Best Exchange Rate API for the UAE in 2026: 8 Compared for AED Rates, Central Bank and Bank Rates

The dirham is pegged to the dollar, which makes UAE currency work look simple until the first euro invoice. Then the questions start: which rate goes on the tax invoice, what the e-invoice needs from 2027, and how far your bank's rate is from the Central Bank's. The UAE is also the country where the choice of API matters most, because the Central Bank of the UAE table is missing from almost every provider.

This comparison looks at eight exchange rate APIs from the point of view of a team in the UAE. Free-tier limits and prices were read from each provider's own pricing page on 10 November 2026; they change often, so confirm before you commit.

What a team in the UAE needs from an exchange rate API

• Live AED pairs for pricing, remittance and trade.
• The Central Bank of the UAE table, which Article 69 of the VAT Decree-Law names for foreign-currency tax invoices and Article 43 of the Corporate Tax Law names for the return.
• The rate by date, because the VAT rule is the rate at the date of supply.
• A feed your ERP can load: the exchange rate is a mandatory e-invoice field for non-AED invoices from 2027.
• UAE bank boards to see what a payment will actually cost.

Quick comparison

The UAE rates and what they are for

• Central Bank of the UAE rates. A daily table of more than 70 currencies against the dirham, updated Monday to Friday, which the bank publishes for VAT-related obligations.
• VAT, Article 69. A supply in another currency is converted for the tax invoice at the exchange rate approved by the Central Bank at the date of supply, and the invoice must show the rate applied.
• Corporate tax, Article 43. Amounts in another currency are converted at the applicable Central Bank rate. FTA Decision No. 13 of 2023 sets the order: spot rate, then monthly average, then annual average.
• E-invoicing. Mandatory from 1 January 2027 for businesses with revenue of AED 50 million or more, and from 1 July 2027 below that. The exchange rate is a required field when the invoice currency is not AED.

The point for choosing an API: a market mid-rate and an official table are different products. A market rate is right for showing a customer a price. It is not the figure a tax form or an auditor asks for.

The eight providers

1. AllRatesToday

Best for: teams that need both kinds of rate. Mid-market rates for 160+ currencies refresh every 60 seconds on every plan, on any base currency, over HTTPS. The same key serves the official tables of 123 central banks and 6 tax authorities, each with the publisher's own date. For the UAE that means: Central Bank of the UAE table (75 currencies) and five UAE bank boards. Output is JSON, CSV, XML or Excel from the same endpoints, with SDKs for JavaScript, Python, PHP, Go and Rust and an MCP server for AI agents. Paid plans start at €4.99 a month; dated tables and history are on paid plans.

2. Frankfurter

Best for: projects that only need official fixings and want them free. Frankfurter is open source, needs no key and has no monthly cap. It now aggregates 111 central banks and official sources. Check its source list for your country before you build on it: on 10 November 2026 it did not include the Central Bank of the UAE. It serves official fixings, not a live market rate, and it is a free service with no paid tier or support contract.
