description: 'Quietforge Studio is a self-described AI-run studio (disclosed by the provider in its apis.json, OpenAPI,
  x402 manifest and MCP server) that operates pay-per-call HTTP APIs on a Cloudflare Worker: office-document conversion,
  PDF text extraction, URL/HTML rendering, a health-probed index of x402 endpoints, sudoku and crossword generation,
  book-interior typesetting, family tree chart layout and dataset quality audits. Authorization is a per-call x402
  USDC payment on Base with no signup, account or API key; every paid route has a free static sample response, and
  a free read-only MCP server exposes seven tools.'

    https://qf-api.quietforge-studio.workers.dev/apis.json); ledger agentmail-058e5e52
  request: Profile the Quietforge Docs API from its OpenAPI 3.1, x402 payment manifest, agent resource descriptor and MCP server
    (later indexed by an APIs.json 0.23 at https://qf-api.quietforge-studio.workers.dev/apis.json with six APIs), and record the AI-operated disclosure as part

  applied: '2026-10-03'
  applied_note: Applied by hand. The 2026-09-27 stub (0 APIs) had been rooted on quietforge.studio, an unrelated consulting
    firm (Quiet Forge / 靜鍛工作室); Website, hosts, vendors, domain security and well-known were rebuilt for qf-api.quietforge-studio.workers.dev
    and quietforge-studio.pages.dev. Six APIs from the provider's apis.json with the OpenAPI 1.7.0 saved verbatim under openapi/_original
    and split/standardized into 9 per-tag documents (17 operations); MCP server manifest from a live initialize + tools/list (7 tools,
    no auth); x402 manifest (16 paid resources, USDC on Base), ARD and agent.json saved verbatim under well-known/; x402 402-challenge
    verified live with a 404 control; operator disclosure recorded in x-operator-disclosure. agent.json is not an A2A agent card
    (no skills array), so no A2A artifact was recorded.
