LiteLLM
LiteLLM proxy provides a unified API across LLM providers. Waldur manages the full virtual key lifecycle -
provision, rotate, pause, restore and terminate - from marketplace orders, and reports per-resource input
and output tokens plus USD spend from LiteLLM’s own daily spend table. Waldur limits are mirrored onto each
key as budget, TPM and RPM caps so a burst between reporting cycles cannot outrun metering, and keys can be
restricted to a per-offering model allowlist.
