Share of AI Traffic

Market share among AI assistants and LLM crawlers hit over the last 30 days (5,616 total requests).

Who's reading the API

125,354 requests from 150 countries in the last 30 days.

Every request to our search, listing, and llms.txt endpoints gets classified server-side from its User-Agent. “AI assistants” only counts named systems. Generic crawlers and unclassified agents are counted separately, so the two numbers never get blended into one.

Why we're open about this

No login gate, no filtering. This is the same dashboard our team looks at.

Crawlers are allowlisted

Our robots.txt allows GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Amazonbot, and Bytespider to read the catalog, search API, and llms-full.txt.

Built to be cited

We set ai-input=yes so answer engines and assistants can quote us directly.

Not used for training

We set ai-train=no. The catalog is available to read, not to train on.
