agents can now shop for their own tools. is a live marketplace of pay-per-use APIs an agent pays for by the request over x402, settled in USDC from a wallet you control. the catalog covers web search that returns full page contents, working email addresses agents can send from, AI voice calls, image and video generation, and LLM inference across providers, each priced per call with zero subscriptions and zero API key signups. an agent finds a service, pays for one request, and moves on, while every payment clears your spending limits and lands in your audit trail. the browsing works agent-side too: ampersend fetch --pay from the CLI, or point any skill-enabled runtime at the marketplace and let the agent pick its own tooling.
