What problem does it solve?

This skill resolves the friction of accessing premium APIs that require payment via the Machine Payments Protocol (MPP) by automating the handling of HTTP 402 Payment Required challenges.

Core Features & Use Cases

  • Automated Payment Handling: Automatically detects and responds to HTTP 402 challenges using configured wallet providers.
  • Multi-Client Support: Integrates with various payment tools like Tempo, Privy, AgentCash, and mppx to suit different funding and security needs.
  • Use Case: When an agent encounters a pay-per-request API, this skill negotiates the payment handshake, attaches the necessary credentials, and retrieves the requested data without interrupting the user workflow.

Quick Start

Use the mpp-agent skill to pay for the API request at the provided URL using your configured mppx account.

FAQPage Schema
How do I automate payments for HTTP 402 API responses?▼

Automated payments for HTTP 402 API responses are handled by detecting payment challenges and automatically attaching wallet credentials to fulfill per-request micropayments. This process uses the Machine Payments Protocol to negotiate the handshake and retrieve the gated data without interrupting your workflow.

What is the Machine Payments Protocol for API access?▼

The Machine Payments Protocol (MPP) is a standard for automating per-request micropayments to access premium web services. It enables autonomous agents to negotiate HTTP 402 Payment Required challenges by attaching payment credentials directly to API requests.

Can I use Tempo or AgentCash wallets for automated micropayments?▼

Yes, you can use Tempo, AgentCash, Privy, or mppx for automated micropayments. The skill supports multi-client wallet integrations to handle HTTP 402 challenges, allowing you to choose the provider that best fits your funding and security needs.

Do I need Node.js to handle MPP payment handshakes?▼

Yes, Node.js is required as a runtime environment to execute the automated payment handshake logic. This dependency enables the skill to process HTTP 402 challenges and interface with your configured wallet providers for per-request API access.

How do autonomous agents pay for per-request API services?▼

Autonomous agents pay for per-request API services by utilizing the Machine Payments Protocol to automatically negotiate HTTP 402 challenges. When encountering a paywall, the agent uses configured wallet integrations to process the micropayment and retrieve the requested data seamlessly.
