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)

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.
