How this service works
Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.
Output
Returns exchange rate data for the specified base currency against one or more quote currencies, optionally scoped to a historical date. The response includes numeric rate values for each currency pair requested.

Real-time multi-currency rate lookup

Historical FX rate for financial reporting
“What was the EUR to USD and EUR to JPY exchange rate on March 15, 2024?”
Cross-currency portfolio valuation
“I need today's exchange rates for GBP as the base currency against USD, AUD, and CAD for my portfolio report.”
Technical details
Endpoint
GEThttps://mcp-x402-discovery.onrender.com/x402/fx-rateWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call FX rate lookups without a subscription, especially inside crypto-native or x402-enabled agent workflows. It is well-suited for agents that need to integrate FX data alongside crypto, RWA, SEC, or housing compliance data from the same ScriptMasterLabs platform. Prefer alternatives if you need high-frequency tick data, streaming rates, or guaranteed SLA uptime.
