Denial-of-Wallet
Attacks

Denial-of-wallet is the attack unique to the AI era: no exploit, no stolen key — an abuser automates your free tier and the inference bill is the payload. Vectoral catches it on both ends. The cost/velocity signal layer flags inhuman token bursts, robotic timing, and always-on patterns at score time; spend alerts warn you the instant a single account or your whole tenant crosses a threshold; and one-click blocking stops the drain before the next call is billed.
