Cache hit, miss and bypass counts
const url = 'https://api.nsin.cloud/analytics/cache?domain=example.com&period=3h';const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url 'https://api.nsin.cloud/analytics/cache?domain=example.com&period=3h' \ --header 'Authorization: Bearer <token>'hit_rate is hits / (hits + misses) — bypasses are excluded from the
denominator, since a bypassed request was never a caching candidate.
bypass_reasons breaks down why requests bypassed the cache.
Authorizations
Section titled “Authorizations ”Parameters
Section titled “ Parameters ”Query Parameters
Section titled “Query Parameters ”The domain name (for example example.com). These endpoints take the
domain as a query parameter rather than a path segment.
Example
example.comTime window, ending now. Buckets are hourly up to 24h and daily for
7d and 30d. An unrecognised value falls back to 24h.
Narrow to one subdomain. Matches the exact host, any subdomain of it, or
a bare label — so example.com matches api.example.com, and api
matches api.example.com, but exam matches neither.
Narrow to a URL path prefix.
Responses
Section titled “ Responses ”Cache counters.

hits / (hits + misses); 0 when there were no cache lookups.

Examples
{ "error": "domain is required"}Missing, malformed, revoked or expired API key, or a key whose owning
user row is gone. A key whose owning account has merely been deactivated
is not this: that is 403 with code: account_suspended, because the
credential itself is intact and re-issuing it changes nothing.

Examples
{ "error": "rate limit exceeded"}The process holds no ClickHouse client at all - the connection was never opened at startup. It is built once and never rebuilt, so this state lasts until the backend restarts.
It is NOT what you get when the store is merely down, and that is the
trap. Startup opens the client and pings it as a separate step; a failed
ping is logged and the client is kept, so a ClickHouse that was
unreachable at boot still leaves a usable handle behind and this 503
stays rare. Every failure at query time answers 500 instead - the
store unreachable, or a query outrunning its timeout of 10s for windows
up to 24h, 20s for 7d, 45s for 30d - carrying either
{"error": "query failed"} or a “Could not load analytics right now”
message.
So retry on 500 exactly as you retry on 503. On the analytics endpoints a 500 nearly always means the store could not answer, not that your request was wrong.
