	// contains filtered or unexported fields
}

API can register a set of endpoints in a router and handle them using the provided storage and query engine.

func NewAPI

func NewAPI(
	qe *promql.Engine,
	q storage.Queryable,
	configFunc func() config.Config,
	flagsMap map[string]string,
	readyFunc func(http.HandlerFunc) http.HandlerFunc,
	db func() TSDBAdmin,
	enableAdmin bool,
	logger log.Logger,
	remoteReadSampleLimit int,
	remoteReadConcurrencyLimit int,
	remoteReadMaxBytesInFrame int,
	CORSOrigin *regexp.Regexp,
	runtimeInfo func() (RuntimeInfo, error),
	buildInfo *PrometheusVersion,
) *API
