Bangko Sentral ng Pilipinas Exchange Rate API: Official PHP Rates as JSON

The Bangko Sentral ng Pilipinas publishes the official exchange rates that accounting, tax, and customs rules in the Philippines reference — published official rates, not moving market prices. This guide shows how to pull them as JSON: via a REST endpoint or the zero-dependency bsp-exchange-rate npm package.

What the BSP publishes

• ~30 currencies against the peso — the full Reference Exchange Rate Bulletin, published each banking morning.
• The bank's own publication date on every response, so a rate is always citable.
• No gaps to trip over — requests for weekends and Philippine holidays resolve to the most recent published bulletin and are flagged explicitly.

The USD/PHP reference rate anchors the bulletin: it is the rate Philippine banks, customs brokers, and the BIR reference for peso conversion.

Why official rates, not market rates

A live mid-market feed answers "what is USD/PHP trading at right now?" — the right tool for checkouts and dashboards. But accountants, auditors, and tax authorities ask a different question: "which rate were you required to use for this date?" That answer comes from the Bangko Sentral ng Pilipinas's published rates, and it never changes after publication.

Get the latest rates (REST)

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

The response is the bank's most recent published data — every rate and the publication date. The latest rates are available on every plan, including the free tier (300 requests/month, no credit card).

The npm SDK

npm install bsp-exchange-rate

import { getRate, getLatestRates } from 'bsp-exchange-rate';

// One pair at the official BSP rate
const pair = await getRate('USD', 'PHP', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

// The bank's full published table
const table = await getLatestRates({ apiKey: 'art_live_...' });
console.log(table.rate_date, table.rates.length);

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

Historical rates for an invoice date

import { getRatesForDate, getHistory } from 'bsp-exchange-rate';

// The official rates for an invoice date — non-publication days return
// the most recent published date, flagged via published_on_requested_date.
const day = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...' });

// Time series for one pair
const series = await getHistory(
  { source: 'USD', target: 'PHP', from: '2026-01-01' },
  { apiKey: 'art_live_...' }
);

Historical dates and time series need a paid plan; the latest rates stay free.

Published vs derived pairs

If the BSP does not print a pair directly, the API resolves it from the bank's published rates — an inverse, or a cross rate via PHP — and flags it derived: true with the method used. Official and computed values are never silently mixed, which is exactly the distinction an auditor will ask about.

A series that grows every day

AllRatesToday began archiving the BSP bulletin in August 2026, and every business day adds another citable table. For invoice-date lookups inside that window, the official record is one API call away — and the window only gets deeper.

FAQ

Does the Bangko Sentral ng Pilipinas have an official exchange rate API?

The BSP publishes its official rates on its own site, and AllRatesToday serves the same published rates as clean JSON via REST or the bsp-exchange-rate npm package. The latest table is free.

How often do Bangko Sentral ng Pilipinas rates update?

Every banking morning, Manila time. The bulletin is a published reference table, not a moving market price — every API response carries the publication date so you can cite it.

Can I get the BSP rate for a past date, like an invoice date?

Yes. The /central-bank/bsp/rates-for-date endpoint returns the official rates for any archived date. Non-publication days resolve to the most recent published date and are flagged, so your audit trail stays honest. Historical dates require a paid plan; latest rates are free.
