OCAPI is a fairly robust API, however if your site is still on Pipelines architecture you may have a harder time integrating your existing customizations with OCAPI. In those cases use synthetic APIs and migrate that functionality to OCAPI at a later date. CCAPI layer in beta seems promising, but it is too early to judge the extent in which it will support speedy headless storefronts.
