Answer 1

Two things caught my attention with your request:

1. The recipient address doesn't contain a state value. I'm not completely sure whether it's required by FedEx, but many carriers do require the state code.
2. The package dimensions are 100x100x100. According to http://images.fedex.com/us/services/pdf/packaging/GrlPkgGuidelines_fxcom.pdf , this exceeds the max. girth restriction and thus you would need to use FedEx Freight, which is a different API. This would explain the "no valid services" error.

Answer 2

For me, issue was that the FedexRateServiceRequest requires Zip, CountryCode AND State. Without state I got the same error.

rate_request.RequestedShipment.Recipient.Address.StateOrProvinceCode = 'CA'
