Check if DeepSeek's search agent can access and read your site: run a real search and see which pages it opens.

Frequently Asked Questions
How does this check work?
It calls DeepSeek's Responses API with the web_search tool enabled. DeepSeek's search agent performs a live search and reports which pages it opened. We check whether your domain is among them. Note: this proves DeepSeek can access and read your site — it does not guarantee that the chat app will cite you in every answer.
Is my API key safe?
Yes. The key lives only in your browser and is sent directly to api.deepseek.com — our servers never see it. Clear the field or use a temporary key if you're on a shared computer.
What does 'accessible' mean exactly?
DeepSeek's search agent opened a page on your domain while answering the question. It means your site is reachable and readable by DeepSeek's crawler — a prerequisite for ever being cited. Whether the chat app cites you also depends on search-index exposure.
What if my site isn't accessed?
Common causes: the site is new, it's weak in search indexes (few backlinks, low crawl priority), or pages block crawlers. Fix llms.txt, robots.txt and sitemap, submit to GSC and Bing Webmaster Tools, then retry in a few days.
Does this test other AI engines?
Currently DeepSeek only — its API is the only one with server-hosted web search available to us. ChatGPT and Perplexity checks are planned; they require their own API keys.
