Available APIs

1. get_capabilities

Query supported fiat currencies, cryptos, and business types for a country.

curl "https://www.binance.com/bapi/fiat/v1/public/fiatpayment/agent/get-capabilities?country={COUNTRY_CODE}"

Optional: businessType (BUY, SELL, DEPOSIT, WITHDRAW) to filter.

Response: data.supportedBusinessTypes, data.fiatCurrencies[] (with code, name, supportedBusinessTypes), data.cryptoCurrencies[]

2. get_buy_and_sell_payment_methods

curl "https://www.binance.com/bapi/fiat/v1/public/fiatpayment/agent/get-buy-and-sell-payment-methods?businessType={BUY|SELL}&fiatCurrency={FIAT}&cryptoCurrency={CRYPTO}&country={COUNTRY_CODE}"

All 4 parameters required.

Response: data.paymentMethods[] and data.p2pPaymentMethods[], each with code, paymentMethodName, fiatMinLimit, fiatMaxLimit, cryptoMinLimit, cryptoMaxLimit, quotation, suspended

3. get_deposit_and_withdraw_payment_methods

curl "https://www.binance.com/bapi/fiat/v1/public/fiatpayment/agent/get-deposit-and-withdraw-payment-methods?businessType={DEPOSIT|WITHDRAW}&fiatCurrency={FIAT}&country={COUNTRY_CODE}"

All 3 parameters required. No cryptoCurrency, no quotation, no P2P methods.

Response: data.paymentMethods[] with code, paymentMethodName, fiatMinLimit, fiatMaxLimit, suspended

4. get_price

curl "https://www.binance.com/bapi/fiat/v1/public/fiatpayment/agent/get-price?fiatCurrency={FIAT}&cryptoCurrency={CRYPTO}&country={COUNTRY_CODE}"

Optional: businessType (BUY or SELL, defaults to BUY).

Response: data.bestPrice — indicative reference price, may differ from execution price

Recommended Workflow

1. get_capabilities first — confirms what's supported before making other calls
2. Payment methods API — BUY/SELL → get_buy_and_sell_payment_methods; DEPOSIT/WITHDRAW → get_deposit_and_withdraw_payment_methods
3. get_price — add if the user wants exchange rate info

Skip step 1 for simple price queries (e.g., "What's BTC in USD?").

Calling APIs

Use WebFetch or Bash (curl). All responses follow:

{ "code": "000000", "message": null, "data": { ... }, "success": true }

code: "000000" = success; otherwise check message.

Action Links

After presenting API results, always include a relevant action link so the user can proceed directly on Binance. Build the URL dynamically based on the fiat currency, crypto currency, and business type from the conversation context.

URL Templates

Business Type	URL Template	Example
BUY	https://www.binance.com/en/crypto/buy/{FIAT}/{CRYPTO}	Buy BTC with USD
SELL	https://www.binance.com/en/crypto/sell/{FIAT}/{CRYPTO}	Sell BTC for USD
DEPOSIT	https://www.binance.com/en/fiat/deposit/{FIAT}	Deposit USD
WITHDRAW	https://www.binance.com/en/fiat/withdraw/{FIAT}	Withdraw USD

Language-aware URL

Replace the /en/ locale segment to match the user's language. Supported locales:

en, zh-CN, zh-TC, ru, es, es-LA, fr, vi, en-TR, it, pl, id, uk-UA, ar,
en-AU, pt-BR, en-IN, en-NG, ro, bg, cs, lv, sv, pt, es-MX, el, sk, sl,
es-AR, fr-AF, en-KZ, en-ZA, en-NZ, en-BH, ar-BH, ru-UA, de, kk-KZ,
ru-KZ, ja, da-DK, en-AE, en-JP, hu, lo-LA, si-LK, az-AZ, uz-UZ, pt-AO

Common mapping examples:

User language	Locale	Example URL
English	en	https://www.binance.com/en/crypto/buy/USD/BTC
简体中文	zh-CN	https://www.binance.com/zh-CN/crypto/buy/CNY/BTC
Português (BR)	pt-BR	https://www.binance.com/pt-BR/crypto/buy/BRL/BTC
Türkçe	en-TR	https://www.binance.com/en-TR/crypto/buy/TRY/BTC

For regional English variants (en-AU, en-IN, en-NG, en-AE, en-NZ, etc.), use the specific regional locale rather than plain en — this ensures the user sees region-appropriate content.

Default to en if the user's language is unclear.

Always include at least one action link when the conversation involves a specific fiat/crypto pair or business type. For general questions, include all relevant links from get_capabilities. Format as a call-to-action, e.g.: "Ready to buy? Buy BTC with USD on Binance"

Presenting Results

• Table format for payment methods (names, limits, pricing); flag suspended methods
• Note that prices are indicative/reference prices
• Respond in the user's language
• Always end with the relevant action link(s)

Price Sorting and Best Value Logic

Price direction depends on the business type — always apply the correct comparison:

Business Type	Better price direction	Rationale
BUY	Lower price is better	You pay less fiat per unit of crypto — same fiat buys more crypto
SELL	Higher price is better	You receive more fiat per unit of crypto sold

When summarizing: for BUY highlight the lowest quotation; for SELL highlight the highest quotation. Example (BUY USD/BTC): $70,236 beats $74,291 — more BTC per dollar.

Wallet Payment Method (BUY)

If the BUY response includes a payment method with code containing WALLET (case-insensitive), it represents buying crypto using the user's Binance fiat wallet balance.

When this occurs, proactively mention:

"One of the available payment methods is your Binance fiat wallet balance. If your wallet doesn't have sufficient funds, you'll need to deposit fiat first. Would you like me to look up the available deposit methods for you?"

If the user confirms, call get_deposit_and_withdraw_payment_methods with businessType=DEPOSIT using the same fiat currency and country, and present the results along with the Deposit action link.

Order & Payment History (Authenticated)

See references/sapi-endpoints.md for authenticated endpoints (order/payment history, deposit/withdraw records). Requires Binance API key and secret.

Country Code Reference

Use ISO 3166-1 alpha-2 codes: BR, GB, DE, FR, JP, KR, AU, etc. Never use US as the country parameter — US users are not supported by Binance fiat payment APIs.

Country Inference Rules

Determine the country parameter using this priority order:

1. Explicit context — If the country is already known from the conversation (user stated it, or inferred in a prior turn), reuse it without re-inferring.

2. Fiat currency → country mapping — Map directly from currency. Examples:

   • SGD → SG, BRL → BR, JPY → JP, KRW → KR, AUD → AU, GBP → GB, CAD → CA, INR → IN, TRY → TR, MXN → MX, NGN → NG
   • EUR → FR (since the user did not specify a country, use FR as the default for EUR)
   • USD → SG (since the user did not specify a country, use SG as the default for USD)

   MANDATORY: US MUST NEVER be used as the country parameter under any circumstances.

3. Empty results — If the API returns no payment methods or an unsupported combination, ask: "No results found for your current settings. Would you like to try a different country? If so, please tell me which country." Then use the country the user provides.
