Stripe Integration

Usage-based billing wired to every API call.

FastAPI AI Kit ships with Stripe usage metering hooks. Every API call records token consumption, which flows into Stripe's metered billing without any additional setup.

Setup in 4 steps

1Add STRIPE_SECRET_KEY to your .env
2Configure your metered billing product in Stripe Dashboard
3Set STRIPE_METERED_PRICE_ID in config
4Token usage automatically reported to Stripe meter API

What's included

Automatic Stripe usage metering on every metered endpoint
Per-API-key usage tracking mapped to Stripe subscriptions
Webhook handler for subscription lifecycle events
Configurable metering unit (tokens, requests, or custom)
Usage dashboard hooks for internal analytics

Code example

example.py

# Every metered endpoint auto-reports to Stripe
@router.post("/v1/chat")
@require_api_key(tier=["basic", "pro"])
async def chat(body: ChatRequest, key: APIKey = Depends(get_api_key)):
    response = await llm.chat(body.messages, track_tokens=True)
    # Automatically batches usage reports to Stripe
    await meter.record(
        customer_id=key.stripe_customer_id,
        units=response.tokens,
    )
    return {"reply": response.content}
