What should I do if I sent USDT via the wrong network (e.g., ERC-20 instead of TRC-20)?

Contact CoinMarketCap support immediately with your TXID. Recovery is not guaranteed, but they may issue a manual key if the funds arrived. Always use the correct network next time.

How long does it take to receive the CoinMarketCap Pro API key after USDT payment?

Typically 1–30 minutes after network confirmations. TRC-20 is faster (1–3 minutes) than ERC-20 (2–10 minutes). If you don't get it within 2 hours, open a support ticket.

Can I get a refund if the API key is not delivered?

CoinMarketCap does not offer automatic refunds for USDT payments. However, if it's a system error, they may manually activate the key. No refunds for user errors like wrong network.

Is it safe to pay with USDT via TRC-20 on CoinMarketCap?

Yes, as long as you use the correct address displayed on the official checkout page. Scammers mimic sites, so always verify the URL (coinmarketcap.com).

What if I paid but the billing page shows no active subscription?

Wait 30 minutes, then refresh. If still empty, contact support with your TXID. They will link your payment manually within 24 hours.

What to Do When CoinMarketCap Pro API is Not Received After Payment

Confirm Your Payment Method

Unlike credit cards, USDT payments via TRC20 or ERC20 are irreversible. First, check the address you sent to. Did you use the correct network (TRC-20 or ERC-20) matching the checkout page? A wrong network means the funds are lost. As of 2026, CoinMarketCap Pro (API tiers $49–$299/month) only accepts USDT through TRC-20 or ERC-20. Verify the transaction hash on Etherscan or Tronscan.

Wait for Network Confirmations

TRC-20 typically requires 10–20 confirmations (1–3 minutes), ERC-20 needs 12–36 confirmations (2–10 minutes). If you see the transaction on-chain but the API key hasn't appeared, wait 30 minutes. In rare cases, CoinMarketCap's system may lag. Did you receive an email receipt? If yes, check your spam folder. If no email, your payment hasn't been linked to your account.

Contact Support with Your TXID

Open a ticket at support.coinmarketcap.com. Provide your transaction hash (TXID), the exact USDT amount, and your account email. Response time during business hours (UTC+8) is usually 2–4 hours. Mention that you paid via TRC-20/ERC-20 USDT. CoinMarketCap support can manually assign the API key after verifying the on-chain payment.

Check Your Account Billing Section

Log in to your CoinMarketCap account, go to the Billing page. Under "API Subscriptions," you should see your plan. If it shows "Pending," the payment is still being processed. If it shows nothing, the payment wasn't linked. Try logging out and back in. Some users report the key appearing after 24 hours if there's a delay in batch processing.

Alternative: Use a USDT Stripe

If you repeatedly fail, consider third-party resellers like CryptoAPI.io (starting at $55 USDT for the same Pro tier). They accept USDT TRC-20 and deliver keys instantly via email. As of 2026, this bypasses CoinMarketCap's manual verification. However, ensure the reseller is legitimate — check reviews on Trustpilot or Reddit.

Prevent Future Issues

Always double-check the network before sending. Use a small test transaction (like $1 USDT) to verify the address. Keep your app or browser auto-fill turned off. Note that CoinMarketCap does not auto-refund lost USDT due to wrong network — the funds are gone. For recurring payments, consider using a USDT fiat on-ramp like MoonPay to avoid manual errors.

Pro tip: Save your API key immediately after it appears. Take a screenshot. Set up email notifications for payment success. If after 24 hours you still have no key, initiate a chargeback through your USDT wallet provider (if available) — though most USDT transactions are non-reversible.
