Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — bank-of-thailand-exchange-rate:

npm install bank-of-thailand-exchange-rate

import { getRate } from 'bank-of-thailand-exchange-rate';

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

Zero dependencies, TypeScript types included, and it runs anywhere fetch exists — Node 18+, Bun, Deno, and edge runtimes.

Full reference — installation, all four functions, response shapes, error codes: bank-of-thailand-exchange-rate documentation.

Why use the official Bank of Thailand rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in Thailand and beyond typically require the official rate published by Bank of Thailand 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.

If a pair isn't in the bank's published table, the API computes it from that table (inverse or cross via THB) and marks it "derived": true — published and computed values are never silently mixed.

Endpoints

• GET /api/v1/central-bank/bot/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/bot/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/bot/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/bot/availability — publication calendar: the dates the bank actually published (all 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 published table locally makes a small quota go far.

Frequently asked questions

Can I get Bank of Thailand exchange rates via an API?

Yes — this API serves the bank's official daily THB rates as JSON, and the latest table is on every plan, free included.

When do new rates appear here?

Once per business day, per Bank of Thailand's own schedule; ingestion follows within the hour (latest table: 2026-09-15).

Are these the official rates?

Yes — ingested from Bank of Thailand's own published data, served unmodified with the bank's publication date. Anything computed rather than published is flagged derived.
