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
A JSON object containing a 'success' boolean, a 'receipt_id' UUID confirming the paid execution, and a 'data' object holding the result of the executed code or web search. The receipt_id serves as proof of payment and task completion for auditing.
Example use cases
Example prompt
“Run this JavaScript snippet in a secure sandbox and return the result: 'const nums = [1,2,3]; console.log(nums.reduce((a,b)=>a+b,0));' — I'm okay with spending $0.01 USDC for the call.”
Technical details
Endpoint
POSThttps://api.zuluworksai.com/exec/agent-passportWhen to prefer
Choose this endpoint when you need sandboxed, pay-per-call code execution (JavaScript or Python) or lightweight Bing RSS web search billed at $0.01 USDC via x402 on Base. Prefer it for disposable, stateless compute tasks where network isolation is acceptable and cost predictability per call matters. Not suitable for tasks requiring outbound network calls from within the execution environment or persistent state.
Side effects
- Prompt missing or empty — returns validation error
- Network access attempted inside sandbox — blocked by Cloudflare Worker isolation
- Insufficient USDC balance or x402 payment failure — call rejected before execution
- Malformed JavaScript or Python syntax — execution error returned in data payload
- Bing RSS unavailable — web search calls may return empty or error data
- Timeout in sandbox execution — long-running code may be terminated
