| # Prompt API for extension |
| |
| This document describes the status of the current implementation of the |
| [**Prompt API**](https://github.com/webmachinelearning/prompt-api) for Chrome |
| extensions, and how to verify. |
| |
| ## What’s supported |
| |
| The implementation generally intends to follow the |
| [explainer](https://github.com/explainers-by-googlers/prompt-api). |
| |
| ## Activation |
| |
| The API can be enabled by participating in the |
| [extension origin trial](https://developer.chrome.com/blog/prompt-api-origin-trial) |
| named `AIPromptAPIForExtension`. After obtaining the trial token, the |
| extension authors need to configure it in the `manifest.json`: |
| |
| ```json |
| { |
| "trial_tokens": [<GENERATED_TOKEN>], |
| } |
| ``` |
| |
| ## Verifying the API is working |
| |
| The extension authors can verify if the API is available by checking for the |
| presence of the `LanguageModel` entrypoint from extension window and worker |
| scripts. If the object is defined, the authors can follow the |
| [explainer](https://github.com/explainers-by-googlers/prompt-api) and |
| [developer docs](https://developer.chrome.com/docs/extensions/ai/prompt-api) |
| to check availability and test the APIs usage. |
