What is it?

lore.md is a minimal Cloudflare Worker that returns a single AI-generated markdown essay for each hostname, refreshed once per UTC day. The first request of the day triggers generation through Cloudflare AI Gateway using an xAI model, and the result is stored in a Durable Object and cached at the edge, so each domain costs one model call per day.

The output is plain markdown rendered inside a monospace HTML page with automatic light and dark themes. The Worker uses the Host header to tailor the text to each domain. An optional /stream path shows the first generation live on a cache miss, and concurrent requests share the same in-flight generation. If the model call fails, a deterministic fallback text is stored for that day.

Key features

  • 01Generates one markdown essay per hostname per UTC day.
  • 02Caches results at the edge and in a Durable Object to limit model calls.
  • 03Routes model requests through Cloudflare AI Gateway's OpenAI-compatible endpoint.
  • 04Offers a /stream endpoint that streams the first generation live.
  • 05Renders output in a monospace page with automatic light and dark modes.

Use cases

  • Running a daily auto-generated text page on your own domain.
  • Learning how to build a Cloudflare Worker with Durable Objects and AI Gateway.
  • Experimenting with per-domain prompts and daily caching patterns.
