Quickstart

Use the API directly from browsers, scripts, build jobs, or AI agents. No SDK is required; every endpoint returns predictable JSON.

curl "https://api.bitsark.com/v1/exchanges?accepts_pix=true&brazil_registered=true"

const res = await fetch('https://api.bitsark.com/v1/exchanges/mercado-bitcoin');
if (!res.ok) throw new Error('BitsARK API ' + res.status);

const body = await res.json();
console.log(body.data.fiscal_details_br.tax_regime);

import json
from urllib.request import urlopen

with urlopen("https://api.bitsark.com/v1/exchanges/mercado-bitcoin") as res:
    body = json.load(res)

print(body["data"]["fiscal_details_br"]["tax_regime"])

Schema reference

Complete field reference for the full exchange object returned by /v1/exchanges and /v1/exchanges/:id. The fiscal_details_br section is particularly relevant for tax compliance and portfolio tooling.

Query filters

The following query parameters are supported by /v1/exchanges and /v1/exchanges/fees. Filters can be combined freely.

Combined example: Brazilian-registered, BCB-authorized exchanges that accept Pix:

curl "https://api.bitsark.com/v1/exchanges?brazil_registered=true&bcb_licensed=true&accepts_pix=true"

tax_regime values

The fiscal_details_br.tax_regime field defines the exchange's Brazilian tax classification. This determines reporting obligations for both the exchange and its users.

exchange_rfb_reports

The fiscal_details_br.exchange_rfb_reports array lists automatic reporting obligations that the exchange fulfills with Brazil's Receita Federal (RFB) on behalf of its users.

user_rfb_action_monthly

The fiscal_details_br.user_rfb_action_monthly array lists monthly obligations the user must fulfill - actions not covered by the exchange automatic reporting.

main_jurisdiction_iso

The operational_details_br.main_jurisdiction_iso field uses ISO 3166-1 alpha-2 to identify the exchange's primary legal jurisdiction. You can convert it to a flag emoji with:

const toFlag = (iso) => String.fromCodePoint(...[...iso].map(c => 0x1F1E6 - 65 + c.charCodeAt(0)));

BR → 🇧🇷   SC → 🇸🇨   KY → 🇰🇾   VG → 🇻🇬

Fees & spread model

Exchanges integrated into financial apps (e.g. Nubank Cripto, Mercado Pago, Mynt, Bipa) typically use a spread-based or flat-rate model instead of traditional maker/taker fees. In these cases the response may return:

"maker": null, "taker": 0.006 // spread/flat-rate model

Rendering guide for frontends:

When maker is null and taker has a value, treat it as the nominal flat rate and label it accordingly in your UI.
