03How to choose
Start from the ranking above instead of guessing, then run a quick check of your own: take the top two providers, read their docs, and call each once for your actual use case. A 30-minute hands-on test in your stack tells you more than any single headline number, because the right unofficial API also depends on your budget and constraints, which the score deliberately leaves out.
