# Fastapi Apis

## Overview
FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.8+ based on standard Python type hints.

## When to Use This Skill
Use when creating RESTful web backends, microservices, or custom AI agent action gateways.

## Quick Start (with runnable code examples)

```python
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI(title="Agent API Gateway")

class QueryPayload(BaseModel):
    prompt: str
    max_tokens: int = 100

@app.post("/query")
async def handle_query(payload: QueryPayload):
    return {"status": "ok", "echo": payload.prompt}
```

## Advanced Usage
Integrate custom exception handlers, dependency injection overrides, and background task queues.
