How this service works
Supported currencies.
Output
Returns a paginated list of currency objects supported by the Marketstack platform, each including currency code, name, and related metadata. The response is scoped by an optional limit parameter controlling how many records are returned.
Example use cases
Validate currency before price lookup
“Before I query stock prices, can you check what currencies Marketstack supports so I know which ones I can use for denomination?”
Build currency selector dropdown
“I'm building a financial dashboard — can you fetch all the currency codes Marketstack supports so I can populate a currency selector for users?”
Audit supported currency coverage
“Can you get me the first 20 currencies that Marketstack supports? I want to see if EUR, GBP, and JPY are all in there.”
Technical details
Endpoint
GEThttps://gateway.apiosk.com/marketstack/currenciesWhen to prefer
Use this endpoint when you need to enumerate or validate the set of currencies available within the Marketstack ecosystem before making downstream stock price or exchange rate queries. Prefer this over manual currency lists when you need a canonical, up-to-date set of Marketstack-supported currencies. It is a lightweight, read-only lookup with no side effects, making it safe to call frequently for reference data.
Side effects
- Invalid limit parameter type returns a 400 validation error
- Payment not processed (402) if x402 USDC payment is not attached or insufficient
- Rate limiting or quota exceeded returns a 429 or 402 response
- Gateway timeout if upstream Marketstack API is unavailable
- Empty result set if no currencies are indexed
