Sometime if you use Google Drive, Google Docs, Google Sheets, Dropbox or similar free cloud storage services to store your input files, you may get
Too Many Requests in or
Access Denied errors after previously successful calls. Cloud services are throttling requests to prevent frequent access to their files by using this type of protection. Paid plans like Google Workspace provide better support for frequent access but still throttling all incoming requests too.
To solve this issue, PDF.co can use its built-in secure input url cache. Just add
cache: prefix to your input url to enable caching.
This will tell PDF.co to cache file from the url for next 15 minutes. Instead of re-requesting your url every time, it will use its cached version. This will prevent from getting
Too Many Requests error.
