Overview

QuantCDN API 4.31.0

Unified API for QuantCDN Admin and QuantCloud Platform services

Rate limits

Per token. Each API token has a limit per organisation: by default 240 requests per minute. The limit counts after the token is validated, so tokens that share an IP address (for example Quant Cloud apps and CI runners) do not share a limit. An organisation can have a different limit (set per organisation or by subscription plan); contact Quant support to change it.
Unauthenticated requests. Requests that end without a valid token (no token, an invalid or expired token, public routes) have a coarse limit per client IP address: by default 600 requests per minute. A request with a valid token never counts against it and is never refused by it. A request with a valid token that is refused before the per-token limit runs (for example an organisation the token cannot use) still counts against the token.
KV per project. Some KV operations also have a limit per project, shared by every token: kv-admin 10 requests per minute (index create, delete and resume; upgrade; export create and resume; ledger declare, raise and drop), kv-erase 30 (ledger subject preview and shred), kv-verify 6 (ledger verify).
Responses. Over a limit the answer is 429 with a Retry-After header (seconds). KV routes answer the V2KvError body with code RATE_LIMITED and retryable true; other routes answer {“message”: “Too Many Attempts.”}. Rate-limited routes send RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset (IETF draft; Reset is seconds until the window resets) and X-RateLimit-Limit and X-RateLimit-Remaining on the responses of requests that reach a limiter, and X-RateLimit-Reset (Unix time) on a 429. A request refused before a limiter runs (for example a 401, 403 or 404 from an earlier check) can come back without these headers. When two limits apply, the headers describe the one with fewer requests left. Wait Retry-After seconds, then send the request again.
