Profit Margins & Sane Defaults

1-Line Profit Margin Engine

By default, billing tools calculate raw wholesale provider costs. VibezCheck lets you declare your desired profit margin in one line:

model: vibezcheck('openai/gpt--mini', {
  customer: 'sarah@acme.com',
  pricing: {
    margin: 1.5,           // 👈 Automatically adds a 50% profit margin!
    minimumChargeUSD: 0.01, // 👈 Minimum charge 1 cent per question
  },
})

When this runs:

• ✓OpenAI Wholesale Cost: $0.0020
• ✓Billed to Customer: $0.0030 (via Stripe)
• ✓Net Profit: $0.0010 (50% margin)

The 6 Sane Defaults (Active by Default)

When you write vibezcheck('model'), six critical protections are active automatically:

1. 🛡️ $0.50 Safety Fuse Box: Automatically prevents runaway loops without requiring manual ceilings.

2. 🛟 In-Flight Abort Trapper: Captures and bills partial tokens even if a user closes their browser tab mid-stream.

3. 🏷️ Automatic 85% Cache Discounts: Passes real prompt caching savings through to preserve true margins.

4. 🚀 Serverless Lifecycle Protection: Automatically enqueues flushes via after() or waitUntil() so containers never freeze mid-billing.

5. 🔒 Zero Double-Billing: Generates deterministic SHA-256 idempotency keys on every network event.

6. 🟢 Free Local Vibe Mode: Works locally with zero Stripe keys without crashing.

Minimum Charge Floor

Use minimumChargeUSD to round up tiny fractions of a cent so every interaction covers your payment processing minimums:

pricing: {
  minimumChargeUSD: 0.01 // Every call is at least 1¢
}
