Waxell · Rate Limits

Waxell Rate Limits

Waxell exposes two related rate-limiting surfaces. The Observe REST API enforces tenant-scoped request limits (per `wax_sk_` API key) and returns HTTP 429 when exceeded. Independently, the Waxell governance engine itself emits "throttle" decisions through the policy_check endpoint to slow down or block agents under runtime cost or rate-limit policies — agents see this as a `PolicyViolationError`. Numeric ceilings are not publicly documented.

Waxell Rate Limits is the machine-readable rate-limit profile for Waxell on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring varies.

Limit state is signalled in the requestId response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and unauthorized.

Tagged areas include Rate Limiting, AI Agent Governance, and Observability.

Limits

Observe API requests (per API key) key
varies
see /docs/observe/api/rate-limits (gated)
Tenant-scoped throttle attached to the wax_sk_ key; numeric ceilings not published.
Policy check throttling account
varies
governed by configured Rate Limit / Cost Management policies
Governance policies can return a `throttle` decision that is enforced inside the SDK.
Runtime cost-budget throttle account
varies
configurable budget, raises PolicyViolationError when exceeded
Cost policies block or throttle runs when configured token / dollar budgets are exceeded.

Policies

PolicyViolationError on throttle/block
Throttle and block decisions raise `PolicyViolationError` inside the Waxell SDK; callers should catch and back off.
Decision actions
The policy engine returns one of seven actions — allow, warn, redact, throttle, block, skip, retry — only the latter three are throttle-equivalent.
Mid-execution governance
With `mid_execution_governance=True`, policies are re-evaluated between agent steps so long-running agents can be throttled mid-run.
Kill switch
Operators can flip a kill switch policy that immediately blocks all runs for an agent or tenant.
Retry guidance
Standard exponential backoff is recommended on HTTP 429; `retry_after_seconds` may be returned on policy decisions.
