AI Dev Tool: FastAPI + Pydantic v2 Idempotent Stripe Webhook Engine

1. The Production Bottleneck

We engineered this zero-bloat Python 3.12+ / AsyncIO blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

AI Dev Tool: FastAPI + Pydantic v2 Idempotent Stripe Webhook Engine

This module implements a production-ready idempotent Stripe webhook engine using FastAPI and Pydantic v2.
The architecture is designed to handle incoming webhook requests from Stripe, validate the requests, and process them in a thread-safe manner.
Bounded concurrency is implemented using a semaphore to prevent overwhelming the system with too many concurrent requests.

To run this module, use the following CLI command:
    python -m ai_dev_tool.stripe_webhook_engine --stripe-secret-key <secret-key> --max-concurrency <max-concurrency>

Example:
    python -m ai_dev_tool.stripe_webhook_engine --stripe-secret-key sk_test_123 --max-concurrency 10
