Central Board of Indirect Taxes and Customs (CBIC) Exchange Rates API — cbic-exchange-rate

Official Central Board of Indirect Taxes and Customs (CBIC) (India) fortnightly exchange rates for Node.js and TypeScript. The published tax authority rates behind tax filings, customs valuations, audits, and compliant invoicing — not market estimates, but the numbers Central Board of Indirect Taxes and Customs (CBIC) itself prints, about every fortnight.

🚀 Why this client?

• 🏛️ Official rates — Central Board of Indirect Taxes and Customs (CBIC)'s own table, with the publisher's own rate_date on every response
• 📅 History back to 2020 — point-in-time tables and daily series for any past date
• 🔀 Official vs derived, always flagged — computed inverse/cross pairs carry derived: true, never mixed with official prints
• ⚡ Zero dependencies — pure ESM + CJS over global fetch; Node 18+, Bun, Deno, and edge runtimes
• 🔷 Type-safe — full TypeScript definitions shipped with the package
• 🧾 Compliance-grade metadata — rate_type, publication date, and source disclaimer on every response

Official rate, not mid-market: every value here is a number Central Board of Indirect Taxes and Customs (CBIC) itself published, fixed once printed and carrying the tax authority's own rate_date — what filings and audits require. Need the live mid-market rate for pricing or display instead? Use the mid-market API or @allratestoday/sdk. The two can diverge by several percent.

📈 Latest official table

The image is rendered live from the keyless endpoint, so it follows the tax authority's publications on npm and on GitHub alike without a new release. The same table as text is folded below for search and copy-paste: on GitHub a daily Action refreshes it whenever the tax authority publishes a new table; on npm it is as of the package's publish date.

Table for a date

Paid plans. The official table for any date since 2020 — weekends and holidays return the most recent published date, flagged via published_on_requested_date, which is exactly the in-force rate a filing needs.

import { getRatesForDate } from 'cbic-exchange-rate';

const day = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...' });
// Optionally narrow to one pair:
const one = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...', source: 'USD', target: 'INR' });

Response:

{
  bank: 'cbic',
  requested_date: '2026-06-30',
  rate_date: '2026-06-30',                // the date actually published
  published_on_requested_date: true,      // false when a weekend/holiday fell back
  rates: [ /* the full table for that date */ ],
  disclaimer: '…'
}

Daily time series

Paid plans. One resolved rate per publication date — ready for charting, revaluation runs, or audit workpapers.

import { getHistory } from 'cbic-exchange-rate';

const series = await getHistory(
  { source: 'USD', target: 'INR', from: '2026-01-01', to: '2026-11-06' },
  { apiKey: 'art_live_...' }
);

Response:

  bank: 'cbic',
  source: 'USD',
  target: 'INR',
  from: '2026-01-01',
  to: '2026-11-06',
  count: 152,
  rates: [
    // one entry per publication date
    { date: '2026-11-06', rate: 93.65, rate_type: 'export', derived: false, method: 'published' },
    // …
  ],
  disclaimer: '…'
}

Pass { symbol: 'USD' } instead of source/target to get the raw published rows for one currency (all rate types, no pair resolution).

🗺️ Currencies covered

Central Board of Indirect Taxes and Customs (CBIC) currently publishes rates covering 22 currencies against the INR (as of the latest table):

🇦🇪 AED · 🇦🇺 AUD · 🇧🇭 BHD · 🇨🇦 CAD · 🇨🇭 CHF · 🇨🇳 CNY · 🇩🇰 DKK · 🇪🇺 EUR · 🇬🇧 GBP · 🇭🇰 HKD · 🇯🇵 JPY · 🇰🇷 KRW · 🇰🇼 KWD · 🇳🇴 NOK · 🇳🇿 NZD · 🇶🇦 QAR · 🇸🇦 SAR · 🇸🇪 SEK · 🇸🇬 SGD · 🇹🇷 TRY · 🇺🇸 USD · 🇿🇦 ZAR

🏛️ Source

The Central Board of Indirect Taxes and Customs (CBIC) notifies the customs exchange rates for India under Section 14 of the Customs Act, 1962 — the rates at which the value of imported and exported goods is converted into rupees on a Bill of Entry or Shipping Bill, and the rates GST valuation rules borrow for imports. A notification is issued roughly every fortnight, takes effect the following day, and carries two rates per currency: one for imported goods and one for exported goods. They are set off State Bank of India card rates, so they sit a few percent either side of the Reserve Bank of India's reference rate by design.

• Publisher's own page: Exchange rate notifications (ICEGATE) · www.cbic.gov.in
• Publication: about every fortnight; the exact schedule, freshness status and any current delay are on the Central Board of Indirect Taxes and Customs (CBIC) rates page
• Values are stored unmodified, with the publisher's own rate_date on every row — see the methodology

🧭 Reading the numbers

• value is always quote currency per 1 unit of base currency (base: "EUR", quote: "USD", value: 1.15 means 1 EUR = 1.15 USD).
• Central Board of Indirect Taxes and Customs (CBIC) quotes INR per 1 unit of foreign currency (e.g. base: "USD", quote: "INR" means INR per one US dollar).
• Need the other way round? Ask getRate(target, source) and the API inverts or crosses for you, flagged derived: true — never divide a published rate yourself in a compliance workflow.
• rate_type tells you which of the tax authority's series a row belongs to (export here); some publishers print buy/sell or several fixings for the same pair.

🧩 ERP & accounting systems

Loading the official Central Board of Indirect Taxes and Customs (CBIC) rate into an accounting system is a supported workflow, not a hack. Step-by-step guides with the direction each system expects:

• Dynamics 365 Business Central — built-in Currency Exchange Rate Service, no code
• Xero · QuickBooks Online · SAP S/4HANA and ECC · Odoo

The same keyed endpoints return ?format=csv, ?format=xml and ?format=xlsx, and accept the key as ?api_key= on the URL for importers that cannot send headers:

curl "https://allratestoday.com/api/v1/central-bank/cbic/latest?format=xml&api_key=art_live_..."

🤖 AI agents

• MCP server: npx -y @allratestoday/central-bank-mcp (stdio) or the hosted endpoint https://allratestoday.com/api/mcp — tools for official rates, history, cross-bank comparison and publication calendars
• Already using the general SDK or MCP server? Since 2026-10-01 @allratestoday/sdk 1.4+ has officialRates('cbic') and @allratestoday/mcp-server 0.6+ has a get_official_rates tool — both return this source's latest table with no key, so you can add it without a second dependency
• Claude Code plugin (no key): /plugin marketplace add AllRates-Today/claude-code-plugin then /plugin install allratestoday@allratestoday — bundles both MCP servers plus an /official-rate cbic ... command
• Evaluating? Agents can self-issue a trial key with no signup: POST https://allratestoday.com/api/agent/keys (send Content-Type: application/json) returns a 100-call key valid 7 days that covers the free-plan methods (latest table, pairs); dated tables and history need a paid plan. The MCP servers expose it as request_trial_key

⚖️ Official vs derived rates

If Central Board of Indirect Taxes and Customs (CBIC) does not print a pair directly, the API resolves it from the tax authority's own table and says so — official and computed values are never confused:

| method | derived | Meaning | | --- | --- | --- | | published | false | The tax authority printed this pair directly | | inverse | true | Computed as 1 ÷ the published opposite direction | | cross | true | Computed via INR from two published rates |

🛡️ Error handling

Errors are thrown as Error with status (HTTP code) and body (the API's JSON error) attached:

try {
  const pair = await getRate('USD', 'XXX', { apiKey: 'art_live_...' });
} catch (err) {
  console.log(err.message); // human-readable reason
  console.log(err.status);  // e.g. 404
}

| Status | Meaning | | ------ | ------- | | — | Missing apiKey (thrown before any request) | | 400 | Malformed date or parameters | | 401 | Invalid API key | | 403 | Endpoint needs a paid plan (historical dates & series) | | 404 | Pair or date range not covered by Central Board of Indirect Taxes and Customs (CBIC) | | 429 | Monthly quota exceeded |

🔷 TypeScript

Full definitions ship with the package — no @types install:

import type { LatestRates, PairRate, DatedRates, RateEntry, HistoryQuery, RequestOptions } from 'cbic-exchange-rate';

📦 CommonJS

const { getRate } = require('cbic-exchange-rate');

getRate('USD', 'INR', { apiKey: 'art_live_...' }).then((pair) => console.log(pair.rate));

💡 Quota tips

• Rates change about once a fortnight — cache the official table locally and a small monthly quota goes a long way.
• Every request counts toward your AllRatesToday quota, shared across all AllRatesToday endpoints on your key.
