description: >-
  The primary developer surface, the LLM Guard API, is self-hosted: there is no
  vendor-imposed rate limit. Throughput is bounded only by the resources of the
  deployment you operate (CPU/GPU, worker count, model load), and operators may
  add their own gateway-level limits. The commercial platform products
  (Guardian, Recon, Layer) run as managed services whose limits are governed by
  account agreements and are not publicly documented. No specific per-endpoint
  values are reconciled in this artifact.
notes: >-
  Self-hosted LLM Guard has no provider rate limit; tune Uvicorn workers and
  scanner selection for throughput. Commercial product limits depend on the
  Protect AI / Palo Alto Networks agreement; verify on reconciliation.

policies:
- name: Self-Hosted Throughput
  description: Scale LLM Guard horizontally and suppress unused scanners to raise effective throughput; no vendor quota applies.
- name: Backoff Strategy
  description: Clients should implement exponential backoff with jitter and honor Retry-After when fronting LLM Guard with a gateway or calling commercial endpoints.
