What people say

CTO, Fuze Finance

One of the bedrocks of Fuze is good financial data and TraderMade is tailor made for our use-case. The flexibility of the API to fetch prices for different FX pairs, the robustness and availability of the API has never failed us.

Srijan Shetty
CTO, Fuze Finance
COO, BITA Data

TraderMade has been a reliable source of FX and Precious Metals pricing data. In the indexing industry, you have to be as precise as a Swiss watch. Using TraderMade has been a help for Bita to reach that precision on our calculations.

Frequently asked questions

You can convert currencies in two ways, depending on your application's architecture.

On-demand (/convert): pass from, to, and amount to receive an instant, pre-calculated conversion total.

Batch caching (/live): request live mid-market, bid, and ask rates for single or multiple pairs in one call, then cache them locally (e.g. Redis) and calculate conversions on your own backend with zero added API latency.

/convert is an ad-hoc calculation utility for simple lookups, internal reporting, or quick prototypes where you need a single total for a specific amount.

/live is engineered for production checkouts, payment service providers (PSPs), and high-volume billing. Query multiple pairs at once (currency=EURUSD,GBPUSD,USDJPY), get dual-sided bid/ask prices to apply custom spread markups, and run millions of user-facing conversions without incurring an API credit on every page view.

Unlike budget APIs that scrape delayed daily fixings from central banks (such as the European Central Bank), TraderMade aggregates live pricing directly from Tier-1 banks and institutional non-bank liquidity providers. This ensures continuous, unbiased interbank pricing with real-time bid, ask, and mid-market rates.

Yes. The API provides real-time bid/ask prices alongside mid-market rates, allowing cross-border payment platforms, remittance providers, and e-commerce checkouts to dynamically set localized customer pricing while preserving profit margins against currency volatility.

TraderMade supports over 4,000 currency pairs covering more than 70 liquid fiat currencies (including all G10 and major emerging-market corridors), spot precious metals (Gold, Silver, Platinum, Palladium), and major cryptocurrencies. Direct cross-rates are calculated automatically, so there is no need to manually triangulate crosses through USD.

The 7-day trial provides full sandbox and production access to the /convert and /live endpoints, 4,000+ pairs, and historical rate snapshots. We require a verified business email to prevent automated scraping, protect latency for active production clients, and provide direct technical onboarding to engineering and finance teams.
