Machine payments

Test machine-to-machine payment flows before production.

ArgentShell is a terminal utility for teams building agent-payable products. It helps developers exercise MPP endpoints, inspect payment challenges, and debug integration behavior from a focused command-line workflow.

What it does

Focused capabilities. Clear outcomes.

A faster way to validate payment-aware API behavior before an autonomous client depends on it.

Exercise MPP endpoints

Run payment-aware requests directly from a focused terminal workflow.

Inspect HTTP 402 challenges

See payment requirements and response behavior without guessing what the endpoint returned.

Smoke-test integrations

Validate agent-payment behavior before production clients depend on the flow.

Debug machine commerce

Iterate on machine-to-machine payment logic with a repeatable request loop.

Typical workflow

From intent to a working outcome.
