SentiSignalFX Rate API
Forex product API

FX Rate API for spot and historical currency pairs

Query current exchange rates, pull daily historical series with summary stats, and rely on EUR-chain fallback for missing direct pairs.

Daily ECB reference rates • Paid historical access • Shared key across all market-data products

Why teams use the FX API

Spot + historical rates

Query live pairs or historical series with daily, weekly, monthly, and yearly buckets. FX data is daily ECB reference-rate data.

EUR cross-rate fallback

Pairs missing a direct quote are resolved through the EUR chain instead of failing fast.

Shared product tier

The same API key covers gold, FX, commodity, and MCP access under one plan model.

Developer-safe responses

Predictable JSON payloads with summary statistics for historical endpoints and typed validation on input.

FAQ

Which pairs are supported?

The API serves tracked currencies stored in `fx_rates`, with direct and EUR-derived cross rates where available.

Is historical access free?

No. The free plan is intended for spot lookups. Historical endpoints require a paid tier.

Does it support yearly data?

Yes. Historical requests accept `daily`, `weekly`, `monthly`, and `yearly` intervals.

Is it real-time forex?

No. Current FX coverage comes from daily Frankfurter/ECB reference rates, not intraday trading feeds.
