Technical details
Endpoint
GEThttps://wallet-intel-api-production-3ec7.up.railway.app/api/v1/arb-spreads/%7Bsymbol%7DWhen to prefer
Use this endpoint when you need real-time cross-exchange price spread and arbitrage opportunity data for a specific crypto token. Ideal for trading bots, opportunity scanners, or any workflow where you need to know which exchange offers the best buy/sell price and how much profit an arb trade could yield. Prefer over generic price APIs when the spread and profit calculation matter, not just the spot price.
Side effects
- Unknown or unsupported token symbol returns an error or empty result
- Exchange data unavailable due to upstream feed outage reduces exchange count
- Rate limiting or payment failure returns 402 Payment Required
- Symbol missing from query returns a 400 Bad Request
- Very low-liquidity tokens may have only 1-2 exchanges responding, making spread unreliable
