Technical details
Endpoint
GEThttps://silverback-x402.onrender.com/api/v1/arbitrage-scannerWhen to prefer
Use this endpoint when you need to identify price inefficiencies between DEX aggregators for a specific token pair on Base chain, especially before executing a swap to determine if arbitrage is viable. Prefer this over general price feeds when you specifically need cross-aggregator spread analysis rather than a single best price.
Side effects
- Missing required tokenIn or tokenOut query parameters returns validation error
- Unsupported or unrecognized token symbol/address returns error
- No liquidity found for the token pair results in empty or null data
- Payment of $0.03 USDC not provided returns 402 Payment Required
- Service temporarily unavailable on render.com free tier (cold start delays)
