Hello,
Thank you for your query and we are so sorry about the trouble this must have caused.
Would you kindly change the API key on a private window or incognito and check if the 404 still occurs? If it does, you may have to add the key manually in order to make this work and let search engines use this to verify your site:

Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
