Linkup

SF builders 📢 On the side of HumanX next week, we’re hosting a demo night with our friends at Chroma and Nozomio: live demos + raw technical creativity with some of the most cracked teams in the ecosystem. Come build anything using our stack and ship a demo. More details in the comments 

We’ll be in SF next week for HumanX! Come say hi to the Linkup team at Booth E9 on Tuesday (April 7th). We have some surprises waiting... and you'll also have the chance to meet our CEO Phil Mizrahi We’ve also got some exciting events planned in the area throughout the week 👀

Cédric Morent joins Linkup as our first DevOps Engineer. Our usage is growing 2x+ month over month. We serve AI agents across every continent. And until now, we've been scaling infra with a team of zero dedicated to it. Cédric brings 10 years of backend and infrastructure experience, exactly the type of people we need to build the Google Search of AIs. Welcome, Cédric!

What if AI could actually move the needle on how we stay healthy? On April 11, we’re bringing together top builders for a focused hackathon: 12 hours to build AI products tackling real health problems, from preventive care to mental health to chronic conditions. ⏳ Apply before this Thursday (April, 2).

March was an extraordinary month at Linkup. We’re seeing a real inflection in usage and because we’re a transversal infrastructure, the signal comes from multiple layers at once: - Legacy software companies. They’ve moved past the transformation talk and are now actually deploying AI features that get used. Providers like us are in the loop, powering the search layer behind these capabilities. - AI-native companies like Cargo 🧱, Legora, Artisan have highly-compounding adoption. As these products scale their customer base, demand on underlying infrastructure follows. It’s exciting to support this new generation of players. - Banks & hedge funds. Gradually moving from pilot to production. What’s striking is how strong some results are. Sometimes they even look too good to be true. Enrichment and signal-based modeling (e.g. layering web sentiment on financial metrics) are opening entirely new edges. - Consulting firms. Value was proven months ago. Now the conversation is about trust, reliability, and the ability to scale with end clients. - Retail & luxury. 2025 was a year with too many experiments. Now it’s more focus with fewer but sharper initiatives centered on tangible value for employees and customers. - Government & public sector. Security and trust remain the main friction. But governance frameworks are catching up, which is a key unlock for broader adoption. - New movers: travel & transportation, healthcare & pharma. A handful of focused use cases. Nothing flashy, but real improvements in UX and day-to-day operations. (Meanwhile Denis making sure everything scales)

Your open-source model's knowledge is stale. Baseten + Linkup fix that. Open-weight models like GLM-5, Kimi K2.5, and MiniMax 2.5 can reason, write, and orchestrate tool calls. But their knowledge is still frozen at training time. In production, that means higher hallucination risk and lower user trust. Linkup fixes this. Our search API returns fresh, structured, and source-backed results optimized for LLM consumption - from sub-second search with Linkup Fast to multi-step research with Deep Search. And that’s why we’re excited to partner with Baseten. Baseten is the best way to run these models at scale. Together, we make it extremely simple to keep them grounded: 1. Select a model on Baseten 2. define a search_web tool powered by Linkup ...and you're live! Baseten handles inference. Linkup handles retrieval. 👉 Full tutorial and side-by-side comparison in the comments

Last Thursday we hosted a Claude Code Community event at Linkup's offices in Paris and it was packed. Big thanks to - Nischay, Max and Romain for their demos - Claude Code builders and AI practitioners all fully tuned in, asking sharp questions and pushing the conversation forward. - Olivier, Thomas and Alexander for making it happen. If you missed this one, stay tuned for the next.

Today, Linkup adds support for x402, the open payment protocol developed by Coinbase. Here's what this means in practice: an AI agent can now call our search API without anyone having created an account first. No sign-up, no email verification, no credit card entry, no API key. The agent makes a request, pays in USDC, and gets its results - all over standard HTTP. This sounds like a small change, but it removes a fundamental bottleneck. Most APIs still require a human to provision access before an agent can use them. That's fine when a developer is setting up a tool once. It breaks down when you want agents to operate independently - spinning up sub-agents, delegating research tasks, running 24/7 without someone managing the billing relationship. x402 solves this by reviving the HTTP 402 status code (literally "Payment Required" - it's been in the spec since the 90s, unused). When an unauthenticated request hits a paid endpoint, the server responds with a price and a wallet address. The client signs a USDC transfer and retries. If the payment is valid, the server returns the resource. From the agent's perspective, accessing a paid API becomes as simple as accessing a free one. The only requirement is a funded wallet. Massive thank you to Coinbase and Stripe for building the payment infrastructure that makes this work. Their teams made it significantly easier to implement the protocol correctly and reliably. If you're building agentic workflows that need web search, this is a new way in - no account required. Full details in the blog post - link in the comments.
