Microsoft Azure Cdn Rate Limits

Published throttling limits for the Azure CDN management API. This REPLACES the 2026-05-04 API Evangelist scaffold, which invented free/professional/enterprise request quotas and X-RateLimit-* headers that Azure does not emit. The real mechanism is Azure Resource Manager's token-bucket throttling, applied per region, per subscription, per service principal and per operation type — the Microsoft.Cdn resource provider inherits it. Limits and header names below are read verbatim from the Microsoft ARM throttling documentation.

Microsoft Azure Cdn Rate Limits is the machine-readable rate-limit profile for Microsoft Azure Cdn on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and note.

Tagged areas include Rate Limiting, Quotas, and Throttling.

Policies

Backoff
Honour Retry-After on a 429. Requests sent before the retry value elapses are not processed and a new retry value is returned.
Pre-emptive backoff
Read the x-ms-ratelimit-remaining-* header on every response and slow down before the bucket empties rather than after the 429.
SDK auto-retry
The first-party Azure SDKs in packages/microsoft-azure-cdn-packages.yml implement retry policies; Microsoft directs clients to the Retry guidance for Azure services.
Per-region accounting
Throttling is applied per region rather than per ARM instance, so the same subscription has an independent bucket in each region it addresses.
