Their website looked good, and their Startup plan looked promising for Crypto API data. Review collected by and hosted on G2.com.
Signed up for CoinAPI Startup plan ($79/mo) expecting a hard 1,000-credit daily limit. Instead, it defaults to allowing overages with no real-time block — extra requests get processed during short enforcement windows, then you get a "Quota Exceeded" email after the billable damage is done.
First day: bulk pull → 7,252 extra credits → $124.06 surprise charge (157% add-on). Spend Management hard cap is off by default; you must enable it manually post-signup.
Feels like a billing gotcha: market fixed quota, let users overrun unknowingly, bill later.
Other APIs enforce limits properly. Disputed charge as not as described.
