Delx Commerce currency exchange rates API for agents at $0.001 USDC

Delx Commerce currency exchange rates API for agents at $0.001 USDC. Call when you need daily ECB FX rates (EUR/USD/BRL and other published pairs) with source attribution—not a live broker quote or trade execution. Returns bounded cross-rates via x402; informational only, no trading advice.

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.
