Rate Limiting on the PublicAPIs endpoint?

app          | pydantic_core._pydantic_core.ValidationError: 1 validation error for PublicAPIsResponse

It looks like there is some sort of rate limiting on the Public API request, might have something to do with the httpx user agent? Not sure if anyone has encountered this, as the endpoint is perfectly accessible through the browser.
