# omni-api-keys

This skill creates, lists, rotates and revokes Anthropic API keys, and sets per-key scopes and limits. Useful when keys are handed out from inside an agent.

## What it does

The skill covers the whole key lifecycle on Anthropic: create, list, update, regenerate, revoke. It also grants a key access to specific models and combos, and shows which devices have used that key.

Under the hood it calls a local API at `http://localhost:20128`. Listing keys goes through `GET /api/keys`, creation through `POST /api/keys`, and model access changes atomically via `POST /api/keys/{id}/access`. A separate set of endpoints handles key groups and their permissions.

Every request needs a Bearer token, obtained with `POST /api/auth/login`, or `REQUIRE_API_KEY=false` for local development. If a key allows all models or all combos, adding new ones through `/access` requires `switchToRestricted: true` — otherwise you get a 409 Conflict. Concurrent `PATCH /api/keys/{id}` calls overwrite the policy entirely outside that lock, so keep it in mind when something besides the agent edits keys.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add cheaper-inference/OmniRoute --skill omni-api-keys -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add cheaper-inference/OmniRoute --skill omni-api-keys -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add cheaper-inference/OmniRoute --skill omni-api-keys -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install cheaper-inference/OmniRoute omni-api-keys
```

2. **Manually: put the files in place**
- File: `.github/skills/omni-api-keys/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add cheaper-inference/OmniRoute --skill omni-api-keys -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/cheaper-inference/OmniRoute --path skills/omni-api-keys
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add cheaper-inference/OmniRoute --skill omni-api-keys -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/cheaper-inference/OmniRoute/tree/HEAD/skills/omni-api-keys/SKILL.md

## When to use it
- issue a key for a new service and limit it to certain models
- check which keys are currently active
- revoke a key that leaked
- regenerate a key without losing its settings
- group keys under shared permissions

## Example prompts
- List the Anthropic API keys
- Create a new key and allow it only the gpt-4o model
- Revoke the key with id `abc123`

## Overview

Create, list, rotate, and revoke OmniRoute API keys. Control per-key scopes, spending limits, and expiration. Keys gate access to all proxy and management endpoints.

## Authentication

All requests require a valid Bearer token or session cookie. Obtain a token via `POST /api/auth/login` or configure `REQUIRE_API_KEY=false` for local development.

## Endpoints

### GET /api/keys

List API keys

```bash
curl http://localhost:20128/api/keys \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
```

### POST /api/keys

Create API key

```bash
curl -X POST http://localhost:20128/api/keys \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### GET /api/keys/{id}

Get API key

```bash
curl http://localhost:20128/api/keys/{id} \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
```

### PATCH /api/keys/{id}

Update API key

```bash
curl -X PATCH http://localhost:20128/api/keys/{id} \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### DELETE /api/keys/{id}

Delete API key

```bash
curl -X DELETE http://localhost:20128/api/keys/{id} \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
```

### POST /api/keys/{id}/access

Add or remove allowed models and combos on an API key atomically

Adds or removes allowed models and combos on an API key without lost updates.
Serialized per key ID using an in-process async lock.
Keys allowing all models (modelAccessMode: all) or all combos (allowedCombos containing 'combo/*')
require switchToRestricted: true when adding new models or combos, otherwise returning a 409 Conflict.
When switching to restricted mode, the allowlist becomes exactly the net added items (at least one required).
Direct concurrent PATCH calls to /api/keys/{id} completely overwrite the policy outside this lock.


```bash
curl -X POST http://localhost:20128/api/keys/{id}/access \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'
```

### GET /api/keys/{id}/devices

List devices for an API key

Lists the distinct devices (masked IP + User-Agent fingerprints) tracked for an API key by the in-memory device tracker. IPs are masked before storage; the route never sees the raw client IP.

```bash
curl http://localhost:20128/api/keys/{id}/devices \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN"
```

### POST /api/keys/{id}/regenerate

POST keys › <id> › regenerate

```bash
curl -X POST http://localhost:20128/api/keys/{id}/regenerate \
  -H "Authorization: Bearer $OMNIROUTE_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'
```
