How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with ok and paid status flags, along with historical foreign exchange rate data for the requested currency pair and date, enabling currency conversion calculations and financial record-keeping.

Example use cases

Accounting currency reconciliation

“What was the GBP to USD exchange rate on January 31, 2024? I need the historical rate to reconcile our quarterly accounts in both currencies.”

Travel expense reimbursement calculation

“Look up the JPY to USD exchange rate for November 10, 2023 — I need to calculate what our team's Tokyo expenses were worth in dollars for the expense report.”

Investment portfolio historical valuation

“What was the EUR to CHF rate on June 1, 2023? I'm trying to value a European portfolio position in Swiss francs at that point in time.”

When to prefer

Choose this endpoint when you need historical (past-date) FX rates for financial calculations, accounting, or analysis and want to pay per call without API key registration. Ideal for AI agents operating autonomously with USDC micropayments on Base. Prefer alternatives if you need real-time live rates, high-volume batch historical data, or regulatory-grade financial data sources.

Invalid or unsupported currency pair returns an error response
Date out of available historical range returns no data or error
Malformed schema parameter causes request failure
Payment failure via x402 protocol results in 402 response blocking data access
Missing required parameters may return empty or error response
