Frequently Asked Questions About Buying API3

How do I buy API3 with a credit card?

Select API3 as the cryptocurrency you want to receive and enter the amount in your preferred fiat currency. Swapzone will display offers from on-ramp providers like MoonPay, Guardarian, Banxa, and Transak – each showing the rate, fees, and estimated delivery time. Choose an offer, provide your wallet address, and complete the payment on the provider's secure checkout. Most card purchases deliver API3 to your wallet within 5–15 minutes.

Is KYC required to buy API3?

KYC requirements depend on the provider you choose and your purchase amount. Some providers like Guardarian offer purchases up to €700/day without full identity verification. Others like MoonPay and Transak offer tiered KYC – basic verification for smaller amounts, full KYC for higher limits. On Swapzone, you can see provider requirements before selecting an offer. Swapzone itself does not require registration or collect your personal data – all verification is handled by the provider.

What payment methods can I use to buy API3?

Available payment methods depend on the provider and your region. Common options include: credit/debit cards (Visa, Mastercard), Apple Pay, Google Pay, bank transfers (SEPA in Europe, ACH in US, Faster Payments in UK), and local methods like PIX (Brazil), iDEAL (Netherlands), or Revolut Pay. Swapzone aggregates offers from multiple providers, giving you access to various payment options in one place – select your preferred method to see which providers support it.

How long does it take to receive API3 after buying?

Delivery time depends on the provider and payment method. Card payments (Visa, Mastercard, Apple Pay, Google Pay) typically complete within 5–15 minutes. SEPA Instant and Faster Payments usually process within minutes to hours. Standard bank transfers (SEPA, ACH) may take 1–3 business days. Each offer on Swapzone displays the estimated transaction time so you can choose faster providers when speed matters.

What is the minimum amount of API3 I can buy?

Minimum purchase amounts vary by provider – typically ranging from $10 to $50 USD equivalent. Maximum limits depend on the provider, payment method, and your verification level. For example, MoonPay may allow up to $20,000 for verified users, while no-KYC purchases on Guardarian are capped at €700/day. Swapzone displays minimum and maximum amounts for each offer, making it easy to find a provider that fits your budget.

Is it safe to buy API3 through Swapzone?

Swapzone is a non-custodial aggregator – we never handle your funds, payment data, or cryptocurrency. When you buy API3, you deal directly with licensed on-ramp providers (MoonPay, Guardarian, Banxa, Transak). These providers are regulated, hold financial licenses, and use bank-level security including 3D Secure for card payments. Your crypto goes directly from the provider to your personal wallet. Swapzone uses SSL encryption and displays user ratings for each provider to help you make informed choices.

Can I buy API3 without verification?

Some providers offer limited purchases without full KYC verification. For example, Guardarian allows purchases up to €700/day with minimal verification, and Transak offers "Lite KYC" requiring only basic details like name and billing address. However, these options have lower purchase limits. For larger amounts, providers typically require ID verification to comply with financial regulations. On Swapzone, you can compare offers and see verification requirements before starting.

What fees will I pay when buying API3?

When buying API3, fees typically include: the provider's service fee (usually 1–5% depending on provider and payment method), payment processing fees (card payments often have higher fees than bank transfers), and blockchain network fees for sending crypto to your wallet. Swapzone charges 0% platform fee – we show you the final amount you'll receive after all provider fees, so you can compare true costs across different offers. Card payments typically have higher fees (3–5%) while bank transfers are cheaper (1–2%).

What wallet do I need to buy API3?

You need a wallet that supports API3 to receive your purchase. Options include: hardware wallets (Ledger, Trezor) for maximum security, software wallets like MetaMask, Trust Wallet, or Exodus, and mobile wallet apps. Many of these wallets already integrate with the same providers Swapzone aggregates. Have your wallet address ready before starting – double-check it carefully, as cryptocurrency transactions cannot be reversed.

Why should I use Swapzone to buy API3?

Swapzone aggregates offers from multiple on-ramp providers (MoonPay, Guardarian, Banxa, Transak, and others), letting you compare rates, fees, and delivery times in one place.
