The key is auto-minted on first use, viewable and rotatable\n on the **Data** tab. There is no per-customer scoping (that's what uAgents is for) — one key,\n checked in constant time, guards every fn.\n- **Admin UI** (`/`) — **Val Town sign-in**, gated to an allow-list, same pattern as uAgents. Set\n the `ADMIN_USERS` env var (Val Town sidebar) to a comma-separated list of Val Town usernames\n (case-insensitive). Sign-in uses\n [`std/oauth`](https://docs.val.town/guides/auth/#sign-in-with-val-town); see `backend/auth.ts`.\n\n## Admin UI\n\nA single page at `/` with five hash-routed tabs (`/#data`, `/#debug`, `/#integration`, `/#activity`,\n`/#info`):\n\n| Tab | What |\n| --------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| **Data** | Mock user fields (returned by `/get-user-details`) + the global API key |\n| **Debug** | Pick a fn, edit its JSON body, and fire a live call from the browser — see the resolved URL, `Authorization` header, and an equivalent `curl` update live |\n| **Integration** | Pick a fn and get its endpoint URL, auth header, description, and parameters JSON Schema — ready to paste into a ToughTongue AI tool/function definition |\n| **Activity** | Fn catalog + a live request/webhook log |\n| **Info** | Role, auth model, quick start, pairing with uAgents |\n\n## Fn endpoints\n\nAll POST-only, all require the API key:\n\n| Path | Purpose |\n| ----------------------- | --------------------------------------------------------------------------------------- |\n| `/get-user-details` | Returns the mock user from SQLite |\n| `/get-information` | Weather + headlines, padded to ~3s |\n| `/get-information-slow` | Weather + headlines, padded to ~20s |\n| `/webhook` | Captures a POST body for the Activity log — a regular fn like the rest, not a catch-all |\n\n`/get-information*` accept an optional JSON body `{\"location\": \"Tokyo\"}`; without one they fall back\nto the mock user's `location` (Data tab, default `Paris`).\n\nReady-to-run `curl` examples with the real deployed base URL filled in live on the **Activity** tab\n(empty-state) and the **Info** tab (quick start) — no guessing your val's hostname.\n\n### Weather + headlines API options\n\nBoth fns call **free, keyless** public APIs — no signup, no rate-limit surprises for a dev tool:\n\n- **Weather — [Open-Meteo](https://open-meteo.com)** (chosen). Free forecast + geocoding APIs, no\n API key, no rate limit for reasonable use. Alternatives considered: [wttr.in](https://wttr.in)\n (free, keyless, but plain-text/ANSI-first — JSON is an afterthought) and\n [OpenWeatherMap](https://openweathermap.org/api) (richer data, but requires a free-tier API key —\n adds a required env var for a mock endpoint).\n- **Headlines — [Hacker News (Firebase) API](https://github.com/HackerNews/API)** (chosen). Free,\n keyless, and consistently fast (`topstories.json` + a parallel `item/.json` fetch per story —\n measured ~0.3s per call). Headlines skew tech/HN, not general news. Alternatives considered:\n [GDELT DOC 2.0](https://blog.gdeltproject.org/gdelt-doc-2-0-api-debuts/) (free, keyless, broader\n real-world news coverage via full-text search — but measured ~13s per query from this repo's dev\n network, too slow/unpredictable for a 6–20s budget); **NewsAPI.org** / **GNews** / **currentsapi**\n (broader coverage and categories, but all require a free-tier API key).\n\n## File layout\n\n```\nbackend/\n api.ts HttpError, readJson/readText, dispatch (named api.ts, not\n http.ts — Val Town infers a val's type from its filename;\n only index.http.ts should be an HTTP val)\n auth.ts OAuth admin gate + global API key check\n config.ts mock-user fields, FN_SPECS (fn catalog + Debug samples)\n db.ts SQLite: settings, request log, webhook log\n settings-store.ts mock-user settings + the global API key\n information.ts weather + headlines fetch/pad logic\n fns/ one file per fn handler\n pages/ view-model assembly for SSR (admin.ts, activity.ts)\nfrontend/\n layout.tsx Shell, Tab, Panel, Picker, ReadOnlyField, UserBadge\n admin.tsx composes Data/Debug/Activity/Info into the tabbed page\n data.tsx, debug.tsx, activity.tsx, info.tsx one tab each\n auth.tsx signed-out / access-denied pages\n styles/ modular CSS layers (Next.js-style)\n tokens.ts design tokens + semantic M3 aliases (palette is runtime-generated)\n base.ts document layout + typography scale\n components.ts cards, tabs, key row, fields/buttons/tables, debug box\n index.ts composes layers → GLOBAL_CSS\n```\n\n## Push\n\nFrom this directory:\n\n```bash\nvt create uFns . --org-name ttai --upload-if-exists --no-editor-files\nvt push # ship changes\n```\n\n`val.yml` is not read by `vt` yet — it documents the val contract for a future repo wrapper over\nvt-cli.\n\n## Add a function\n\n1.

Register it in `ROUTES` inside `index.http.ts`, wrapped in `withAuth(...)` so it requires the\n global API key (dispatch wraps error handling).\n3.
