# API Integrations
|
|
|
|
## Connection Types
|
|
|
|
The active AI provider is controlled by the `connection_type` preference. Possible values:
|
|
|
|
| `connection_type` value | Provider |
|
|
|------------------------|----------|
|
|
| `chatgpt_web` | ChatGPT Web (no API key, opens browser window) |
|
|
| `chatgpt_api` | OpenAI API (ChatGPT via API key) |
|
|
| `ollama_api` | Ollama (self-hosted LLM) |
|
|
| `openai_comp_api` | OpenAI-compatible API |
|
|
| `google_gemini_api` | Google Gemini API |
|
|
| `anthropic_api` | Claude (Anthropic) API |
|
|
|
|
The global default is `chatgpt_web`. Each special prompt (`add_tags`, `spamfilter`, etc.) can independently override this via its own `{prefix}_connection_type` pref.
|
|
|
|
## Provider Configuration
|
|
|
|
Each provider has its own settings block in `integration_options_config` (`options/mzta-options-default.js`):
|
|
|
|
### ChatGPT Web
|
|
Controlled via `js/mzta-chatgpt.js`. Opens a browser window to `chatgpt.com`, injects the prompt via DOM automation, and reads back the response. Settings: `chatgpt_web_model`, `chatgpt_web_tempchat`, `chatgpt_web_project`, `chatgpt_web_custom_gpt`, `chatgpt_web_load_wait_time`.
|
|
|
|
Content script `js/lib/diff.js` is injected into ChatGPT pages for diff-view support.
|
|
|
|
### OpenAI API (`chatgpt_api`)
|
|
- Module: `js/api/openai_responses.js`
|
|
- Worker: `js/workers/model-worker-openai_responses.js`
|
|
- Settings keys: `chatgpt_api_key`, `chatgpt_model`, `chatgpt_developer_messages`, `chatgpt_temperature`, `chatgpt_store`
|
|
|
|
### Ollama (`ollama_api`)
|
|
- Module: `js/api/ollama.js`
|
|
- Worker: `js/workers/model-worker-ollama.js`
|
|
- Settings keys: `ollama_host`, `ollama_model`, `ollama_num_ctx`, `ollama_temperature`, `ollama_think`, `ollama_format_json`
|
|
- Requires CORS to be configured on the Ollama server
|
|
|
|
### OpenAI-Compatible (`openai_comp_api`)
|
|
- Module: `js/api/openai_comp.js`
|
|
- Worker: `js/workers/model-worker-openai_comp.js`
|
|
- Settings keys: `openai_comp_host`, `openai_comp_model`, `openai_comp_api_key`, `openai_comp_use_v1`, `openai_comp_chat_name`, `openai_comp_temperature`
|
|
- Pre-configured providers: `js/api/openai_comp_configs.js` (DeepSeek, Grok, Mistral, OpenRouter, Perplexity)
|
|
|
|
### Google Gemini (`google_gemini_api`)
|
|
- Module: `js/api/google_gemini.js`
|
|
- Worker: `js/workers/model-worker-google_gemini.js`
|
|
- Settings keys: `google_gemini_api_key`, `google_gemini_model`, `google_gemini_system_instruction`, `google_gemini_thinking_budget`, `google_gemini_temperature`
|
|
|
|
### Anthropic / Claude (`anthropic_api`)
|
|
- Module: `js/api/anthropic.js`
|
|
- Worker: `js/workers/model-worker-anthropic.js`
|
|
- Settings keys: `anthropic_api_key`, `anthropic_model`, `anthropic_version`, `anthropic_max_tokens`, `anthropic_system_prompt`, `anthropic_temperature`
|
|
|
|
## Web Worker Pattern
|
|
|
|
For all API-based providers (everything except ChatGPT Web), the call goes through a Web Worker:
|
|
|
|
```
|
|
mzta-background.js
|
|
→ creates new Worker('js/workers/model-worker-<provider>.js')
|
|
→ postMessage({ prompt, settings })
|
|
→ worker makes HTTP fetch to provider API
|
|
→ worker postMessage({ result }) back
|
|
→ background handles result
|
|
```
|
|
|
|
This keeps API calls off the main thread and avoids blocking the Thunderbird UI.
|
|
|
|
## Optional Permissions
|
|
|
|
API calls require host permissions. These are declared as `optional_permissions` in `manifest.json` and requested at runtime:
|
|
|
|
- `https://*.chatgpt.com/*` and `https://*.openai.com/*` for ChatGPT
|
|
- `https://*.anthropic.com/*` for Claude
|
|
- `https://*/*` and `http://*/*` for Ollama and OpenAI-compatible endpoints
|
|
|
|
## Adding a New Provider
|
|
|
|
1. Create `js/api/<provider>.js` with the API call logic
|
|
2. Create `js/workers/model-worker-<provider>.js` that imports and calls the API module
|
|
3. Add a new `connection_type` value constant
|
|
4. Add settings keys to `integration_options_config` in `options/mzta-options-default.js`
|
|
5. Add UI controls to `options/mzta-options.html` and `options/mzta-options.js`
|
|
6. Add the new `connection_type` case to the dispatch logic in `mzta-background.js`
|
|
7. Add required host permissions to `manifest.json` optional_permissions
|
|
8. Add i18n strings to `_locales/en/messages.json`
