model: 'Every machine surface (MCP servers, A2A agents, gate register, JIDEC ledger, Claude plugin, npm client) is free with no account or key. Money is charged on the human side: per-document consumer appraisals via PayPal, and fixed monthly B2B plans (setup + subscription, tax included) for contractors listed on the Yakumo mall. The provider states on nearly every page that it takes no referral fee, listing commission or success fee.'
summary: >-
  Prices as published on 2026-09-19. The B2B plans page states all amounts are tax-inclusive, that the subscription
  starts on the "apply" button, that the setup fee is invoiced separately after application, and that plans can be
  cancelled any time with no minimum term. The verify-directory page states the gate check is "FREE · NO ACCOUNT ·
  NO API KEY" and "free forever, listing included"; llms.txt notes that "price validation is a separate, paid tier"
  whose price is not published.
