What problem does it solve? Agents often need paid API access for tasks like web search, data enrichment, or blockchain analytics, but lack API keys and a safe way to spend money. This Skill provides user-authorized paid HTTP access through a local Pay MCP server, where every payment requires local approval such as Touch ID before any stablecoins move. ## Core Features & Use Cases - Provider Discovery: Use search_catalog and list_catalog to find ranked, curated API providers across categories like search, scraping, enrichment, media generation, maps, and BigQuery. - Paid HTTP Requests: The curl tool handles HTTP 402 payment challenges automatically, preparing the payment and requesting local user approval before settling in USDC, USDT, or CASH. - API Monetization: Developers can run pay server start with a YAML spec to put their own API behind HTTP 402 payments and publish it to the pay-skills registry. - Use Case: When asked for the volume of USDC moved on Solana last week, the agent searches the catalog for a blockchain analytics or BigQuery provider, plans a single low-cost paid call, and retrieves current data instead of scraping stale dashboards. ## Quick Start Ask the agent to use pay to search the catalog for a provider matching your task, then approve the small payment when prompted.
