How this service works
Agent data gateway plus the live x402 market feed. Normalized, schema-stable JSON for crypto prices, DeFi TVL, on-chain DEX pools, gas, FX, US Treasury yields, US weather, WHOIS, DNS, email validation, web-page extraction, tech news, Wikipedia, npm/PyPI package health, ERC-20 token-risk scoring, and composed domain dossiers, plus x402 ecosystem analytics and metered LLM inference. Pay per call with USDC via the x402 protocol; no accounts, no API keys.
Output
A JSON object with ok:true, a data object containing the base currency, quote currency, exchange rate (float), and the date of the rate, plus a meta object with cache status, source name (e.g. 'frankfurter (ECB)'), and the timestamp the rate was fetched.
Example use cases
Travel budget currency conversion
“I'm heading to Japan next week — what's the current USD to JPY exchange rate so I can figure out how much yen to bring?”
Invoice pricing in foreign currency
“I need to quote a client in euros but my prices are in USD — what's today's USD to EUR rate from the ECB?”
Cross-currency portfolio valuation
“What's the live GBP to CHF exchange rate right now? I need it to calculate the current value of my UK holdings in Swiss francs.”
Technical details
Endpoint
GEThttps://gateway.stride20k.com/fx/%7Bbase%7D/%7Bquote%7DWhen to prefer
Choose this endpoint when you need normalized, schema-stable FX rates backed by ECB data, with no account setup — just pay $0.002 USDC per call via x402. Ideal for agents that need reliable, consistently formatted currency data without managing API keys or subscriptions. Prefer over raw Frankfurter API when you want a single unified gateway that also covers crypto, gas, and other financial data types.
Side effects
- Unsupported or invalid currency code returns an error response
- ECB-sourced rates may be delayed by one business day (not truly real-time intraday)
- Rate may be cached; the 'cached' flag in meta indicates staleness
- Currencies not covered by the ECB/Frankfurter dataset will not be available
- Payment failure via x402 will block access before the data is returned
