List Cache Policies

List all configured cache policy resources.

Parameters

Responses

• 200: OK
• [].id (string, required): Resource ID, as assigned by the active resource source.
• [].revision (integer, required): Monotonic resource revision: the etcd mod_revision of the entry, or the load generation in file mode.
• [].value (object, required): Stored cache policy configuration.
• allOf variant 1
• [].value.applies_to (string, optional): Free-form scope. Supports "all", "model:<name>", and "api_key:<id>". See parsed_applies_to.
• [].value.backend (object, optional): Cache backend used for matching requests.
• allOf variant 1
• [].value.enabled (boolean, optional): When false, the cache gate skips this policy. Allows operators to stage a rule before enabling it.
• [].value.name (string, required): Operator-facing name that surfaces in metric labels and cache headers.
• [].value.purge_generation (integer, optional): Invalidation counter. Entries are readable only while their stored generation matches; a purge bumps this value, making every earlier entry unreachable at once. Managed by the purge operation — not set directly. Full-document updates must carry the current value forward: writing a lower (or omitted, i.e. 0) value re-exposes entries stored under that earlier generation until their TTL passes.
• [].value.scope (object, optional): Sharing boundary for entries created under this policy: api_key (default) keeps entries private to the caller that created them; env shares them across the environment.
• allOf variant 1
• oneOf variant 1: Per API key
• oneOf variant 2: Environment-wide
• [].value.semantic (object, optional): Embedding-similarity matching. Absent: the policy matches exactly-identical requests only.
• allOf variant 1
• [].value.semantic.embedding_model (string, required): Name of the embedding model used to embed requests. The model must exist in the same environment and carry an embedding block; its dimensions value fixes the vector size for this policy's entries.
• [].value.semantic.embedding_timeout_ms (integer, optional): Per-call deadline for the embedding request in milliseconds. 0 or absent disables the embedding-specific deadline. On timeout the request proceeds to the upstream uncached.
• [].value.semantic.max_entries (integer, optional): Upper bound on stored entries for this policy on the memory backend; the oldest entry is evicted first. Shared backends bound growth by TTL instead and ignore this value. The ceiling keeps the per-request similarity scan and the per-policy vector memory bounded; workloads needing more entries belong on a shared backend.
• [].value.semantic.threshold (number, required): Minimum cosine similarity for a stored entry to be served, in [0, 1]. Higher is stricter. Values below 0.9 noticeably increase wrong-answer risk for most embedding models.
• [].value.ttl_seconds (integer, optional): Cache entry TTL in seconds.
• 401: Missing or invalid admin key
• error_msg (string, required): Human-readable error message.
• 500: Configuration store operation failed Response fields (application/json): identical to GET /admin/v1/cache_policies, response 401 above.
