Geocoding — entry 054 of 80
MapQuest
MapQuest's Geocoding API converts addresses to coordinates and back, supporting batch requests of up to 100 addresses per call, with results returned as JSON (default), XML, or CSV. Now operated by System1 after MapQuest's 2019 sale by Verizon, the API shares a single key with MapQuest's directions, static-map, and search products. New accounts get 15,000 free transactions with no time limit, then metered pay-as-you-go at $0.0045/transaction, or fixed monthly plans starting at $119/month for 30,000 transactions.
