mppBuild with MPP (Machine Payments Protocol) - the open protocol for machine-to-machine payments over HTTP 402. Use when developing paid APIs, payment-gated content, AI agent payment flows, MCP tool payments, pay-per-token streaming, or any service using HTTP 402 Payment Required. Covers the mppx TypeScript SDK with Hono/Express/Next.js/Elysia middleware, pympp Python SDK, and mpp Rust SDK. Supports Tempo stablecoins, Stripe cards, Lightning Bitcoin, and custom payment methods. Includes charge (one-time) and session (streaming pay-as-you-go) intents. Make sure to use this skill whenever the user mentions mpp, mppx, machine payments, HTTP 402 payments, Tempo payments, payment channels, pay-per-token, paid API endpoints, or payment-gated services.

An AI model provider charges per inference request using MPP's charge intent. Clients automatically pay via HTTP 402 without API keys or manual billing. Ideal for LLM-as-a-service platforms.
A real-time language model service uses MPP session intents to bill customers based on tokens generated during a streaming session. Enables granular usage-based pricing for chatbots and content generation APIs.
Premium content platforms (e.g., research papers, video streams) gate individual articles or streams behind MPP charge intents. Users pay per piece without subscription commitments, using stablecoins or cards.
A middleware service that wraps existing APIs (e.g., OpenAI, Stripe) with MPP payment gating. Downstream clients pay the proxy per request, enabling reselling or metered access without direct subscriptions.
AI agents autonomously pay for tool calls, data feeds, or compute resources via MPP. Agents use session intents for streaming data and charge intents for one-time operations, enabling fully automated machine-to-machine commerce.
Charge a fixed amount for each API call, settled instantly via MPP. Revenue scales with usage, and customers avoid upfront commitments. Suitable for data enrichment, image processing, or verification services.
Bill customers based on consumption (e.g., tokens, bandwidth) during a session using MPP's session intent. Revenue increases with usage duration or volume, ideal for AI inference or content delivery.
Provide a white-label payment gateway that other APIs integrate via MPP. Earn transaction fees per payment processed. Scalable to numerous merchants with minimal integration effort.
💬 Integration Tip
Start with the mppx TypeScript SDK and test with Tempo test tokens in a sandbox environment before using real methods. Enable both charge and session intents to support a variety of use cases from the start.
