Web Tools API is obsolete

I have not found any PHP projects that implement the API in PHP except this one which is more of a script than a library

However I did come across this project for UPS which mentions it was partly generated using Jane using the published UPS OpenAPI spec.
https://github.com/ShipStream/ups-rest-php-sdk#development

USPS publishes OpenAPI spec files for their API. We could use that to generate most of the code for a library using Jane.

They may have turned off the Web Tools API last night. My rate requests are not getting responses.

They apparently turned Web Tools back on. Watchdog has 200 status on USPS responses since 14 Jan 2025.
