## Terms of Service

The agreement between you and Onto covering use of our APIs, SDKs, MCP server, dashboard, and any related services.

In preparation

Waiting on the service-level question. We won't commit to an uptime figure we haven't measured for long enough to stand behind, and the rest of the document depends on where that line lands.
