Returns an object containing current exchange rate data for the requested currency pair, including the rate value and potentially metadata such as timestamp and currency codes.
Example use cases

“I need to send an invoice for 2500 USD to a client in Germany — what's the current USD to EUR exchange rate and what would that amount be in euros?”
Travel budget planning
“I'm budgeting for a trip to Japan — can you tell me the current USD to JPY exchange rate so I can figure out how much yen I'll need for a $3000 budget?”
Crypto or stock portfolio valuation
“My portfolio is tracked in GBP but I need to report its value in USD for US taxes — what's the current GBP to USD exchange rate?”
Technical details
Endpoint
POSThttps://coockies-ai.vercel.app/api/exchangerate-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call exchange rate lookup without committing to a monthly subscription to ExchangeRate-API directly. It is well-suited for low-frequency or sporadic currency conversion needs in automated agent workflows where cost should scale with usage rather than being a fixed overhead.
Side effects
- Unsupported or invalid currency code returns an error or empty result
- Network timeout if the upstream ExchangeRate-API is unavailable
- Stale rate data if the upstream provider hasn't refreshed recently
- Payment failure on Base chain if USDC balance is insufficient for the $0.057068 per-call fee
- Malformed input schema may return a generic error response
