Everything your API contract needs
From the first conversation to production validation — Beavy keeps your contract honest.
Define contracts
Describe the API in plain English once — Beavy locks that in as ground truth, whoever writes the code five prompts later.
Validate real endpoints
Catch a quietly renamed field the moment it ships — whether your AI assistant did it three prompts ago or backend did it this morning.
Serve mocks instantly
Whoever's waiting on the backend — a teammate or your own future self — gets a real mock to build against today.
Driven via MCP
Works inside the AI tools you already use — nothing new to learn.
Encrypted credentials
Beavy encrypts every API key you add at rest. Validate your real endpoints without exposing your credentials.
