Endpoint
POSThttps://x402.donnyautomation.com/arbitrum/route?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, fee-adjusted best-execution routing or arbitrage spread data specifically on Arbitrum One across SushiSwap and Uniswap v3 fee tiers. Prefer it over generic price feeds when you need venue-level comparison, not just a single spot price. Choose it over the Polygon or Base variants when your trading or arbitrage strategy targets Arbitrum One / ARB L2.
Side effects
- Unsupported or invalid token pair symbol returns an error (e.g. pair not listed on any supported DEX)
- Insufficient liquidity on one or both sides results in no viable route or degenerate spread
- Network congestion or RPC failures on Arbitrum One may cause stale or unavailable data
- Malformed pair query parameter (wrong format, missing slash) returns a schema validation error
- Payment failure (x402 micropayment not settled) results in 402 response before data is returned
