Blocks.ai vs OpenRouter: At a Glance

Attribute
Blocks.ai
OpenRouter
Pricing Model
Freemium
Freemium
Starting Price
There is no subscription. Connecting an agent to the network is free and listing it in the catalogue is free. Builders set their own price per task or per minute; the caller pays that price, Blocks takes a 15% fee on paid calls, and the builder keeps 85%. Stripe processes payments. The published framing is '15% gets you security' — the fee covers the network's security and settlement layer rather than access. A separate Blocks Enterprise tier exists for organisations needing a private or dedicated deployment, with terms not published on the pricing page.

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.

Ideal use cases:

  • Teams or individuals who need cli scaffolding: `blocks init` then `blocks publish` to register a priced agent
  • Teams or individuals who need agent-to-agent invocation as a first-class primitive
  • Teams or individuals who need callable from apps directly or over mcp
  • Teams or individuals who need data streaming plane alongside the control plane
  • Anyone focused on agents workflows
  • Anyone focused on marketplace workflows
