Querying Workers Metrics with GraphQL

In this example, we're going to use the GraphQL Analytics API to query for Workers Metrics over a specified time period. We can query up to one week of data for dates up to three months ago.

The following API call will request a Worker script's metrics over a one day period, and output the requested fields. Be sure to replace CLOUDFLARE_EMAIL and CLOUDFLARE_API_KEY with your email and API credentials, and adjust the datetimeStart, datetimeEnd, accountTag, and scriptName variables as needed.

API Call

CLOUDFLARE_EMAIL=<CLOUDFLARE_EMAIL>
CLOUDFLARE_API_KEY=<CLOUDFLARE_API_KEY>
PAYLOAD='{ "query":
"query GetWorkersAnalytics($accountTag: string, $datetimeStart: string, $datetimeEnd: string, $scriptName: string) {
viewer {
accounts(filter: {accountTag: $accountTag}) {
workersInvocationsAdaptive(limit: 100, filter: {
scriptName: $scriptName,

curl \
-X POST \
-H "Content-Type: application/json" \
-H "X-Auth-Email: CLOUDFLARE_EMAIL" \
-H "X-Auth-key: CLOUDFLARE_API_KEY" \
--data "$(echo $PAYLOAD)" \
https://api.cloudflare.com/client/v4/graphql/

The results returned will be in JSON (as requested), so piping the output to jq will make them easier to read, e.g.,:

curl \
-X POST \
-H "Content-Type: application/json" \
-H "X-Auth-Email: CLOUDFLARE_EMAIL" \
-H "X-Auth-key: CLOUDFLARE_API_KEY" \
--data "$(echo $PAYLOAD)" \
https://api.cloudflare.com/client/v4/graphql/ | jq .
