Tongji Rate Limits

The Tongji University Open Platform publishes one rate-limit policy that applies uniformly across its interfaces: a token-bucket limiter at 50 requests per second, counted per application, per IP and per concurrent request. Anonymous interfaces are limited on IP alone at the same rate. Some interfaces carry their own tighter limit, stated in that interface's own documentation page.

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

It captures 3 rate-limit definitions, measuring requests-per-second.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

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

Applies to the thirteen interfaces documented as 无需授权可直接访问, which need no credential and are therefore limited on source IP alone.

Individual interfaces may declare a tighter limit in the 备注 section of their own documentation page; the platform states these override the default.

Policies

Token caching
Cache the access_token for its 7200-second lifetime on the application side. Re-requesting a token per call risks rate limiting or a temporary block.
Quota increase
Contact the Tongji University Information Office; higher limits are granted case by case, not self-service.
Backoff Strategy
Exponential backoff with jitter on 429.
