University Of Macau Rate Limits

The University of Macau Data and Open Data API Platform enforces limits at the Azure API Management gateway in front of api.data.um.edu.mo, and documents the two failure modes on its own Response Codes page: 403 "Quota Exceeded — out of call volume quota for your subscription within a given time period" and 429 "Too Many Requests — rate limit is exceeded". What it does not publish is the numbers. The product policy that carries the actual call-volume quota and rate-limit window is not readable without a UMPASS sign-in, so a developer cannot size an integration before subscribing. The 403 message does carry a countdown — "Quota will be replenished in 00:49:11" — which means the replenishment interval is discoverable only by exhausting it.

University Of Macau Rate Limits is the machine-readable rate-limit profile for University of Macau on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring calls and requests-per-window.

The profile also includes 2 backoff/retry policies defined and response codes documented for quota_exceeded and throttled.

Tagged areas include Education, Higher Education, University, Open Data, and Rate Limiting.

Policies

Backoff strategy
Treat 403 and 429 as retryable and back off. Parse the replenishment time out of the 403 message body, because no Retry-After header is sent. Prefer paged reads with an explicit pagesize over unbounded /all sweeps — pagesize is capped at 100 and defaults to 100.
Pagination as a rate control
Collection responses cap at 100 records. Supply count first to learn _size and _total_pages, then page deliberately rather than polling.
