Server instructions

PayAPI Market lists APIs an AI agent can call and pay for by itself, per request, in USDC on Base. No API key and no account are needed to call a listed API. Use search_apis to find something by free text, list_apis to browse a category, and get_api to fetch one listing in full. search_apis and list_apis default to settlement-verified listings only. Settlement-verified means PayAPI Market paid for a real call to that listing from its own wallet and received real product back, with the payment recorded on-chain. Pass verified_only=false to see live-but-unverified listings too; they are labelled, never silently mixed in. These tools are free and read-only. They never spend money. To actually use a listed API, take its base_url, request it unpaid to receive the HTTP 402 challenge, then pay per that challenge with your own wallet. payment_verified is per listing, not per route: a listing with several routes may have had only one verified.
