Show HN: GoogLLM – Google search that returns Markdown instead of HTML

As part of my bigger goal to make the web more agent-friendly, this weekend i decided to tackle google. The "AI-native" search APIs like Tavily and Exa exist, but they require setup and don't actually use Google's results.

So I built something simple - a proxy that takes Google search URLs and returns the results as clean markdown instead of HTML. You literally just change "google.com" to "googllm.com" in any search URL.

```bash

# Returns 500KB of HTML:

curl "https://google.com/search?q=AI+news"

# Returns clean markdown:

curl "https://googllm.com/search/AI+news"

```

*What it does:*

- Serves normal HTML to browsers (so humans can use it normally)

- Returns markdown to everything else (curl, fetch, LLM agents)

- Supports all Google search types: web, images, news, scholar, shopping, etc.

- No auth needed for testing (10 requests/hour free)

*Technical approach:*

- Content negotiation based on Accept headers

- Caches results to avoid hammering Google

- Simple pricing: 0.5¢ per search after free tier

I built this over a long weekend because I was tired of writing HTML parsers for every project. The whole thing is designed around a single principle: make Google search results consumable by LLMs without any complexity.

*Questions for HN:*

- Is this approach too simplistic? Should search APIs be more complex?

- How do you currently handle search in your LLM applications?

- Any concerns about the proxy approach vs. building from scratch?

The llms.txt documentation is intentionally comprehensive (2500 tokens) so any LLM can understand and use it immediately.

Would love feedback on the approach and any edge cases I might have missed.
