How we crawl the web for AI search
We named Linkup's crawler after Gerardus Mercator, the 16th-century Flemish cartographer behind the 1569 map projection that let sailors plot a course across the globe as a straight line. His name became shorthand for mapping the world, so it went to the component that turns the open web into something you can navigate.

Why LLM web search returns inaccurate answers, and how to fix grounding at the API layer
LLM websearch is inaccurate because the retrieval layer feeds stale, low-precision, uncited context - fix it at the API, not the prompt.

What is Zero Data Retention and why does it matter for AI teams?
Zero Data Retention means your queries and results are never stored once a request completes. Delivering that guarantee is less a matter of policy than of infrastructure: a provider can only promise that nothing is retained if it controls every system the query touches.

Your search API isn't what's expensive. Your tokens are.
When teams evaluate retrieval APIs at scale, the first question is almost always price per call. It's the wrong question - and it leads to the wrong architecture. The finding, up front: the cost of web search in a production AI system isn't the API call. It's what the results do to your token bill downstream. A retrieval layer that looks cheap per call but forces extra fetches, re-searches, and bloated context is the expensive option. The right unit of comparison is cost per resolved query.

Your AI searched the web. It just didn't read it.
Your AI searched the web. It just didn't read it. A native web search answer can cite sources, link URLs, and still contain facts that appear nowhere in those sources. The answer looks grounded - there's no way to tell from the output that it isn't. That's the failure mode this post documents: not a worse answer, an unverifiable one. This is a writeup of a live demo comparison between Claude's native web search and Linkup's retrieval API - what we tested, what we found, and why it matters for anyone building production AI systems on top of web search.

Why developers are choosing Linkup over Exa
If you are comparing Linkup vs Exa for an AI application, the short answer is: Linkup wins on factual accuracy, predictable pricing, and GDPR compliance. Exa wins on semantic discovery and entity enrichment. For most production RAG pipelines and AI agents, Linkup is the stronger choice. Both APIs are purpose-built for AI developers and operate proprietary web indices. The right choice depends on what your application does with retrieved content and what your cost model looks like at scale.

Linkup vs Parallel: which web search API holds up in production?
Most web search APIs work fine in a demo. The question is what happens when something goes wrong in production, when a regulator asks where your AI's answer came from, when your search bill doubles because query complexity spiked, or when your infrastructure team flags that data is leaving your region. That is where Linkup and Parallel diverge.
