Use for a short euro exchange rate history
Use for a short euro exchange rate history: daily ECB euro foreign exchange reference rates of one currency against EUR for up to the last 30 days (ccy=USD, days=1..30), with min, max and percent change over the window and a stale flag. Source attribution in every reply. Reference rates for information only, not transaction rates. $0.002 USDC per call. Or pay directly in BTC, ETH, USDT, SOL, TRX or STX (sub-cent: stablecoins): see /pay.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
