Find semantic gaps
Catch contracts that validate cleanly but leave agents guessing when, why, and how to call an operation.
OpenAPI intelligence for agentic systems
Your API is valid.
Is it agent-ready?
Paste, upload, or import a public OpenAPI URL, then measure whether an AI agent can discover the right operation, construct it correctly, and interpret the result safely.

From contract to confidence
A linter checks syntax.
This checks usefulness.
Every result is traceable to a stable rule, an exact JSON Pointer, and a clear impact on agent behavior.
Apply safe repairs
Receive RFC 6902 patches only when a change can be derived mechanically—never invented business semantics.
Shape MCP tools
Generate focused candidate tool bundles with collision-safe names, input schemas, and explicit mutation risk.
Free contract check
See what an agent sees.
Paste, upload, or import a public URL for an OpenAPI 3.0 or 3.1 contract. Your document is processed in memory and never saved.
Browser-safe URL import

Explore three audit outcomes
Load a focused contract, run the free score, and compare what passes with the gaps an agent would encounter.
Ready when your contract is
Run the score to reveal structural gaps, ambiguous operations, unsafe mutations, and weak response contracts.
