Data APIs

77 services

Most data APIs here meter requests per day or per month, and the period changes what fits: a daily cap absorbs steady traffic, a monthly one runs out early after a spike. IP geolocation is the largest group. IPinfo allows 50,000 requests a month, IPTrace 50,000 lookups, ipapi 30,000 a month and 1,000 a day, and DB-IP, IPLocate and The IP API 1,000 a day. ip-api needs no key but is for non-commercial use, at 45 requests a minute per IP, and its free endpoint serves plain HTTP only.

Exchange rate APIs vary widely: exchangerate-api.com gives 1,500 requests a month with daily updates, CurrencyFreaks 1,000, currencylayer 100, and UniRateAPI lists unlimited calls. Validation APIs are tighter still, with numverify at 100 phone checks a month, veriphone at 1,000, vatcheckapi.com at 150 VAT checks and vatnode at 100. Finance and news data often come delayed or with short history: News API returns articles with a 24-hour delay at 100 requests a day, finlight with a 12-hour delay, and ROIC.ai limits history to 2 years.

Check the license terms as well as the quota. BrandIcons and FxRatesAPI require attribution, Currencyapi is for personal use only, and some smaller APIs go offline without notice, so cache responses and keep a fallback provider for anything your app depends on.
