MEXC is fast to list new tokens and exposes a straightforward REST + WebSocket API for spot and futures. Here's how to get keys and what it costs.

What the API does & cost

Use	Cost
Market data (REST/WS)	Free
Spot maker/taker	~0.0–0.1%
Futures taker	~0.02–0.06%
API access	Free

⚠️ The MEXC API is free to use — you only pay trading fees on the trades it places. Fees and limits change; confirm on the official docs. Market-data (read-only) endpoints cost nothing. · Report outdated price →

How to get your MEXC API keys (step by step)

1. Sign up / log in at mexc.com and complete verification.
2. Go to Account → API Management and click Create API.
3. Label the key, choose permissions (Read / Trade) and add an IP allow-list.
4. Copy the Access Key and Secret Key — the secret shows once.
5. Keep withdrawals off for API trading keys.

Quick test

# public market data — no key needed
curl "https://api.mexc.com/api/v3/ticker/price?symbol=BTCUSDT"

Security — read this

Never share your secret — regenerate it if leaked. For data-only bots enable read-only. Always whitelist your server IP and disable withdrawals on API keys unless you truly need them — a leaked withdraw-enabled key can drain your account.

Alternatives

MEXC is great for early listings; for liquidity on majors use Binance or OKX.
