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.
Next.js App Router billing with Narev — greenfield setup (packages, Polar destination, @ai-billing/nextjs usage dashboard and top-up UI) and brownfield retrofit (wrap existing generateText/streamText routes with @ai-billing provider middleware, createNarevPriceResolver, destinations, customer tags, multi-provider factories, and test bypasses). Use for any Next.js + Vercel AI SDK + Narev billing task.
Current LLM prices. How to use the Narev API endpoints — list model pricing (GET) and calculate call cost (POST). Use when the user needs endpoint behavior, parameters, responses, or errors; real-time per-token rates; token-to-USD math for one call; or when they mention "Narev pricing", "model rates", "USD per token", "cost calculation", or "AI unit economics". For committing catalog snapshots or generator scripts, use update-llm-pricing.
Update LLM prices in the repo: Use this skill to snapshot live LLM pricing into a checked-in file so billing or cost math can run offline with deterministic rates. Use for any language or stack (TypeScript, Python, Go, JSON registries, etc.) — not only typescript. Use when the user wants pinned prices, wants to remove a runtime dependency on the Narev API, wants to refresh a committed pricing file, or mentions "snapshot pricing", "freeze prices", "pin model rates", "regenerate pricing file", "update pricing in the repo", or "sync token pricing from Narev".

| Skill | Purpose | When to use |
|---|---|---|
narev | Overview — picks the right skill or documentation path | Any Narev Cloud, pricing, billing, or SDK question; start here when unsure |
narev-lookup-llm-pricing | Pricing API reference — GET catalog, POST calculate, errors and contracts | Live rates, per-call cost math, endpoint behavior without committing a snapshot |
narev-update-llm-pricing | Pin pricing in-repo — patterns to snapshot the catalog into your codebase | Freeze rates, refresh a checked-in pricing file, offline or deterministic billing |
narev-nextjs | Next.js billing — greenfield setup (Polar, billed model, @ai-billing/nextjs UI) and brownfield retrofit (wrap existing Vercel AI SDK routes, multi-provider factories, test bypasses) | Any Next.js App Router app with Narev usage-based billing |
narev first; it recommends narev-lookup-llm-pricing or narev-update-llm-pricing when the task is pricing-specific.Example prompts:
| You say | Skill |
|---|---|
| “How does the Narev pricing API work?” | narev-lookup-llm-pricing |
| “Calculate USD for this token usage” | narev-lookup-llm-pricing |
| “Snapshot model pricing into a JSON file in my repo” | narev-update-llm-pricing |
| “Which Narev skill should I use for billing middleware?” | narev |
| “Set up a new Next.js app with Narev billing and usage dashboard” | narev-nextjs |
| “Add Narev billing to my existing Next.js chat route” | narev-nextjs |
