# 🚀 Free Coding API

**OpenAI & Anthropic Compatible API for Coding Tasks**

Built with skills, not money! This is a free, open-source API endpoint that runs on HuggingFace Spaces, providing coding assistance similar to OpenAI Codex and Claude Code.

## Features

- ✅ **OpenAI API Compatible** (`/v1/chat/completions`)
- ✅ **Anthropic API Compatible** (`/v1/messages`)
- ✅ **Streaming Support** (SSE)
- ✅ **Coding Optimized** (Qwen2.5-Coder model)
- ✅ **100% Free** (Runs on HF Spaces free tier)

## Quick Start

### Using OpenAI SDK

```python
from openai import OpenAI

client = OpenAI(
    base_url="https://YOUR-SPACE.hf.space/v1",
    api_key="sk-free-coding-api"
)

response = client.chat.completions.create(
    model="gpt-4",  # Mapped to Qwen2.5-Coder
    messages=[
        {"role": "system", "content": "You are an expert Python developer."},
        {"role": "user", "content": "Write a function to find prime numbers"}
    ],
    stream=True
)

for chunk in response:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
```

### Using Anthropic SDK

```python
import anthropic

client = anthropic.Anthropic(
    base_url="https://YOUR-SPACE.hf.space",
    api_key="sk-free-coding-api"
)

response = client.messages.create(
    model="claude-3-sonnet",  # Mapped to Qwen2.5-Coder
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Write a REST API in FastAPI"}
    ]
)

print(response.content[0].text)
```

### Using cURL

```bash
# OpenAI format
curl -X POST https://YOUR-SPACE.hf.space/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-free-coding-api" \
  -d '{
    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Hello, write Python code"}]
  }'

# Anthropic format
curl -X POST https://YOUR-SPACE.hf.space/v1/messages \
  -H "Content-Type: application/json" \
  -H "x-api-key: sk-free-coding-api" \
  -d '{
    "model": "claude-3-sonnet",
    "max_tokens": 1024,
    "messages": [{"role": "user", "content": "Hello, write Python code"}]
  }'
```
