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.
It utilizes bounded concurrency to prevent overloading and supports exponential backoff with jitter for handling transient errors.
The module also features structured JSON logging and deterministic error handling.

To use this module, run the following command:
    python -m ai_dev_tool.fastapi_stripe_webhook --stripe-secret-key <secret-key> --stripe-webhook-signing-secret <signing-secret> --concurrency <concurrency-level>

Example:
    python -m ai_dev_tool.fastapi_stripe_webhook --stripe-secret-key sk_test_123 --stripe-webhook-signing-secret whsec_test_123 --concurrency 10
