How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns a list of flash loan arbitrage opportunities, each with the token path, protocols involved, number of hops, estimated net profit in USD, confidence score, and chain(s) involved. Results are filtered by the caller's minimum profit and confidence thresholds.
Example use cases
High-confidence single-chain arb hunt
“Scan Ethereum for flash loan arbitrage on the top 50 tokens, show me only opportunities with at least 80 confidence and a minimum $100 net profit, keeping it to 2 hops max.”
Cross-chain arbitrage discovery
“Find cross-chain arbitrage opportunities across Ethereum, Arbitrum, and Base for ETH and USDC, with at least $50 profit and confidence above 60.”
Low-threshold multi-hop opportunity scan
“Scan all major chains for any flash loan arb opportunities with at least $5 net profit, up to 4 hops, and include cross-chain routes — I want to see everything with a confidence score above 50.”

Endpoint
POSThttps://chat.sperax.io/api/x402/tools/flash-loan-scanner/scanArbitrageOpportunities?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, AI-scored flash loan arbitrage opportunity detection across DeFi protocols on EVM chains. It is ideal for autonomous trading agents, DeFi researchers, or bots that need ranked, confidence-scored arb routes without building their own price-feed aggregation. It's pay-per-call with no API key required, making it well-suited for infrequent or on-demand scans.
Side effects
- No opportunities found meeting the specified thresholds — try lowering minProfitUsd or minConfidence
- Invalid chain name provided — check supported chain identifiers
- Payment failure via x402 protocol — insufficient USDC balance or payment not accepted
- maxHops value out of acceptable range — use a value between 1 and a platform maximum
- Network timeout if scanning many chains simultaneously
