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.

curl \
  -X POST \
  -H "Content-Type: application/json" \
  -H "X-Auth-Email: CLOUDFLARE_EMAIL" \
  -H "X-Auth-key: CLOUDFLARE_API_KEY" \

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" \
