17Townie is fully open-source and itself runs on Val Town. Pull requests welcome!
18
19To get Townie running in your Val Town account, click the **Remix** button and then add your ANTHROPIC_API_KEY. You can leave all the other environment variables blank.
20
21Authentication in Townie is handled via Val Town Oauth. However, we have not yet opened up our OAuth to anyone else, which currently makes it very awkward to use your own Townie. Here is a temporary workaround:
1# Usage Dashboard
2
3A dashboard for monitoring API usage and inference calls.

5## Features
20 index.ts # Main entry point and routing
21 auth.ts # Authentication logic
22 /api/
23 index.ts # API request handler
24 requests.ts # API endpoints for requests data
25 inference-calls.ts # API endpoints for inference calls
26 user-summary.ts # API endpoints for user summary data
27 /views/
28 layout.ts # Common layout template
