A single secret that turned any request into an operator was the only credential several routes accepted, and it had no caller left: the device pairing it existed for is on hold, and nothing in this tree or any client sent it. What remained was a key that bypassed authentication entirely, required to boot, and checked by nobody. Every route behind it had a better answer available: - Library and game sync move to host credentials. Both took a `userId` in the body, which meant one secret could write into anybody's library. A host now says which of its enrolled users a batch is for, and that claim is checked against the Steam sign-ins it actually holds — one box carries several people's accounts, so the pair is the unit. - Download-state reporting narrows to hosts alone, and the body that could name a different host is gone. Which host is reporting comes from its own credentials, and a body that still names one is refused rather than ignored. - Linking a Steam account is always for the caller. - Creating a game by hand is deleted; syncing already upserts the catalogue. - Reading the waitlist is deleted. Every address on it belongs to someone who has not agreed to anything, and answering it over HTTP made that list something a leaked key could drain. - The pairing-code routes are deleted with the flow they served. The domain module and its table stay, so returning to it is a route file rather than a migration. Nothing in the API now accepts a credential that stands for more than one caller: every request resolves to a specific user or a specific host, which is what lets a route say "the caller's own library" and mean it. BREAKING CHANGE: the `x-nestri-admin-token` header is no longer accepted and `ADMIN_SHARED_SECRET` is no longer read. `POST /games`, `GET /waitlist` and the `/pairing-code` routes are gone; `POST /games/sync` and `POST /library/sync` now require host credentials and take `userId` in the body; `POST /steam/link` no longer accepts `userId`; `POST /games/download-state` no longer accepts `hostId`.
apps/api
The public HTTP API for Nestri — a Hono app. One handler, run either as a Cloudflare Worker or as an ordinary HTTP server.
What it does
Exposes the JSON API consumed by frontends and other clients. Every route is a thin wrapper that
validates input, delegates to a domain function in @nestri/core,
and returns { data: ... }. All business logic lives in the core package.

Key details
- Auth:
Authorization: Bearer …, carrying either a session token verified against@nestri/author a personal access token resolved from the database; or a registered host's ownx-nestri-machine-idandx-nestri-machine-secret. There is no shared secret and no credential that stands for more than one caller, so every route resolves to a specific user or a specific host — which is what lets a route say "the caller's own library" and mean it. - Errors: centralized
VisibleError→ typed JSON responses. - Settings arrive as bindings or as environment variables, and two of them have one spelling of
each: Postgres is
HYPERDRIVEorDATABASE_URL, and the route to the issuer is anAUTHservice binding orAUTH_INTERNAL_URL. Nothing here branches on which it got. AUTH_ISSUER_URLis the issuer's public URL and never the internal one, because it is compared literally against theissclaim on every token.
Running
bun run dev # under the Workers runtime, on :3000
bun run serve # as a plain process, on $PORT (default 3000)
Needs a Postgres database and a reachable issuer. Full list and deployment steps:
