Why Holdify?

Holdify vs. The Old Way

Traditional API management monitors usage. Holdify enforces budgets. The difference? Your margin.

The Old Way

Identity & Request Counting

  • Count requests after they happen
  • Send alerts when limits exceeded
  • Hope customers pay their bills
  • Chase revenue after it's lost

Holdify

Financial Enforcement

  • Block requests before they cost money
  • Return 402 when budget hits zero
  • Customers prepay with wallets
  • Protect revenue in real-time
