Free APIs With No Credit Card Required

Updated July 2026 · 103 APIs tracked · checked hourly

Entering a credit card for a "free" tier is a bad deal: one accidental overage and you're paying. Every API on this list has a genuine no-card free tier — either completely open (no key, no signup) or requiring only an email address. We set the bar at a free-tier score of 0.7 or above, which filters out any API that puts a credit card between you and the first successful API call. Results are ranked by composite uptime + speed + tier quality score.
