  Full docs-surface search across www.vipkid.com, www.vipkid.com.cn, www.vipteacher.com
  and teach.vipteacher.com on 2026-09-04. No API reference exists in which limits could
  be published.
provider: VIPKid
limit_count: 0
summary: >-
  No rate limits are documented, because no public API is documented. There is no API
  reference, no developer portal and no machine-readable contract on any VIPKid host, so
  there is no published throttle, quota, burst allowance, exhaustion status code or
  rate-limit response header to record. This is an honest zero, not an unchecked field.
rate_limits: []
response_headers:
  observed: []
  note: >-
    No unauthenticated VIPKid API endpoint could be called to observe headers. The only
    API-shaped host referenced by the site's own JavaScript is
    https://merlin-tl.vipkid.com.cn/api/experiment/treatment, an internal A/B-testing
    endpoint used by the web app; it returns 502 to an anonymous GET and is neither
    documented nor offered to third parties, so it is not registered as an API here.
