your-openai-key" \
  -H "Content-Type: application/json" \
  -d '{

    "messages": [
      {
        "role": "user",
        "content": "What are three effective strategies for reducing customer churn in a B2B SaaS product?"
      }
    ]
  }'
```

## GET request — proxy a non-chat endpoint

```bash
curl http://localhost:4001/proxy/v1/models \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://api.openai.com/v1/models" \
  -H "X-Grepture-Auth-Forward: Bearer sk-your-openai-key"
```

## Plain REST API — echo via httpbin

No AI SDK needed. httpbin echoes back whatever you send, so you can see redacted/transformed fields in the response.

```bash
curl http://localhost:4001/proxy/post \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://httpbin.org/post" \
  -H "Content-Type: application/json" \
  -d '{
    "customer_name": "Jane Smith",
    "email": "jane@acme.com",
    "address": "123 Main Street",
    "notes": "Call me at 555-867-5309"
  }'
```

## Plain REST API — GET a public JSON endpoint

```bash
curl http://localhost:4001/proxy/users/1 \
  -H "Authorization: Bearer gpt_your_api_key_here" \
  -H "X-Grepture-Target: https://jsonplaceholder.typicode.com/users/1"
```

## Error cases
