x402
auteng.ai x402 On-Demand Compute Sandbox is a paid API for AI agents from x402.auteng.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Executes Python or Node.js code in an isolated paid sandbox environment, billed per-call via USDC on Base
Price / call$0.002

How this service works
Execute python code in sandboxed environment (small tier)
Output
Returns a JSON object with stdout, stderr, exit_code, execution_time_ms, sandbox_id, sandbox size, stack used, and any output files (as a files map). On success exit_code is 0 and stdout contains program output.
Example use cases
Example prompt
“Run this Python script in a small sandbox and give me the output: import math; primes = [x for x in range(2,100) if all(x%i!=0 for i in range(2,x))]; print(primes)”
Technical details
Endpoint
POSThttps://x402.auteng.ai/api/x402/computeWhen to prefer
Choose this endpoint when you need to execute arbitrary Python 3.14 or Node.js 24 code in a clean isolated sandbox without managing infrastructure, especially for pay-per-use workloads. Prefer it over self-hosted solutions when you want zero setup, per-call micropayment billing, and configurable compute sizes from 2 to 8 vCPUs.
Side effects
- Non-zero exit_code with stderr if code throws a runtime error or exception
- Timeout error if execution exceeds the specified or default timeout
- Payment failure if USDC balance is insufficient on Base (eip155:8453)
- Invalid stack or size enum value returns a 422 validation error
- Oversized file uploads may be rejected
- Sandbox may fail to start for very large workloads on small size
