Check the status of a Modal serverless sandbox via pay-per-call MPP endpoint.
What it does
This endpoint is listed as an MPP (Micropayment Protocol) gateway to Modal's sandbox status API. Modal is a serverless GPU compute platform used for sandboxed code execution and AI/ML workloads. The intended purpose of this endpoint is to let callers retrieve the current status of a Modal sandbox instance, presumably returning whether a sandbox is running, stopped, or in an error state.
However, during probing the endpoint returned HTTP 404 on both HEAD and GET requests rather than the expected 402 payment challenge. The provider's root domain (modal.mpp.tempo.xyz) also returns 404 across all tested paths including /docs, /api, /pricing, and /README. No OpenAPI schema, documentation, or MPP challenge metadata was captured. This means the endpoint is currently not responding with the standard MPP wire protocol and cannot be confirmed as live or functional.
Because no payment challenge was returned, pricing details (settlement method, token, amount) are unknown. The endpoint is expected to settle via Tempo L2 based on the domain pattern (mpp.tempo.xyz), but this cannot be verified from the probe data. Users should treat this listing as a stub until the endpoint begins returning proper 402 challenges.
Capabilities
Use cases
- —Checking whether a Modal sandbox instance is running or stopped
- —Monitoring sandbox health in automated pipelines
- —Polling sandbox readiness before submitting workloads
Fit
Best for
- —Developers using Modal for sandboxed code execution
- —Automated orchestration systems that need sandbox state
- —AI/ML pipeline monitoring
Not for
- —Users needing to launch or manage sandboxes (this is read-only status)
- —Anyone requiring a currently live and verified endpoint
Quick start
# Endpoint is currently returning 404; not live.
# Expected usage once live:
curl -X GET https://modal.mpp.tempo.xyz/sandbox/statusEndpoint
Quality
The endpoint returned 404 on all probe methods and no MPP challenge, documentation, schema, or pricing was captured. The listing is effectively a stub with only a title and one-line description from the Bazaar record.
Warnings
- —Endpoint returned 404 on HEAD and GET — no MPP 402 challenge captured; endpoint appears not live.
- —Root domain and all documentation paths return 404.
- —No pricing, schema, or authentication details available.
- —Listing is a stub; do not rely on this endpoint being functional.
