Mpp Agent — Pay HTTP 402 APIs via Machine Payments Protocol (MPP)
Mpp Agent — Pay HTTP 402 APIs via Machine Payments Protocol (MPP)
Start with meaning, then move to detail.
This lesson explains Mpp Agent — Pay HTTP 402 APIs via Machine Payments Protocol (MPP) as part of Hermes internals and extension points. You will learn what it does, when it matters, and the smallest safe test that proves it works.
If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?
For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.
For advanced readers, inspect Skill metadata, Reference: full SKILL.md, When to Use, then verify failure modes and version compatibility.
Know Python, Git, and basic project structure before changing code.
A clear outcome before you read.
- Understand Mpp Agent — Pay HTTP 402 APIs via Machine Payments Protocol (MPP) without assumed prior knowledge.
- Separate the source description from what still needs testing in your environment.
- Read the first command and identify its inputs and outputs before copying it.
Short definitions before the details.
- Skill
- An instruction bundle that teaches Hermes a repeatable workflow without necessarily adding an external service.
