API Builder
The AI Agent's API Toolkit
Define REST APIs in a structured spec. Generate type-safe clients, server stubs, and tests. Use the compiler to verify correctness. Ship on the first try.
Spec → Generate → Compile → Ship
Why agents choose API Builder
Compiler as oracle
Generated code won't compile until your implementation matches the spec.
Explicit data shapes
Every field, type, and relationship defined upfront. No guessing.
First-try success
Agents using API Builder implement APIs correctly without iteration loops.
