PayWeave Sandbox · Pay-per-call Code Execution
x402
PayWeave Sandbox · Pay-per-call Code Execution is a paid API for AI agents from sandbox.payweave.services, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Executes arbitrary source code in an isolated sandbox environment, returning stdout/stderr logs and rich outputs, charged per execution via x402 micropayment.

StatusUnknown
How this service works
Run untrusted code in isolated sandboxes, one payment per execution.
Output
Returns a JSON object with a success boolean, the language used, captured stdout and stderr as ordered arrays, Jupyter-style rich results (including base64 PNG images, HTML, or text from the final expression), and a structured error object (name, message, traceback) if execution failed — all null on success.
Example use cases
Example prompt
“Run this Python script in an isolated sandbox and give me the output — it generates a bar chart using matplotlib: `import matplotlib.pyplot as plt; plt.bar(['A','B','C'],[3,7,2]); plt.savefig('out.png')` — set a 10-second timeout and pass ENV_MODE=production as an environment variable.”
Technical details
Endpoint
POSThttps://sandbox.payweave.services/runWhen to prefer
Choose this endpoint when you need to execute arbitrary or untrusted code in a secure, isolated environment on a pay-per-use basis without provisioning persistent infrastructure. Ideal for AI agents that need to run generated code snippets, data analysis scripts, or chart-rendering code dynamically. The micropayment model (x402, $0.01 USDC) makes it cost-effective for low-frequency or one-off executions compared to spinning up a persistent container.
Side effects
- Code raises an unhandled exception — success=false, error contains name/message/traceback
- Execution exceeds timeout_ms — process is killed, success=false with timeout error
- Unsupported language specified — error returned indicating unknown interpreter
- Payment fails or is insufficient via x402 — 402 response before execution begins
- Malformed request body missing required 'code' field — validation error returned
