Quick start

One request for the pair you need — GBP to USD at the official Bank of England rate:

curl "https://allratestoday.com/api/v1/central-bank/boe/latest?source=GBP&target=USD" \
  -H "Authorization: Bearer art_live_your_key"

Or the bank's full published table:

curl "https://allratestoday.com/api/v1/central-bank/boe/latest" \
  -H "Authorization: Bearer art_live_your_key"

On paid plans, any historical date or a daily time series:

curl "https://allratestoday.com/api/v1/central-bank/boe/history?source=GBP&target=USD&from=2025-01-01" \
  -H "Authorization: Bearer art_live_your_key"

Latest published rates (2026-07-30)

Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — boe-exchange-rate:

npm install boe-exchange-rate

import { getRate } from 'boe-exchange-rate';

const pair = await getRate('GBP', 'USD', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

Why use the official Bank of England rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in United Kingdom and beyond typically require the official rate published by Bank of England for a given date — a fixed, citable number that never changes after publication. This API serves those published tables with the bank's own rate_date on every response; weekends and holidays return the most recent published date, which is the rate compliance rules require you to apply.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via GBP) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/boe/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/boe/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/boe/history — daily time series, up to 5,000 rows (paid plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a day's table locally makes a small quota go far.
