# app.nz

> The AI agent cloud. Run autonomous coding agents on your repos, route every major model through one OpenAI-compatible gateway, deploy AI apps and GPU models, and publish sites — all on a single API key.

app.nz is OpenAI- and Anthropic-API compatible. Point any OpenAI client at https://app.nz/v1 with your app.nz key and keep your code. Use the model `app/auto` to let the router pick the backend, or pin `provider/model` (e.g. `anthropic/claude`, `openai/gpt`). The same key meters usage across chat, embeddings, images, audio, search, coding agents, and GPU hosting.

## Start here

- [Build an agent on app.nz](https://app.nz/llms-full.txt): Read https://app.nz/llms-full.txt and follow it to integrate the gateway, launch a coding agent, and ship a deploy.
- [Task-specific LLM briefs](https://app.nz/api/instructions): Copy focused Markdown for agent, model-routing, or deployment work (`?task=agent|models|deploy`).
- [API reference](https://app.nz/docs): Every HTTP endpoint, with curl examples that match production.
- [Model gateway](https://app.nz/gateway): One OpenAI-compatible API over 15+ providers, with a live in-browser playground.
- [Model directory](https://app.nz/models): Every routable model — pricing, context window, and capabilities.

## Core API

- [Chat completions](https://app.nz/v1/chat/completions): OpenAI-compatible chat, streaming + tools. Model `app/auto` or `provider/model`.
- [Messages](https://app.nz/v1/messages): Anthropic-compatible messages, supports thinking.
- [List models](https://app.nz/v1/models): Routable models and aliases.
- [Embeddings](https://app.nz/v1/embeddings), [Images](https://app.nz/v1/images/generations), [Music](https://app.nz/v1/music/generations), [Audio/SFX](https://app.nz/v1/audio/generations), [Speech](https://app.nz/v1/audio/speech), [Transcriptions](https://app.nz/v1/audio/transcriptions), [Search](https://app.nz/v1/search): same key, same base URL.
- [Generated audio library](https://app.nz/music): `POST /api/audio/generate` creates music or SFX, saves it to an indexed public/own library, `GET /api/audio/search?q=` searches it, and `GET /api/audio` lists recent audio.
- [Google services](https://app.nz/api/google/services): Metered pass-through to Google APIs with the same app.nz key — `/v1/google/{geocode,places,routes,directions,distancematrix,timezone,elevation,staticmap,streetview,translate,tts,vision,youtube}/...`. Same paths/params as Google's own docs (key injected server-side); `GET /api/google/services` returns the per-unit price sheet.

## Products

- [Coding agent](https://app.nz/agent): Point an agent at a repo and a prompt; it branches, codes, tests, and opens a PR. Type /goal for outcome-driven execution.
- [Agents SDK](https://app.nz/agents-sdk): One API over OpenPaths, Devin, Cursor, and Codex Cloud — set `source` to choose who runs the task; every run normalizes into one trace.
- [Schedulers](https://app.nz/schedulers): Run coding-agent prompts (and CI-autofix sentinels) on a cron schedule.
- [Skills](https://app.nz/skills): Semantically search a library of ready-to-run agent skills.
- [AI use-case tools](https://app.nz/ai): 50+ job-specific tools (virtual staging, product photos, headshots, photo restore, art styles, logos, voiceovers, music, SFX, video) — each an `/ai/<slug>` page backed by the gateway image/audio/video endpoints.
- [Deploys](https://app.nz/deploys) & [Cogs](https://app.nz/cogs): Ship containers to managed CPU/GPU; run any Cog as a scale-to-zero GPU endpoint. The schema auto-generates the UI (inputs incl. file/model3d uploads; outputs incl. an interactive 3D viewer) — see https://app.nz/docs and docs/BUILDING_COGS.md in the repo.
- [Notebooks](https://app.nz/notebooks): Hosted marimo notebooks — free in-browser Pyodide or per-minute CPU/GPU sessions that auto-stop when idle. `GET /api/notebooks/pricing` lists machine rates (margin included).
- [Datasets](https://app.nz/datasets): Upload csv/json/jsonl/parquet/sqlite; agent traces auto-detect into a trace viewer; big SQLite/Parquet files serve via HTTP range reads.
- [Office docs](https://app.nz/write) & [sheets](https://app.nz/sheets): Create editable `doc` and `sheet` artifacts through `/api/artifacts` or MCP; import/export Markdown, DOCX, CSV, XLSX and HTML.
- [Media optimizer](https://app.nz/media-optimizer): Dynamic image resizing (`GET /api/media/image/{artifactId}?w=640&format=auto`), responsive image sets, and AV1 video ladders via `POST /api/media/optimize` or `app media optimize`.
- [Sites](https://app.nz/sites): Publish a static site instantly at <slug>.app.nz.
- [Payments](https://app.nz/docs): Accept payments in your hosted app (Stripe Connect direct charges — you stay merchant of record). `POST /api/payments/enable` onboards, `POST /api/payments/checkout` sells one-time or subscriptions, instant payouts, and earnings can pay your hosting bill.
- [Compute & SSH](https://app.nz/instances): Rent CPU (Hetzner) / GPU (RunPod) machines via `POST /api/instances`, then `app ssh <id>` straight in — your registered SSH keys are auto-injected. Per-second running cost shows in `app usage`.
- [CLI](https://app.nz/cli): `curl -fsSL https://app.nz/cli.sh | sh` — full GitHub-CLI parity plus agents, deploys, and the gateway.

## Optional

- [Pricing](https://app.nz/pricing): Usage-based credits (1 credit = $0.001); prepay, pay for what you use.
- [Status](https://app.nz/status): Health of the gateway, workers, queues, and deploys.
- [Security](https://app.nz/security): How code, agent commands, and secrets stay isolated.
