Utilito API Playground

Search the compact tool index, load one exact schema on demand, import a verified sample when available, then deliberately run one same-origin request. Nothing runs while you search, select, inspect, or follow a deep link.

Editing input synchronously invalidates every prior result, receipt, export, copy state, and download.
Hosted execution is fixed to same-origin POST /api/run. Schemas load from same-origin GET /api/tools/:id/schema after you select a tool. This page has no endpoint, method, header, credential, history, or storage controls.
Classify submitted API or MCP evidence locally without contacting an endpoint or retaining inputs.
