How this service works
Pay-per-call x402 execution primitives (USDC on Base). Code execution runs in isolated Cloudflare Dynamic Worker sandboxes (JavaScript + Python, network blocked). Web search backed by Bing RSS. Self-hosted facilitator.
Output
Returns a JSON object with a 'data' field containing the routing result, a 'success' boolean, and a 'receipt_id' UUID confirming the paid x402 execution
Example use cases
Multi-hop token swap across three chains
“I need to move 1000 USDC from Ethereum to Optimism but cheaper than direct bridging—what's the optimal route that might hop through Base or Arbitrum to minimize fees?”
Asset bridging cost comparison tool
“Should I bridge my ETH from Mainnet to Polygon directly or would it be cheaper to go through Arbitrum first? Show me the best path.”
Real-time cross-chain arbitrage routing
“I spotted an opportunity to buy USDC cheap on Base and sell it on Ethereum—calculate the fastest and cheapest route to move my funds and execute the arbitrage.”
Technical details
Endpoint
POSThttps://api.zuluworksai.com/exec/cross-chain-routeWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription cross-chain route computation backed by an isolated execution environment and x402 micropayment rails on Base; ideal for agents that want to pay only for what they use without API key management
Side effects
- Payment failure: insufficient USDC balance on Base causes 402 rejection
- Invalid prompt: vague or malformed routing query returns empty or unhelpful data object
- Network-blocked sandbox: any prompt requiring live on-chain data fetches may fail since network is blocked inside the execution sandbox
- Rate limiting or facilitator downtime: self-hosted facilitator may be unavailable
- Malformed response: success=false with empty data if route cannot be computed
