# Fusion API Integration Guide

When any Fusion module needs to call an external API (OpenAI, Anthropic, Google Maps, Twilio, Google/Microsoft OAuth), it MUST use the centralized `fusion.api.service` instead of managing its own keys.

The service lives at `fusion_api/models/api_service.py` and is an AbstractModel accessible via `self.env['fusion.api.service']`.

## Available Methods

### 1. `call_openai()` -- AI text generation via OpenAI

```python
result = self.env['fusion.api.service'].call_openai(
    consumer='fusion_clock_ai',       # your module's technical name
    feature='timesheet_summary',      # descriptive feature name for tracking
    messages=[
        {'role': 'system', 'content': 'You are a helpful assistant.'},
        {'role': 'user', 'content': 'Summarize this timesheet...'},
    ],
    model='gpt-4o-mini',              # optional, defaults to gpt-4o-mini
    max_tokens=1024,                  # optional, defaults to 1024
    user=self.env.user,               # optional, defaults to current user
)
# Returns: str (the text response)
```

### 2. `call_anthropic()` -- AI text generation via Claude

```python
result = self.env['fusion.api.service'].call_anthropic(
    consumer='fusion_notes',
    feature='voice_transcription',
    messages=[
        {'role': 'user', 'content': 'Transcribe this text...'},
    ],
    system='You are a medical transcription assistant.',  # optional system prompt
    model='claude-sonnet-4-20250514',                           # optional, defaults to claude-sonnet-4-20250514
    max_tokens=1024,                                      # optional
)
# Returns: str (the text response)
```

### 3. `get_api_key()` -- raw API key for non-AI services

```python
api_key = self.env['fusion.api.service'].get_api_key(
    provider_type='google_maps',      # one of: google_maps, twilio, custom
    consumer='fusion_shipping',       # your module's technical name
    feature='geocoding',              # optional feature name
)
# Returns: str (the raw API key to use in your own HTTP calls)
```

### 4. `get_oauth_credentials()` -- OAuth tokens for Google/Microsoft

```python
creds = self.env['fusion.api.service'].get_oauth_credentials(
    provider_type='google_oauth',     # google_oauth or microsoft_oauth
    consumer='fusion_schedule',
    feature='calendar_sync',
)
# Returns: dict with keys:
#   client_id, client_secret, access_token, refresh_token, token_expiry, redirect_uri
```

## Provider Types

| Type | Use For |
|------|---------|
| `openai` | GPT-4o, GPT-4o-mini, o1, etc. |
| `anthropic` | Claude Sonnet, Haiku, Opus |
| `google_maps` | Geocoding, Places, Distance Matrix |
| `google_oauth` | Google Calendar, Drive OAuth |
| `microsoft_oauth` | Microsoft Calendar, Graph OAuth |
| `twilio` | SMS, Voice |
| `custom` | Any other API provider |

## What Happens Automatically

- The calling module is auto-registered as a consumer in Fusion API
- Every call is logged with: tokens, cost, response time, user, feature, model
- Budget caps (monthly/daily) are enforced before each call
- Rate limits (RPM/RPD) are enforced before each call
- Per-user limits are checked if configured
- On limit exceeded, a `UserError` is raised with a clear message

## Phased Migration Pattern

Do NOT add `fusion_api` as a hard dependency. Use a try/fallback pattern so the module works with or without Fusion API installed:

```python
def _call_ai(self, messages, feature='general'):
    """Call OpenAI through Fusion API, falling back to own key."""
    try:
        return self.env['fusion.api.service'].call_openai(
            consumer='fusion_clock_ai',
            feature=feature,
            messages=messages,
        )
    except Exception:
        api_key = self.env['ir.config_parameter'].sudo().get_param(
            'fusion_clock_ai.openai_api_key'
        )
        if not api_key:
            raise
        from openai import OpenAI
        client = OpenAI(api_key=api_key)
        response = client.chat.completions.create(
            model='gpt-4o-mini', messages=messages,
        )
        return response.choices[0].message.content
```

## Rules

- NEVER hardcode API keys in Python code
- NEVER store API keys in `ir.config_parameter` for new modules -- use Fusion API
- ALWAYS pass the module's technical name (e.g. `fusion_clock_ai`) as the `consumer` parameter
- ALWAYS pass a descriptive `feature` string for usage tracking granularity
- NEVER catch and silently swallow errors from `fusion.api.service` -- let UserError propagate
- DO NOT add `fusion_api` to `depends` in `__manifest__.py` -- use the fallback pattern above
- The `consumer` string should match the module's technical name exactly (folder name)

## Odoo 19 Conventions

- This project targets Odoo 19 (Community/Enterprise)
- No hardcoded colors in views or SCSS -- let Odoo handle dark/light theming
- Use `res.groups.privilege` for security groups (not `category_id`)
- Do not use deprecated `ir.cron` fields (`numbercall`, `doall`)
- Settings views: use `name=` attribute on `<app>` tags, not `data-key=`
