Free APIs With No Credit Card Required

Updated August 2026 · 131 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.

Frequently Asked Questions

Why do some free APIs ask for a credit card?

Credit card requirements on free tiers are mostly about fraud prevention and identity verification, not about charging you. Large-scale API abuse (scraping, bot traffic, DDoS) is expensive for providers. A card on file dramatically reduces abuse because it ties the account to a real person. The risk to you is auto-upgrade: if you don't read the fine print, a usage spike could trigger a charge. Our filter here (free_tier_score ≥ 0.7) excludes any API where a card is required to access the free tier — you get a genuine free tier or just an email signup.

What's the actual risk of entering a credit card for a 'free' API?

The main risks are: (1) automatic upgrades if you exceed limits — most providers do warn you, but alerts can be missed; (2) forgetting to cancel if you stop using the API; (3) the provider changing its pricing model. If you do use an API that requires a card for its free tier, set a billing alert and calendar reminder to review your account monthly. The APIs on this page avoid this entirely — none require payment information to get started.

Is a 'free key, no credit card' API truly free forever?

For most providers, yes — within the stated limits. Open-Meteo, Hacker News, and Wikipedia have been free for years with no sign of change. For VC-backed startups offering free tiers, there's always a risk of policy changes. We track status changes in our events feed — if an API moves from free to requiring a card, it shows up in our graveyard section. The safest bets are APIs backed by governments (NOAA, ECB rates), academic institutions, or open-source foundations.

How do I find which APIs on this list fit my volume needs?

The free tier text on each card shows the call limit. For a hobby project making a few hundred calls a day, almost any API here works. For a side project getting moderate traffic (a few thousand calls/day), filter for 'no key' APIs (Open-Meteo at 10,000/day, Binance at 1,200/min, etc.) or high-limit key APIs (Mapbox at 100,000/month, CryptoCompare at 100,000/month). For production at scale, most of these free tiers will be insufficient and a paid plan is the right answer.
