How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalized JSON response containing the current exchange rate(s) for the requested currency pair(s), sourced from public FX data providers with edge caching and multi-source fallback for reliability.
Example use cases
Real-time currency conversion for invoicing
“I'm invoicing a client in Japan — what's the current JPY to USD exchange rate so I can calculate how much to charge in dollars?”
Travel budget FX check
“I'm heading to London next week — can you get me the latest GBP to USD rate so I can figure out my spending budget?”
Automated forex rate enrichment for fintech app
“Fetch the current EUR to USD exchange rate for me — I need to update the FX rates in my app without setting up an account or API key.”
Technical details
Endpoint
GEThttps://x402.santyvv.com/api/fx/rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live FX rates without account registration or API key management, especially in agentic or automated workflows where keyless micropayment access (x402/USDC on Base) is preferred over subscription-based forex APIs. Ideal for low-frequency spot lookups where paying $0.01 per call is more practical than maintaining a subscription.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Rate data temporarily unavailable from all upstream sources — returns error or stale cache notice
- Invalid or unsupported currency pair — returns error indicating unsupported pair
- Network timeout or edge cache miss — may return delayed response
