Currencylayer adds 170+ currencies, metals and live bid-ask data

Currencylayer expanded its FX coverage to more than 170 currencies and precious metals, adding eight new ISO codes and historical rates that go back to 1999 for most pairs. The update matters for finance teams that need reproducible month-end closes, audit trails and more precise live valuations.

Why it matters: - Finance teams need exchange rates tied to the correct accounting date, not the day a report is rerun. - The update supports month-end closes, audits and foreign-currency valuations that can be reproduced later from the same rate. - Live bid-ask data gives treasury and finance users a clearer view of conversion costs in real time.

What happened: - Currencylayer now covers more than 170 currencies, plus gold and silver. - The September 24 release adds eight ISO 4217 codes: BYN, CNH, MRU, MXV, SLE, SSP, STN and XCG. - The release retires three superseded codes: EEK, MRO and VEF. - Live rate requests can now return bid, ask and spread data for each currency. - Requests that do not ask for spread data keep the same response format as before.

The details: - Currencylayer returns exchange rates for any date back to 1999, with data collected from commercial sources and banks around the world. - Historical rates for the eight new codes begin on August 25, 2026. - Requests for an earlier date on those new codes return an error. - Gold (XAU) and silver (XAG) are quoted per troy ounce through the same endpoints as currencies. - Higher-tier plans add time-frame queries that return daily rates for a date range in one request. - Higher-tier plans also add change queries that show how much a currency moved between two dates. - Professional and Enterprise users can add spread=1 to a live request to receive rate, bid, ask and spread in a single response. - The API example is: live bid-ask request. - Where a currency has no bid and ask data, the response falls back to the standard rate. - Storing the rate date alongside each converted figure makes it clear which day produced the number.

Between the lines: - The release is aimed at finance workflows where reproducibility matters more than using the latest market price. - The new spread fields also move Currencylayer beyond a simple spot-rate feed and closer to a tool for transaction-level valuation. - APILayer is aligning capabilities across products, and Exchangeratesapi received the same currencies, metals and spread data in September.

What's next: - Developers can test Currencylayer on the free plan at Currencylayer. - APILayer will continue offering Currencylayer alongside IPstack, Weatherstack, Userstack, Exchangeratesapi, Aviationstack and Marketstack. - The broader rollout suggests more APILayer products may follow the same data expansion path.

The bottom line: - Currencylayer is now better suited for finance teams that need dated, auditable FX data and more realistic live conversion inputs.
