title: GC AI External Chat Files API
version: 1.0.0
description: 'The GC AI External API allows programmatic access to GC AI''s chat capabilities. It''s designed for integration with workflow automation tools like Zapier, Make, n8n, or custom applications.
## Authentication
All API requests must include an API key in the `Authorization` header:
```
Authorization: gcai_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```
API keys can be created in the GC AI app under **Settings → API**.
## Multi-turn Conversations
Conversations can span multiple turns: pass the `chat_id` returned by a completion back on your next request to continue the same chat. See [Multi-turn Conversations](/api-reference/concepts/multi-turn).
## Current Limitations
The following is not yet available via API:
- **Interactive clarification**: the model cannot pause to ask the caller a follow-up question; the `askUserQuestions` tool is disabled on the API surface in beta
## Usage
Usage is tracked and viewable in the GC AI app under **Settings → API → View Usage**.
## Support
For API support, contact [support@gc.ai](mailto:support@gc.ai) or reach out to your account representative.'

summary: Upload a file
description: 'Upload a file to GC AI for processing and storage. Files are uploaded as multipart form data and automatically processed (text extraction, summarization, and embedding creation).
With a user-scoped key, files default to the user''s "My Files" folder. With an org-scoped key, files default to the "Organization Files" folder and the `my-files` scope is not available.
For PDFs and Word documents, extraction runs asynchronously. Poll `GET /files/{id}` until `status` is `ready`.'
