Overview

Linkup is a developer-focused API that connects AI applications to fresh, accurate information from across the web. Instead of relying solely on a model's static training data, apps can query Linkup to retrieve grounded facts, citations, and up-to-date context in real time. The service is aimed at teams building chatbots, agents, and research tools that need reliable answers backed by verifiable sources. It handles the search, retrieval, and structuring of web content so developers can focus on their product logic rather than scraping and ranking pipelines.

Use it every day

Honestly didn't expect to like it this much. Developer documentation and SDKs is exactly what I needed, and simple API integration for developers. I do wish quality depends on available web sources, but I reach for it almost every day now and it just clicks.

Does the job

Pretty happy overall. Compatible with agent and RAG frameworks just works and reduces hallucinations with sourced web data. Usage-based pricing can scale with traffic can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Marcus Bell

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on source citations for verifiability, and simple API integration for developers caught me off guard. still, I'd recommend giving it a real trial.

Compared a few options

Evaluated this against two competitors. Where it wins: developer documentation and SDKs and simple API integration for developers. Where it lags: usage-based pricing can scale with traffic. On balance the feature set — especially structured responses ready for LLMs — justifies the 4 stars for our use case.
