Best for

  • MEXC is the primary connector choice for new token listing strategies, including first-minute price discovery, listing-gap arbitrage, and basket rotation into freshly-launched assets.
  • It suits high-throughput altcoin scanners that need to monitor hundreds of low-cap pairs for breakout conditions.
  • Barfinex users building token-launch signal pipelines or running multi-exchange listing monitors will find MEXC's breadth of coverage essential for completeness.

Important

Permissions required: Read + Trade.
MEXC uses HMAC-SHA256 signed requests.
Note that MEXC imposes strict restrictions on API access by jurisdiction — users in the United States are not permitted to use the MEXC API.
Spot rate limits are relatively generous (typically up to 500 requests/sec for public endpoints), but futures endpoints have tighter limits.
MEXC futures are on a separate contract account and require distinct API activation.
Always verify the listing status of target pairs before deploying a strategy, as MEXC delists tokens frequently.
