Start here if you're deciding what to build with Nevermined. Solutions tell you *what's possible*. Use cases tell you *what someone shipped*. Each page in this section walks through a real, productized pattern — what it monetizes, when to pick it, who's already running it, and the integration cost. If you're scoping a Nevermined integration and want to know "is this the right shape for what I'm building?", start here. One x402-protected endpoint hands out a quota-bearing API key. The provider keeps their own metering, no per-call settlement. Live in production with [Exa](https://exa.ai/docs/integrations/nevermined.md). Best when your service already has API keys with quotas. ## Why "Use Cases" is a separate section Nevermined started by monetizing **agents** — letting builders charge for the AI services they expose. But the same primitives also monetize **what agents pay for to get their job done**: third-party APIs, MCP tools, data feeds, anything an agent needs mid-task that a human would have paid for in a browser. That second class of integration looks different on the wire — often one purchase endpoint and the provider's existing metering everywhere else — and it deserves its own home in the docs. More use cases will land here as the patterns get productized. ## Related * [Solutions](/docs/solutions/api-providers) — the technical implementation guides behind each use case * [Payment patterns](/docs/integrate/patterns/fiat-payments) — the lower-level building blocks * [Nevermined x402](/docs/development-guide/nevermined-x402) — the protocol everything sits on
