Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/bank-of-england-iadb?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official, authoritative historical exchange rate or macroeconomic time-series data directly from the Bank of England IADB, without requiring an API key or account signup. Ideal for AI agents needing pay-per-call access to UK central bank data for forex analysis, monetary policy research, or financial reporting. Prefer this over general forex APIs when the Bank of England is explicitly the required source.
Side effects
- Invalid or unknown series code returns empty rows or an error
- Days parameter out of range (outside 1-365) may return a validation error
- Bank of England IADB source unavailable results in fetch failure
- No data available for the requested date range (e.g. weekends/holidays with no published values)
- Payment failure (insufficient USDC balance) results in HTTP 402 with no charge
