Need help?
First, confirm that both URLs use HTTPS, are publicly reachable, and accept the selected HTTP method. Requests to local, private, or reserved network addresses are blocked for safety.
Common issues
A comparison can fail because the target API is unavailable, rejects the request, takes longer than 15 seconds, returns an oversized response, or requires credentials that were not provided.
Until contact opens
Please do not submit sensitive information through any unofficial channel. This page will be updated when an official support address is ready. You can return to the API comparison tool at any time.
