# Developer Documentation - AITBC

Build on the AITBC platform: SDKs, APIs, bounties, and resources for developers.

## Quick Start

### Prerequisites

- Git
- Docker and Docker Compose
- Node.js 18+ (for frontend)

### Setup Development Environment

```bash
# Clone the repository
git clone https://github.com/oib/AITBC.git
cd aitbc

# Start all services
docker-compose up -d

# Check status
docker-compose ps
```

## Architecture Overview

The AITBC platform consists of:

- **Blockchain Node** (Rust) - PoA/PoS consensus layer
- **Coordinator API** (Python/FastAPI) - Job orchestration
- **Marketplace Web** (TypeScript/Vite) - User interface
- **Miner Daemons** (Go) - GPU compute providers
- **Wallet Daemon** (Go) - Secure wallet management

## Contributing

## Example: Adding a New API Endpoint

The coordinator-api uses Python with FastAPI. Here's how to add a new endpoint:

### 1. Define the Schema

```python
# File: coordinator-api/src/app/schemas.py

from pydantic import BaseModel
from typing import Optional

class NewFeatureRequest(BaseModel):
    """Request model for new feature."""
    name: str
    value: int
    options: Optional[dict] = None

class NewFeatureResponse(BaseModel):
    """Response model for new feature."""
    id: str
    status: str
    result: dict
```

### 2. Create the Router

```python
# File: coordinator-api/src/app/routers/new_feature.py

from fastapi import APIRouter, Depends, HTTPException
from ..schemas import NewFeatureRequest, NewFeatureResponse
from ..services.new_feature import NewFeatureService

router = APIRouter(prefix="/v1/features", tags=["features"])

@router.post("/", response_model=NewFeatureResponse)
async def create_feature(
    request: NewFeatureRequest,
    service: NewFeatureService = Depends()
):
    """Create a new feature."""
    try:
        result = await service.process(request)
        return NewFeatureResponse(
            id=result.id,
            status="success",
            result=result.data
        )
    except ValueError as e:
        raise HTTPException(status_code=400, detail=str(e))
```

### 3. Write Tests

```python
# File: coordinator-api/tests/test_new_feature.py

import pytest
from fastapi.testclient import TestClient
from src.app.main import app

client = TestClient(app)

def test_create_feature_success():
    """Test successful feature creation."""
    response = client.post(
        "/v1/features/",
        json={"name": "test", "value": 123}
    )
    assert response.status_code == 200
    data = response.json()
    assert data["status"] == "success"
    assert "id" in data

def test_create_feature_invalid():
    """Test validation error."""
    response = client.post(
        "/v1/features/",
        json={"name": ""}  # Missing required field
    )
    assert response.status_code == 422
```

> **💡 Pro Tip:** Run `make test` locally before pushing. The CI pipeline will also run all tests automatically on your PR.
