  title: Fetchgate Read API
  version: 0.1.0
  summary: Web-content API and x402 digital-goods storefront for AI agents.
  description: 'Fetch clean Markdown or structured metadata from any URL, server-side, with scripts/nav/ad boilerplate stripped out. Also a machine-payable storefront: GET /v1/products for the catalog, GET /v1/buy/:id to pay per product via x402 (USDC on Base) and receive a signed download URL.'
  x-guidance: 'Two independent surfaces. (1) Web reader: GET /v1/read?url=... for Markdown, GET /v1/meta?url=... for structured metadata — free up to 30 calls/day/IP, then $0.002 (/v1/read) or $0.001 (/v1/meta) per call via x402 v2 (send a PAYMENT-SIGNATURE header after receiving a 402; legacy X-PAYMENT is also accepted). (2) Digital-goods store: GET /v1/products lists the catalog (no payment); GET /v1/buy/:id with a real id from that catalog always requires payment — send PAYMENT-SIGNATURE to get a 402 challenge, pay it, and the 200 response carries a time-limited signed downloadUrl to fetch the file from. Everything is also reachable as MCP tools at POST /mcp (read_url, get_metadata, scan_for_prompt_injection, search_x402_services, check_x402_endpoint, check_base_token, list_products, get_purchase_info, get_agent_census, scan_mcp_server).'
