BoltzPay — The Trust Layer for the Paid Internet

# BoltzPay > The first trust registry and universal SDK for paid APIs. Supports x402, L402, and MPP protocols. BoltzPay solves two problems: 1. **Discovery** — How do AI agents find paid API endpoints? The BoltzPay Registry scans, scores, and indexes every paid API across x402, L402, and MPP protocols. 2. **Payment** — How do AI agents pay for API calls? The BoltzPay SDK handles protocol detection, wallet management, budget enforcement, and payment execution in a single `fetch()` call. ## Registry Live trust registry at status.boltzpay.ai. Continuously scans paid API endpoints across three protocols (x402, L402, MPP). Each endpoint receives an EWMA-based trust score (0-100). REST API available. - Registry: https://status.boltzpay.ai - Registry API: https://status.boltzpay.ai/api/endpoints - Live stats: https://status.boltzpay.ai/api/stats ## SDK Open-source TypeScript SDK. Detects payment protocols automatically, routes to the correct adapter, and executes payment — all behind a single `fetch()` call. ``` npm install @boltzpay/sdk ``` ```typescript import { BoltzPay } from "@boltzpay/sdk"; const agent = new BoltzPay({ wallets: [{ type: "tempo", name: "main", tempoPrivateKey: process.env.TEMPO_KEY! }] }); const res = await agent.fetch("https://api.example.com/data"); console.log(await res.json()); ``` ### Packages - `@boltzpay/sdk` — Core SDK (fetch, discover, openSession, wrapMcpClient) - `@boltzpay/cli` — CLI tool (discover, fetch, diagnose, wallet-status) - `@boltzpay/mcp` — MCP server exposing SDK tools to AI agents ## Key Links - Website: https://boltzpay.ai - Registry: https://status.boltzpay.ai - npm: https://www.npmjs.com/package/@boltzpay/sdk - Docs: https://docs.boltzpay.ai - Full LLM documentation: https://boltzpay.ai/llms-full.txt - Registry LLM documentation: https://status.boltzpay.ai/llms-full.txt ## Protocols Supported | Protocol | Description | Wallet Types | |----------|-------------|-------------| | x402 | HTTP 402 + on-c
