# Querying Workers Metrics with GraphQL

Last updated Aug 25, 2026|Copy as Markdown|[View as Markdown](https://4f1c5cd2.previews.developers.cloudflare.com/analytics/graphql-api/tutorials/querying-workers-metrics/index.md)|[Agent setup](https://4f1c5cd2.previews.developers.cloudflare.com/agent-setup/)

In this example, we are going to use the GraphQL Analytics API to query for Workers Metrics over a specified time period. We can query up to one month 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_ACCOUNT_TAG>` and `<API_TOKEN>`[1](#user-content-fn-1) with your API credentials, and adjust the `datetimeStart`, `datetimeEnd`, and `scriptName` variables as needed.

## API Call

```bash
echo '{ "query":
  "query GetWorkersAnalytics($accountTag: string, $datetimeStart: string, $datetimeEnd: string, $scriptName: string) {
    viewer {
      accounts(filter: {accountTag: $accountTag}) {
        workersInvocationsAdaptive(limit: 100, filter: {
          scriptName: $scriptName,
          datetime_geq: $datetimeStart,
          datetime_leq: $datetimeEnd
        }) {
          sum {
            subrequests
            requests
            errors
          }
          quantiles {
            cpuTimeP50
            cpuTimeP99
          }
          dimensions{
            datetime
            scriptName
            status
          }
        }
      }
    }
  }",
  "variables": {
    "accountTag": "<CLOUDFLARE_ACCOUNT_TAG>",
    "datetimeStart": "2022-08-04T00:00:00.000Z",
    "datetimeEnd": "2022-08-04T01:00:00.000Z",
    "scriptName": "worker-subrequest-test-client"
  }
}' | tr -d '\n' | curl --silent \
https://api.cloudflare.com/client/v4/graphql \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data @-
```

The results returned will be in JSON (as requested), so piping the output to `jq` will make them easier to read, like in the following example:

```bash
... | curl --silent \
https://api.cloudflare.com/client/v4/graphql \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data @- | jq .
