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 `data` field with the execution or search result, a `success` boolean, and a `receipt_id` UUID confirming the x402 micropayment was processed.
Example use cases
Example prompt
“Run this JavaScript snippet in a sandboxed environment and give me the output: `function fib(n) { return n <= 1 ? n : fib(n-1)+fib(n-2); } console.log(fib(10));` — pay the $0.001 USDC fee automatically.”
Technical details
Endpoint
POSThttps://api.zuluworksai.com/cf/embedWhen to prefer
Choose this endpoint when you need isolated, pay-per-call code execution (JavaScript or Python) or Bing-backed web search without managing infrastructure, and you want to pay only $0.001 USDC per call via x402 on Base. Ideal for agents that need to run untrusted or ephemeral code safely, or perform lightweight web searches, without committing to a subscription or standing up their own sandbox.
Side effects
- Network access blocked inside sandbox — outbound HTTP calls from code will fail silently or error
- Payment not processed — x402 USDC transaction on Base failed, returning 402 response
- Invalid or malformed prompt — may return success:false with empty data
- Python/JS syntax errors in submitted code — execution fails and error message returned in data
- Cloudflare Worker cold start or timeout — may return a timeout error for long-running scripts
