How this service works
Bounded sandbox.run discovery challenge
Output
Returns a JSON object with a 'state' field (e.g. RECEIPTED), a 'result' containing execution output (kind, exitCode, stdoutBase64), a 'receipt' with settlement status, a 'replayed' boolean, and the 'productId' used for the run.
Example use cases
Automated agent task validation
“Execute this sandbox job on Clervo and tell me whether it completed with exit code 0 and what it printed to stdout.”
Paid sandboxed code execution
“I want to run a quick sandboxed script through Clervo's execute endpoint and get the output back — make sure the payment settles and give me the receipt.”
Agent pipeline outcome verification
“Trigger a Clervo sandbox run for my agent workflow and confirm the state came back as RECEIPTED with a settled status before moving to the next step.”
Technical details
Endpoint
POSThttps://api.clervo.dev/v1/sandbox/executeWhen to prefer
Choose this endpoint when you need to execute a sandboxed task or code run within the Clervo agent infrastructure ecosystem, particularly when you require a verifiable outcome receipt with settlement confirmation via x402 micropayments. Ideal for agent pipelines that need auditable, paid execution with structured stdout and exit code output.
Side effects
- Execution failure: non-zero exitCode returned with error output in stdoutBase64
- Payment not settled: receipt.settlement.status not 'settled', indicating x402 payment issue
- Invalid payload: malformed request body causes rejection before execution
- Timeout: sandbox execution exceeds allowed time limit
- Authentication failure: missing or invalid x402 payment header returns 402 error
