Billing

Features

Features are the billing units of Wind — one feature per AI capability in your app.

What are features?

A feature is a named AI endpoint in your app with its own pricing rule. Every request to /v1/chat/completions must include a feature_id that matches a feature you've created.

Examples: chat, image-gen, doc-summarize, code-review. Each feature can use a different model and pricing strategy.

Request → feature lookup

POST /v1/chat/completions

"feature_id": "chat" ← looks up "chat" feature → gets model + price

Pricing modes

per_call

Fixed price deducted per request, regardless of tokens used. Good for image generation or predictable workloads.

Example: $0.10 per request

User charge = price_cents

per_token

Charge a markup on the actual provider cost. You always earn a margin. Good for chat or variable-length tasks.

Example: 1.5× provider cost

User charge = provider_cost × multiplier

Fee breakdown

profit = user_charge − provider_cost

platform_fee = ceil(profit × 5%)

your_earnings = profit − platform_fee
