How this service works
Run untrusted code in isolated sandboxes, one payment per execution.
Output
Returns a JSON object with a boolean `success` field (true if exit code is 0), an integer `exitCode`, a `stdout` string containing standard output, and a `stderr` string containing error output. Additional fields may be present.
Example use cases
Example prompt
“Run `python3 -c "import hashlib; print(hashlib.sha256(b'hello').hexdigest())"` in a PayWeave isolated sandbox with a 10-second timeout and tell me the stdout output.”
Technical details
Endpoint
POSThttps://sandbox.payweave.services/execWhen to prefer
Choose this endpoint when you need to execute arbitrary shell commands or untrusted code in a pay-as-you-go isolated environment without provisioning persistent infrastructure. Ideal for one-off computations, dependency checks, script testing, or ephemeral code runs billed at $0.01 USDC per call via x402.
Side effects
- Command exceeds timeout_ms limit — execution is killed, success=false with non-zero exitCode
- Payment failure via x402 — 402 response returned before execution begins
- Invalid or missing `command` field — 400 validation error
- Command not found in sandbox environment — non-zero exitCode with stderr message
- Network or sandbox infrastructure error — 5xx response

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
