Execute commands in a Modal serverless sandbox via MPP-paid API calls.
What it does
This endpoint exposes Modal's serverless sandbox execution capability through the Merchant Payment Protocol (MPP), allowing agents to run commands in an isolated cloud sandbox environment. Modal is a platform for serverless GPU compute, sandboxed code execution, and AI/ML workloads. The endpoint is designed to accept a command and execute it within a Modal sandbox, returning the result.
However, at the time of probing, the endpoint at https://modal.mpp.tempo.xyz/sandbox/exec did not return the expected 402 MPP payment challenge on either HEAD or GET requests — instead returning 404 Not Found. The provider's root domain and all documentation paths also returned 404. This suggests the endpoint may not yet be deployed, may have been moved, or may only respond to POST requests that were not probed. No OpenAPI schema, pricing information, or documentation was available from the crawl.
Because of the lack of a live 402 challenge and the absence of any supporting documentation or schema, the listing is effectively a stub based solely on the Bazaar catalog metadata. Users and agents should verify availability before attempting integration.
Capabilities
Use cases
- —Running arbitrary commands in an isolated cloud sandbox for AI agent workflows
- —Executing untrusted or experimental code in a secure serverless environment
- —Performing on-demand compute tasks without managing infrastructure
Fit
Best for
- —AI agents needing on-demand sandboxed code execution
- —Developers who want pay-per-call serverless command execution
- —Workflows requiring isolated environments for untrusted code
Not for
- —Long-running persistent server workloads
- —Use cases requiring guaranteed low-latency responses with no cold start
Quick start
# Endpoint may only accept POST; verify liveness first.
curl -X POST https://modal.mpp.tempo.xyz/sandbox/exec \
-H "Content-Type: application/json" \
-d '{"command": "echo hello world"}'Example
Request
{
"command": "echo hello world"
}Endpoint
Quality
The endpoint returned 404 on both HEAD and GET probes, no 402 MPP challenge was captured, and all documentation/root paths returned 404. The listing is based entirely on the Bazaar catalog title and description with no schema, pricing, or live confirmation.
Warnings
- —Endpoint did not return a 402 MPP payment challenge on HEAD or GET — it may only respond to POST, or it may not be live.
- —All crawled pages (root, /docs, /api, /pricing, /README) returned 404 Not Found.
- —No pricing, schema, or documentation is available; this listing is a stub.
- —The endpoint may have been moved or is not yet deployed.
