## What it does

The skill covers calling models from Netlify Functions and Edge Functions through each provider's official SDK. The gateway injects credentials, so you instantiate with no arguments: `new Anthropic()`, `new OpenAI()`, `new GoogleGenAI({})`, `new TypeSafeClient()`, `new OpenRouter()`. The TypeSafe example routes form submissions: a `choice(prompt, options)` question, with the answer at `answers.<question>.choice`.

Several things break easily. The gateway is not browser-callable, so calls belong in functions — client-side code has no injected credentials. Build scripts, prerender and build plugins get no credentials either and fail. A synchronous function is bound by the 60-second timeout, so stream long generations or move them to a background function. And the gateway stays inactive until the project has at least one production deploy: run `netlify deploy --prod` once even for local dev.

Model lists change, so don't hardcode them — check the live providers endpoint. Netlify never overrides a provider key you set at project or team level; the gateway defers to yours. For Gemini, injection is skipped when `GOOGLE_API_KEY` or `GOOGLE_VERTEX_BASE_URL` is set. The OpenRouter SDK needs 1.2.43 or later: earlier versions ignore `OPENROUTER_BASE_URL` and fail with a 401.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-ai-gateway -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/netlify-ai-gateway/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/netlify-ai-gateway/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-ai-gateway -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/netlify-ai-gateway/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-ai-gateway -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/netlify-ai-gateway/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install netlify/context-and-tools netlify-ai-gateway
```

2. **Manually: put the files in place**
- File: `.github/skills/netlify-ai-gateway/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-ai-gateway -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/netlify/context-and-tools --path skills/netlify-ai-gateway
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/netlify-ai-gateway/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add netlify/context-and-tools --skill netlify-ai-gateway -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/netlify/context-and-tools/tree/HEAD/skills/netlify-ai-gateway/SKILL.md

## When to use it
- add a chatbot to a Netlify app without signing up with a provider
- call OpenAI, Anthropic or Gemini from a Netlify Function
- route contact form submissions to teams with TypeSafe
- stream a long generation to stay inside the function timeout
- debug gateway calls that fail at build time or return 401

## Example prompts
- Add a Netlify function at `netlify/functions/joke.js` served at `/api/joke` that calls Anthropic through the AI Gateway
- Write a background function that streams a long model response and saves the output to Netlify Blobs
- Set up TypeSafe routing for contact form submissions with a `choice` question offering sales, support and spam

Reach for this when adding an AI feature to a Netlify app — a chatbot, text summarizer, image generator, joke/content generator, form-submission routing or analysis, or any LLM call — or when wiring the OpenAI/Anthropic/Gemini/TypeSafe/OpenRouter SDK into a Netlify Function, choosing which env vars to use, streaming long generations, or debugging why gateway calls fail at build time or return 401.

# Netlify AI Gateway

Call AI models from Netlify compute using the provider's official SDK. The gateway injects provider credentials automatically — instantiate the SDK with no args and it works.

**Use the provider SDK with injected env credentials.** Do not hand-roll a raw `fetch()` against the gateway URL, and do not wire calls to `NETLIFY_AI_GATEWAY_KEY` / `NETLIFY_AI_GATEWAY_URL` as your default path — those are for third-party/unsupported libraries only (see below).

## Footguns (read first)

- **Not browser-callable.** Gateway calls belong in Functions or Edge Functions — never in client-side code. The browser has no injected credentials.
- **Runtime-only credentials.** Never call the gateway from build scripts, prerender/SSG, or build plugins — those get no credentials and fail. Do AI work at request time; cache to Netlify Blobs if output must look precomputed.
- **60-second sync timeout.** A gateway call in a synchronous function is bound by the 60s function timeout. Stream long generations (SDK streaming + `ReadableStream`), or use a background function that persists output for the client to fetch. Never leave a slow generation unstreamed.
- **Requires one production deploy.** The gateway does not activate until a project has at least one production deploy. Even for local dev, run `netlify deploy --prod` once first.
