How to call it
Send one POST to api.upapi.io/email-read-verification-link-graph.post with your key in the X-Api-Key header and the parameters below as a JSON body. Each call spends 1 weighted unit of your monthly quota. The operation times out after 310 seconds. Responses are not cached; every call runs the operation.

- number — Max seconds to poll
- followRedirects
- boolean — Follow click-tracker redirects to resolve the actionable URL
