Per Google,
"Beginning on June 11, 2018, you’ll need to enable billing with a credit card and have a valid API key for all projects. This will give you the ability to scale easily with less downtime and fewer performance issues. In addition, we’re simplifying our 18 individual APIs into three products: Maps, Routes, and Places."

However, Google do not say anywhere whether it's a hard stop or not. What if I don't enable billing account and do not add credit card information. Will I still be able to access Google APIs such as map, directions, geocode after June 11, 2018?
