How this service works
MARKETS: daily FX time series between two dates for one pair (?start=2024-01-01&end=2024-02-01&base=USD&symbol=EUR). Returns JSON.
Output
A JSON object containing daily exchange rate values for the requested currency pair (e.g. USD/EUR) across each day in the specified date range, indexed by date.
Example use cases
Calculate average costs for international payroll
“I need to figure out what we actually paid in USD equivalent for our GBP salaries last quarter. Can you pull the daily GBP to USD rates from October through December 2023 so I can calculate the average conversion cost?”
Analyze currency volatility for risk management
“We're planning a major purchase in Swiss francs next month and want to understand how volatile CHF has been lately. Can you get me the daily USD to CHF exchange rates for the last three months so we can assess our exposure?”
Audit historical foreign revenue reporting
“Our accounting team needs to verify the exchange rates we used to report revenue from our Japan office last year. Can you pull the daily JPY to USD rates for all of 2023 so we can reconcile our conversion numbers?”
Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/fx-timeseriesWhen to prefer
Use this endpoint when you need a historical daily FX time series for a specific currency pair over a defined date range, especially for financial analysis, charting, or reporting. Prefer this over spot-rate or live-rate endpoints when historical data spanning multiple days is needed. Ideal for agents building forex dashboards, backtesting currency strategies, or calculating average rates over a period.
Side effects
- Invalid date format — start or end date not in YYYY-MM-DD format returns an error
- Unsupported currency code — unrecognized base or symbol currency returns an error
- Date range too wide or reversed (start after end) may return empty or error response
- Network or payment failure — x402 payment of $0.02 USDC not processed results in 402 response
- Missing required parameters — omitting start, end, base, or symbol returns a bad request error
