While not an API with multiple translations, there are sophisticated desktop software packages like "Accordance Bible" (https://www.accordancebible.com/ https://www.accordancebible.com/) that will let one view any chosen, supported, English translation side-by-side with the original language (usually Hebrew or Greek) for that same passage. The software also will follow quasi-word-for-word the text your cursor hovers in one view to the analog in the other view it's translated from or to. This shows there's been considerable effort in mapping the translations and original languages back and forth and making them easily accessible. For an example of a direct use of this feature, reference Chris Roseborough's "Fighting for the Faith" YouTube series where he often uses this feature of Accordance Bible, along with his knowledge of the original languages and the built-in original-language dictionaries and thesaurus to analyze heretical or erroneous interpretations and applications of biblical text made by what he deems the myriad "false teachers" in current "evangelical" preacher-dom. For example of use of this particular word-for-word feature look at the video shortly after https://youtu.be/tFeF04F8Tf8?t=828 https://youtu.be/tFeF04F8Tf8?t=828 (a critique of Joel Osteen's "prosperity preaching"). At around 14:01 in the video you'll start seeing the Greek text analogs highlight as the cursor drifts around the English text. In this section of the video he's not explicitly using the feature, but he often does ... hmmm, at around 16:30 or so he does, showing the original text for "I AM" and "do not be afraid." In any case, there's been much work in software such as "Accordance Bible" and others to make "translation mapping" more apparent, and to expose any "translation issues" ... this necessarily would require the user to be very familiar with the original languages. Chris Roseborough himself is very conservative (young-earth creationist; women should not be pastors; ... etc., many views that would not be popular). The most frequent targets of his criticism are those who preach "prosperity gospel" (e.g. Joel Osteen); those who believe apostles and prophets still exist and can write "scripture" today with as much authority as the original Hebrew and Greek texts (e.g., New Apostolic Reformation / NAR / Bethel / Hillsong); those who believe they can "decree and declare" God to steer hurricanes, heal people of their sicknesses (I don't think C.R. would object to the possibility of healing, just that there are no guarantees this side of eternity and God's purpose isn't to alleviate all suffering here and now), cause career success and wealth, and that believe if you aren't blessed you don't have enough faith.
