Your service is doing more than simple verification. Verification by its nature would result in a boolean. Your service is suggesting a better address (which is what I'd call normalization). e.g.
curl https://www.geteasypost.com/api/address/verify \
-u cueqNZUb3ldeWTNX7MU3Mel8UXtaAMUi: \
-d 'address[street1]=388 Townshende Ave' \
-d 'address[street2]=Unit 20' \
-d 'address[city]=San Francisco' \
-d 'address[state]=CA' \
-d 'address[zip]=94107'
{"address":{"street1":"388 TOWNSEND ST APT 20","city":"SAN FRANCISCO","state":"CA","zip":"94107"}}
"388 Townsend San Fran"
Edit - Yahoo is actually letting people pay very respectable rates for their PlaceFinder service now. This is great: http://developer.yahoo.com/boss/geo/
1) They are abusing the USPS api and charging access for it.
2) The USPS resolver sucks anyhow. "388 Townsend San Fran" yields an error. Google & Yahoo both correctly match it.
3) Their pricing is pretty expensive, imo.
