Versioned pricing intelligence
AI pricing changes. Your costs don’t break.
Every rate is a versioned record — sourced, dated, and verified. When a provider changes a price, your historical costs re-resolve against the correct version. Nothing is silently rewritten.
Versioned
Every rate carries an effective date and a full change history.
Sourced
Collected from official pages and APIs, then normalized.
Verified
A human approves changes before they ever affect accounting.
