Technical details
Endpoint
GEThttps://market.memoryapi.org/x402/market/cex_arbWhen to prefer
Use this endpoint when you need real-time cross-exchange cryptocurrency arbitrage data to identify buy/sell price discrepancies across major CEXes. Prefer this over manual price comparison or generic ticker endpoints when the specific goal is finding exploitable price gaps between exchanges rather than just tracking a single price.
Side effects
- Exchange data unavailable or stale — returns partial results or error if one or more exchanges are unreachable
- Invalid or unsupported trading pair — returns empty results or 404
- Rate limit exceeded — returns 429 if called too frequently
- Payment not processed — returns 402 if x402 payment header is missing or insufficient
