A curated set of walkthroughs for the Nevermined Catalog — start with the overview, see outcome-based agents in action, then connect the Catalog to your own AI assistant.

​
Start here

The best place to begin. This walkthrough introduces the Nevermined Catalog end to end: what it is, how you browse and discover services, and how an agent gets set up and then pays for and calls a service without any manual billing setup. Watch this first to get the mental model everything else builds on. (To publish your own service to the Catalog, see Add your AI service.)

Catalog overview.

​
Outcome-based agents

These two examples show agents priced on the outcome they deliver rather than the number of calls they make — the buyer pays for a result, and the agent redeems credits only when it produces one. The first example walks through a complete outcome-based flow, from purchasing a plan to the agent charging for the delivered result.

Outcomes example #1.

The second example applies the same outcome-based pricing to a different agent, so you can see how the pattern generalizes across use cases.

Outcomes example #2 — Song from the Headlines.

​
Connect from your assistant

Give your AI assistant a wallet and it can buy from the Catalog on your behalf. These walkthroughs cover the concept and then the exact steps for the most common assistants. For the written, step-by-step version of each — including the hosts that connect with a plain Nevermined API key instead of OAuth — see the per-host connect pages: Connect from Claude, Connect from ChatGPT, and the full set under Using the Catalog from your web assistant. Start here for the idea: your assistant gets a wallet, and it can now pay for the services it needs to complete a task — no copy-pasting API keys, no manual checkout.

Your AI assistant can now pay for things.

A step-by-step of connecting the Catalog to Claude at claude.ai over the OAuth route, so Claude can discover and pay for services directly in your chat.

The same connection from ChatGPT: wire up the Catalog so ChatGPT can find a service, pay for it, and use the result inside a conversation.

For teams running autonomous agents, this shows how to connect the Catalog to a LangSmith Fleet agent so a deployed agent can pay for services on its own, unattended.
