{"question":"How do I add P0 to Perplexity as a custom remote MCP connector?","answer":"In Perplexity, add a custom remote connector: choose Remote, name it P0 and set the server URL to https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp (HTTPS). The endpoint needs no authentication, so leave authentication on none. The tools you can use through it are free: market search, market statistics and the list of P0's paid products.","url":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/answers/mcp-perplexity","data_as_of":"2026-10-25","facts":[{"label":"P0 MCP endpoint","value":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp","text":"https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp"},{"label":"Transport","value":"streamable-http","text":"Streamable HTTP, JSON-RPC 2.0"},{"label":"Authentication","value":"none required","text":"None required; an optional prepaid access key is accepted as Authorization: Bearer p0k_… (see the notes)"},{"label":"Free tools worth allowing","value":"search_x402_services, x402_market_stats, list_paid_data_products","text":"search_x402_services, x402_market_stats, list_paid_data_products"}],"tables":[{"title":"Steps in Perplexity","columns":["Step","What to do"],"rows":[{"step":"1","what":"Open Perplexity's custom connector form (its help article is \"Adding Custom Remote Connectors\"; the menu path depends on your account)."},{"step":"2","what":"Choose a Remote MCP connector and enter a display name, for example P0."},{"step":"3","what":"Server URL: https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/mcp (Perplexity requires HTTPS)."},{"step":"4","what":"Authentication: none.
