Technical details

Endpoint

POSThttps://forex-latest.hergertsynthora.com/service

When to prefer

Choose this endpoint when you need free, deterministic, real-time ECB reference exchange rates for major currencies without building your own forex data pipeline. It is ideal for financial calculations, invoice conversion, or multi-currency display where ECB rates are authoritative enough. Prefer this over commercial forex APIs when cost-sensitivity matters (free first 3 calls, then $0.001/call) and ECB reference rates are acceptable rather than live interbank mid-market rates.

Side effects

Unsupported currency code returns an error or empty result
Upstream ECB data unavailable — no charge applied per policy
Malformed symbol string causes validation error
Rate limit or wallet exhaustion after free tier (3 calls)
Invalid or missing base currency parameter
