Assertwise Lab / Rate limiting

Rate limiting

API rate-limit indicator (light, max. 10 requests)

A quick indicator whether rate limiting is visible on an endpoint. It is explicitly not a rate-limit or load test.

RUNS ON OUR SERVER

Limits: 10 checks per hour per IP, max. 10 light requests per run, ports 80/443 only, private and internal addresses are blocked. User-Agent: AssertwiseCheck/1.0. What we send and store.

Interpreting the result

A 429 within 10 requests means a strict limit is enforced. RateLimit headers (IETF draft) or X-RateLimit-* headers mean limits are documented to clients. Neither proves the limit is effective per user, per token or against distributed attacks – testing that properly needs an authorized test with controlled load, which we do in API security engagements.
