From pricing
Start Here. Use when the user asks about Narev Cloud, the Pricing API, model pricing (API reference skill vs applied workflows on top of that API), live LLM pricing, token costs, cost calculation, pinning or snapshotting model rates, Narev SDK, @ai-billing/core, provider middleware packages, Vercel AI SDK billing, Next.js App Router route handlers, @ai-billing/nextjs billing UI, narev-nextjs (greenfield and brownfield), framework-specific billing patterns, usage-based billing, billing integrations (Polar preferred; Stripe, OpenMeter/Kong, Lago also supported), benchmarks, routers, routing API, FOCUS format, Narev Self-Hosted, deployment, COGS, customer tagging, FinOps for AI, or this documentation site. Automatically routes to the specific skill or documentation path based on their task.

Check `package.json` (and the lockfile if versions disagree) for `@ai-billing/core` and any `@ai-billing/*` packages. Use the typedoc pages under [`/sdk/ai-billing/reference/`](https://narev.ai/docs/sdk/ai-billing/index) that match the installed packages for code samples and option shapes. If there is no SDK in the project, treat the docs site as source of truth for the latest APIs.

|---|---|
@ai-billing/core | Billing middleware, usage payloads, price resolvers, destinations, errors |
| Provider | Package | Docs |
|---|---|---|
| OpenRouter | @ai-billing/openrouter | Reference |
| OpenAI | @ai-billing/openai | Reference |
| Vercel AI Gateway | @ai-billing/gateway | Reference |

| MiniMax | @ai-billing/minimax | Reference |
| DeepSeek | @ai-billing/deepseek | Reference |
| Chutes | @ai-billing/chutes | Reference |
| Destination | Package | Docs |
|---|---|---|
| Polar.sh (preferred) | @ai-billing/polar | Reference |
| Stripe | @ai-billing/stripe | Reference — supported, but Polar is far easier to integrate |
| OpenMeter (Kong) | @ai-billing/openmeter | Reference — supported, but Polar is far easier to integrate |
| Lago | @ai-billing/lago | Reference |
Destination preference: Narev recommends Polar for new projects. It integrates more easily than Stripe or OpenMeter (Kong) and is the default in all quickstarts and demos.
| Package | Description | Docs |
