DXtrade API GET /conversionRates
Read the current conversion rate between two currencies, or from every currency to one.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
Read on 12 Oct 2026 in the DXtrade REST API specification on DXtrade's developer portal. The portal draws its pages in the browser from Markdown files it also serves directly, and the Markdown file of this page (DXtrade-REST-API.md) is what was read, with the model files it includes. The portal writes each address after a base address it fills in from its own settings, which on this portal is https://demo.dx.trade/dxsca-web. A broker or firm that offers DXtrade hosts its own, so the path here is what follows that base. The specification says every request needs authentication unless it says otherwise, and this section says the Authorization header should be included, which is why it is recorded as required. The method is recorded as GET: the page shows its GET badge beside this address and describes an empty request with query parameters, although the badge's alternative text in the Markdown reads POST. The reply is a list of conversion rates, each with fromCurrency, toCurrency and convRate, all three marked required.
Parameters
| Name | In | Type | Description |
|---|---|---|---|
| toCurrencyrequired | query | string | The target currency. Marked required. |
| fromCurrency | query | string | Marked optional. The source currency. Without it the rates from every currency to toCurrency are returned. |
Authentication headers
| Name | Type | Description |
|---|---|---|
| Authorizationrequired | string | With token authentication, send DXAPI followed by the sessionToken from POST /login. With HMAC authentication the same header carries DXAPI with a principal, a timestamp and a hash, signed for each request as the specification describes. Placeholder only: never paste a real token into this site. |
Request
Written from the method, path and parameters recorded on this page. No demo host is recorded as a plain address for this API, so the samples read the base address from an environment variable. Not executed against a live or demo account. Credentials are read from environment variables on your own machine and are never entered on this site. The request builder writes these same snippets, from the same record.

# No demo host is recorded as a plain address for this API, so the base address is read from DXTRADE_BASE_URL.
# Replace each {placeholder}, "..." and 0 with a real value before running.
# Optional and not shown: query parameters fromCurrency.

No mock response is recorded for this endpoint. Where the record says why, or names the fields of the reply, it does so in the note at the top of this page. That is a statement about this record, not about what the API returns: read the shape of the reply in the official reference.
