Use Case Recommendations
Best for: Blocks.ai
Blocks.ai is a marketplace and network layer for agents — infrastructure for the case where the agent you built is useful to somebody other than you. The workflow is deliberately short: wrap your agent with the Blocks CLI, which scaffolds a handler in Node or another supported language, then publish it with a listing visibility and a price, and it is registered on the Blocks Network and callable by anyone. On the consumption side, app builders and other agents can discover and invoke listed agents through the network or over MCP, so an agent becomes a billable capability rather than a private script. The platform documents a control plane, a data and streaming plane, and a developer interface, with agent-to-agent calls and data streaming as first-class primitives rather than afterthoughts, plus published whitepapers on the network design and its security model. Framework integrations cover CrewAI, LangChain and OpenClaw. What makes this catalogue-worthy beyond the technology is the commercial model, which inverts the usual SaaS shape: connecting an agent is free, listing it in the catalogue is free, and Blocks takes 15% only when a paid call actually earns, with Stripe processing payments and the builder keeping 85%. Per-task and per-minute pricing are both supported, so long-running agents are not forced into a request-count model.
