ECB FX Rates for Agents
Currency exchange rates API for agents using ECB reference data at $0.001 USDC. Call when you need daily 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.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
