  "description": "`npx atxp agent register` creates an agent account with an `@atxp.email` address, an Ethereum wallet and $5 starting credit; `npx atxp fund` returns USDC deposit addresses and a Stripe payment link. Tools are pay-per-use (README examples: search/image $0.001–$0.05, email $0.01, SMS $0.05). An OpenAI-compatible LLM gateway is at `llm.atxp.ai`. The MIT-licensed SDK (`@atxp/client`, `@atxp/server`, `@atxp/express`, `@atxp/x402`, ...) lets developers charge for MCP servers; supported chains include Base, World Chain, Polygon and Solana. npm `atxp` 1.29.0.",
