The developer hub's own machine-readable index (llms.txt) lists exactly one guide page and five API reference pages, and none of them is a limits, quotas, or throttling page; the reference HTML contains no occurrence of "rate limit"; and neither published OpenAPI declares a 429 response, a Retry-After header, or any X-RateLimit-*/RateLimit-* response header on any of the five operations. The only volume control expressed anywhere in the contract is a per-request `limit` query parameter on GET /conversations, described as "Limit of results to return (default system limits exist)" — an unquantified reference to limits that are never published. Nothing could be observed live either: the API host api.cuein.ai does not resolve (see lifecycle/), so no runtime header could be probed. An honest zero. evidence: - url: https://cuein-api.readme.io/llms.txt status: 200 detail: documentation index — no rate-limit page listed - url: https://cuein-api.readme.io/reference status: 200 detail: no "rate limit" string in the served document - url: https://cuein-api.readme.io/reference/getanswer.md status: 200 detail: full OpenAPI for the Answers API inlined; declares only 200 and 400 undocumented_signal: parameter: limit operation: openapi/_original/cuein-insights-openapi.json#Retrieve insights for multiple conversations provider_text: Limit of results to return (default system limits exist)
