# Neonous Skill

You can operate the **Neonous AI agent platform** on behalf of the user. Neonous lets users create, configure, and deploy AI agents through a web interface — with tools, MCP servers, workflows, templates, and more.

## When to Use API vs Web Interface

**Prefer suggesting the web interface** for complex or visual tasks:
- Creating/editing agents with detailed instructions → **Web UI** has a rich editor, AI-assisted instruction enhancement, and template gallery
- Building workflows → **Web UI** has a visual canvas editor (drag & drop)
- Browsing MCP catalog → **Web UI** has a searchable catalog with one-click install
- Managing MCP server environment variables → **Web UI** handles secrets securely
- Browsing community templates → **Web UI** has categories, previews, and one-click clone

**Use the API** for quick operations:
- Listing agents, tools, workflows (quick status checks)
- Chatting with an agent
- Executing a workflow
- Checking token balance
- Simple agent creation with known parameters
- Scripting and automation

The web interface is at `$NEONOUS_URL` — guide the user there for anything visual or complex.

## Authentication

All API requests require the user's API key:

```
-H "x-api-key: $NEONOUS_API_KEY"
```

Base URL: `$NEONOUS_URL` (e.g., `https://app.neonous-ai.com`).

### How to Get an API Key

Users generate API keys from the **Settings** page in Neonous. The key starts with `nn_` and is only shown once. If not set up yet:

1. Log in to Neonous at `$NEONOUS_URL`
2. Go to **Settings** > **API Keys**
3. Click **Create API Key**, give it a name
4. Copy the key (won't be shown again) and set it as `NEONOUS_API_KEY`

## Agents

### List Agents

```bash
curl -s "$NEONOUS_URL/custom/builder/agents" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq '.[]| {id, name, model, enabled}'
```

### Get Agent Details

```bash
curl -s "$NEONOUS_URL/custom/builder/agents/<AGENT_ID>" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

Returns full config including `instructions`, `predefined_tools`, `custom_tools`, `mcp_servers`.

### List Available Models

Always fetch models before creating an agent — do not hardcode model IDs:

```bash
curl -s "$NEONOUS_URL/custom/builder/agents/available-models" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq '.models[]| {id, provider, display_name, is_default}'
```

Use the model marked `is_default: true` unless the user requests a specific one.

### List Available Tools

```bash
curl -s "$NEONOUS_URL/custom/builder/agents/available-tools" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq '.tools[]| {id, name, description}'
```

Returns pre-defined tools that can be assigned to agents via `predefined_tools`.

### Create an Agent

For complex agents, recommend the web UI — it has AI-assisted generation and a template gallery. For simple agents via API:

```bash
curl -s -X POST "$NEONOUS_URL/custom/builder/agents" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My Agent",
    "description": "A helpful assistant",
    "instructions": "You are a helpful assistant that...",
    "model": "<MODEL_ID from available-models>",
    "enabled": true,
    "predefined_tools": [],
    "custom_tools": [],
    "mcp_servers": []
  }' | jq .
```

### AI-Generate Agent Config

Let Neonous AI generate a full agent config from a name and description:

```bash
curl -s -X POST "$NEONOUS_URL/custom/builder/agents/generate" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Code Reviewer",
    "description": "Reviews pull requests and suggests improvements"
  }' | jq .
```

Returns a complete agent config (name, instructions, model, tools) ready to use with the create endpoint.

### AI-Enhance Instructions

Improve existing agent instructions with AI:

```bash
curl -s -X POST "$NEONOUS_URL/custom/builder/enhance-instructions" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"instructions": "You help with code"}' | jq '.enhanced'
```

### Update an Agent

```bash
curl -s -X PUT "$NEONOUS_URL/custom/builder/agents/<AGENT_ID>" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Updated Name",
    "instructions": "Updated instructions..."
  }' | jq .
```

Only include fields you want to change.

### Delete an Agent

```bash
curl -s -X DELETE "$NEONOUS_URL/custom/builder/agents/<AGENT_ID>" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

## Chat

### Chat with an Agent

Non-streaming generate endpoint — returns a complete JSON response:

```bash
curl -s -X POST "$NEONOUS_URL/custom/builder/chat/generate" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "x-agent-id: <AGENT_ID>" \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "Hello, what can you do?"}]}' | jq .
```

Response:
```json
{
  "response": "Hi! I can help you with...",
  "usage": { "inputTokens": 42, "outputTokens": 18, "totalTokens": 60 }
}
```

For multi-turn conversations, include the full message history:
```bash
curl -s -X POST "$NEONOUS_URL/custom/builder/chat/generate" \
  -H "x-api-key: $NEONOUS_API_KEY" \
  -H "x-agent-id: <AGENT_ID>" \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [
      {"role": "user", "content": "What is 2+2?"},
      {"role": "assistant", "content": "4"},
      {"role": "user", "content": "Multiply that by 10"}
    ]
  }' | jq .
```

### List Chat Sessions

```bash
curl -s "$NEONOUS_URL/custom/builder/chat/sessions" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq '.sessions[]| {id, title, agentId, created_at}'
```

Filter by agent: append `?agentId=<AGENT_ID>`.

### Get Chat Session (with Messages)

```bash
curl -s "$NEONOUS_URL/custom/builder/chat/sessions/<SESSION_ID>" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

### Create a Chat Session

## Artifacts & Spaces

Agents generate **artifacts** during chat — code files, documents, charts, diagrams, and more. These are automatically saved and versioned. Users organize artifacts into **spaces** (project-based collections). For full artifact management, recommend the **web UI** — it has a file-manager interface with drag-and-drop, folders, and visual previews.

### Browse Artifacts

---

## Account & Tokens

### Get Token Balance

```bash
curl -s "$NEONOUS_URL/tokens/balance" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

### Token Usage History

```bash
curl -s "$NEONOUS_URL/tokens/usage" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

### Monthly Usage Summary

```bash
curl -s "$NEONOUS_URL/tokens/summary" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

### Billing, Plans & Subscriptions

Subscribing, upgrading plans, and purchasing tokens all go through Stripe checkout in the browser. **Always direct users to the web UI** at `$NEONOUS_URL/settings` (or the billing/pricing page) to subscribe or buy tokens — these cannot be completed via API alone.

You can check the user's current plan and billing status via API:

```bash
# Get available plans (shows what they can subscribe to)
curl -s "$NEONOUS_URL/custom/builder/billing/plans" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .

# Get current subscription (shows active plan)
curl -s "$NEONOUS_URL/custom/builder/billing/subscription" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .

# Get billing status
curl -s "$NEONOUS_URL/custom/builder/billing/status" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .

# Get token pricing (for purchasing extra tokens)
curl -s "$NEONOUS_URL/custom/builder/billing/token-pricing" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .

# Get purchase history
curl -s "$NEONOUS_URL/custom/builder/billing/purchases" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .

# Get invoices
curl -s "$NEONOUS_URL/custom/builder/billing/invoices" \
  -H "x-api-key: $NEONOUS_API_KEY" | jq .
```

If the user wants to subscribe, upgrade, or buy tokens, tell them to visit the **Settings > Billing** page in the web UI.

### Health Check

```bash
curl -s "$NEONOUS_URL/custom/builder/health" | jq .
```

No authentication required.

## Guidelines

- **Always list agents first** before chatting, so you know valid agent IDs.
- **Fetch models before creating** — never hardcode model IDs; use `available-models` endpoint.
- **Recommend the web UI** for complex tasks: building workflows (canvas editor), browsing templates/MCP catalog, editing agent instructions (AI-enhanced editor), and managing secrets/env vars.
- **Use the API** for quick tasks: listing resources, chatting, executing workflows, checking balance.
- For multi-turn chat, keep the full message history and pass it in each request.
- Check token balance if you get a **402** error — the user is out of tokens.
- Show the agent's response text directly to the user; omit usage details unless asked.
- Format lists as clean tables or bullet points for readability.
