Nexus now integrates Fetch.ai’s ASI:One model, giving developers a new way to power agents with Fetch.ai’s LLM directly inside the platform. The integration comes with a generous free usage plan, making it easy to start using right away.

This integration is the latest step in our ongoing collaboration with Fetch.ai. By making ASI:One accessible in Nexus, we’re lowering the barrier for developers to start building agents with Fetch.ai’s LLM technology — quickly, easily, and at no cost.

This update reflects one of Nexus’s core principles: openness. You’re never locked into a single provider. Instead, you can bring your own keys, try different models, and design agents around the options that best fit your needs. Adding ASI:One expands that choice and lowers the barrier for developers to build with Fetch.ai’s technology.

Free Plan Details and How to Get Started

ASI:One comes with a generous free tier, making it easy to start using right away:

• Token Limit: 640,000 TPM (tokens per minute)

• Request Limit: 3 RPM (requests per minute) / 500 RPD (requests per day)

How to get your ASI:One API key:

1. Visit fetch.ai and sign up for ASI:One. You can sign up with Google or by creating an ASI Wallet.

2. Once signed in, go to your profile settings at the bottom of the sidebar and click API Keys, or visit this link directly.

3. Click Create new key, type in a project name, then copy your API key. Note: this key will not be revealed again, so paste it into Nexus right away or save it somewhere secure.

You can access your API Keys in ASI:One via the profile menu on the bottom of the sidebar.

After that, simply add your API key in Nexus in your LLM configuration, select ASI:One, and you’re ready to power agents with Fetch.ai’s model. There are several ASI:One models accessible via the Fetch API, but we highly recommend using the asi1-extended model in setting up your LLM.

What This Integration Enables

Thanks to this integration, Nexus users can:

• Run agents powered by Fetch.ai’s ASI:One model directly inside Nexus.

• Start for free with a Fetch.ai API key and explore without friction.

• Build workflows that combine Fetch.ai models with other tools, datasets, and Nexus-native capabilities.

Nexus now supports sign-in with Google or Microsoft accounts, giving every new user a 30-day free trial. You can get started instantly — no complex setup required — and connect your Fetch.ai API key right away to build agents with ASI:One.

Together, free access to Nexus and Fetch.ai’s ASI:One model creates a seamless on-ramp for developers and teams to experiment with agentic workflows, test integrations, and see real results without the need for your own hosting or infrastructure.

For the broader ecosystem, this is another step toward making AI infrastructure more open, accessible, and interoperable.

Building the Agentic Future, Together

This integration marks the latest step in our collaboration with Fetch.ai, as we continue to expand what’s possible when combining data infrastructure with agent intelligence.

• Nexus in the Fetch.ai ecosystem: Nexus will become more visible and accessible to Fetch.ai users. By bringing Nexus directly into the Fetch.ai ecosystem, it will be easier for community members to get started, connect their data, and begin building agents powered by both platforms.

• Support for Fetch agents in Nexus: Agents created in the Fetch.ai platform will be integrated directly into Nexus. This will allow developers to design and deploy agents in Fetch.ai, then manage, query, and connect them with data sources inside Nexus — creating a seamless bridge between the two ecosystems.

Each enrichment to this collaboration will enhance accessibility to AI, building fair and transparent ecosystems that add value and create real-world impact by combining data infrastructure with agent intelligence.

Towards an Open Agentic Ecosystem

At Nuklai, our mission is to create an open, modular data infrastructure where agents, models, and tools can work across ecosystems. Adding Fetch.ai’s ASI:One model is a natural extension of that vision, giving developers another accessible entry point into agentic workflows.

Like our integration with io.net, this collaboration shows how Nexus serves as the connective tissue between ecosystems, making AI more open, decentralized, and usable.
