augint-billing-lib 1.8.0

Billing service library for API usage tracking and Stripe integration.

augint-billing-lib (full library bundle)

One package (augint_billing_lib) + one CLI (augint). All runtime logic lives here; IaC should be thin shims.

What it contains

• Core: BillingService with Stripe/DynamoDB/API Gateway usage orchestration
• Adapters: Stripe, DynamoDB repo, API Gateway usage, API Gateway plan admin
• Bootstrap: env + Secrets Manager wiring, CFN output discovery, plan move dispatcher
• CLI: augint with env-dump, handle-event, sync-usage, promote, demote, and optional deploy/delete helpers

Env (uses your names; no new required keys)

Required: STACK_NAME, AWS_REGION, STRIPE_SECRET_KEY
Optional: API_USAGE_PRODUCT_ID, STRIPE_SECRET_ARN, TABLE_NAME, FREE_USAGE_PLAN_ID, METERED_USAGE_PLAN_ID

Typical local flows

# 0) Install deps in your Poetry project: click, python-dotenv, boto3, stripe
# 1) Show env the CLI sees
poetry run augint env-dump

# 2) Simulate a Stripe event (and move keys between FREE_10K/METERED inside AWS)
poetry run augint handle-event --file ./fixtures/setup_intent.succeeded.json

# 3) Report last hour usage to Stripe (test mode)
poetry run augint sync-usage

# 4) Promote/demote a key (Stripe side)
poetry run augint promote --api-key ABC123
poetry run augint demote --api-key ABC123

Deploy helpers (optional)

poetry run augint deploy --infra ../augint-billing-infra --params template-params.sample.json
poetry run augint delete

Wire the CLI

Add to your pyproject.toml:

[project.scripts]
augint = "augint_billing_lib.cli:cli"

Install: poetry install
