Spot by Flexera · Rate Limits

Flexera Rate Limits

Spot.io / Flexera does not publish per-second numeric rate limits for the public Spot API at api.spotinst.io. Bearer-token authenticated requests are subject to standard 429 throttling and an X-Request-Id is returned for correlation. Bulk operations (large cluster updates, savings reports) may queue.

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

It captures 1 rate-limit definition, measuring varies.

Limit state is signalled in the requestId and retryAfter response headers, 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 3 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Autoscaling, Cloud Infrastructure, Cost Optimization, Kubernetes, and Spot Instances.

not publicly published; standard 429/503 throttling applies

Policies

Backoff Strategy
Clients should implement exponential backoff with jitter on 429/5xx and honor Retry-After when present.
Bulk Operation Queueing
Long-running operations (cluster scale-out, commitment optimization runs) are asynchronous; poll the operation endpoint rather than retry the originating request.
Per-Account Tokens
API tokens are scoped to the Spot account; rotate via the console; revoking a token deauthorizes immediately.
