# Pricing and usage

nhanaz.io.vn is a personal archive, not a paid SaaS product.

## Free tier

The public archive and its read-only endpoints are available on a free tier with no account or subscription.

It is self-serve by design. A deterministic [sandbox](https://nhanaz.io.vn/sandbox) is available for testing without touching production data.

- Public pages, Markdown resources, JSON-LD, the OpenAPI document, and the page-view counter are free to read.
- No account, subscription, checkout, paid API tier, or commercial support plan is offered.
- `GET /api/views?path=/public/path` is a small public counter endpoint. It accepts no credentials and has no paid tier.
- The hosted site is operated as a static archive with a free Vercel deployment and a free Upstash Redis counter plan. These hosting choices are implementation details, not products sold to readers.

The same facts are available as [pricing.json](https://nhanaz.io.vn/pricing.json). For the actual public surface, use [developers.md](https://nhanaz.io.vn/developers.md) and [openapi.json](https://nhanaz.io.vn/openapi.json).
