IIRC the reason they don't (can't?) provide a search API directly is because they're pulling from other search sources, e.g. Bing, and can't provide an API without licence violations.
Agreed that a DDG API would be pretty great, though.
IF they wish for an API, I think brave search supports API because they are an independent search index.
