>log in to commentClaude Code can write code, but it doesn't automatically understand your API workflows, business logic, dependencies, or execution context. apilabs.ai SuperContracts is an open-source, executable YAML contract layer that teaches AI coding agents how APIs and MCP tools fit together. Define multi-step workflows, chain API responses, validate results, enforce guardrails, and require approval for sensitive actions—all through reusable YAML contracts. Help Claude Code go beyond generating API calls to understanding, testing, and executing real-world API workflows. Watch the YouTube demo and explore the open-source SuperContracts repository.

apilabs.ai Supercontracts FAQ
What is Agent Security?+
Agent Security is a set of policy-driven guardrails that monitor and control AI-agent actions across IDEs, terminals and APIs, allowing deterministic ALLOW, DENY or human approval.
How do SuperContracts become executable?+
The YAML DSL compiles into runtime contracts that can test API responses, enforce policies, trigger approvals and execute the defined workflow.
Can apilabs.ai reach localhost or private APIs?+
Yes, it can connect instantly to local or private endpoints via ngrok or Cloudflare Tunnel without manual proxy setup.
What IDEs are supported for the security hooks?+
Cursor™, Claude Code™ and other AI IDEs can route actions through the MCP Gateway and use post-shell or eBPF hooks for enforcement.
How does the Request Studio differ from Postman?+
Request Studio combines AI-powered natural language query, testing and direct conversion to SuperContracts, whereas Postman is a separate testing client.
Is coding experience required to use apilabs.ai?+
No, business users can ask natural-language questions and run APIs via the AI Chat core, while developers can use the YAML contracts for deeper control.
