  Clerk.io's published plans and pricing, read from https://www.clerk.io/pricing on 2026-08-13. This file
  REPLACES a fabricated Free/Professional/Enterprise scaffold written by the 2026-05-04 bulk sweep, whose
  tier names, quotas (1,000 and 100,000 requests/month) and rate limits (10 and 100 req/min) were
  invented and appear nowhere in Clerk.io's material.

    Clerk.io does not sell named subscription tiers. It sells five products a la carte - Search,
    Recommendations, Chat, Email and Audience - each metered on its own usage unit, each priced by a
    volume band selected in an interactive calculator. A customer buys any subset and can add products
    at any time. Clerk.io states "you only pay for the amount you use".

  price_transparency_note: >-
    PRICES ARE NOT MACHINE-READABLE. The per-band monthly price and the per-1,000-unit rate are computed
    client-side by a JavaScript calculator; the served HTML carries 0 for every price and exposes no JSON
    price feed. The volume BANDS below are published in the page markup and are recorded verbatim; the
    amounts are not, and are deliberately left unstated here rather than guessed.

api_access:
  gated_by_plan: false
  note: >-
    The REST API is not sold as a separate line item and is not tiered. Any store gets a public and a
    private API key; API usage is metered through whichever products the store bought (a /search/search
    call consumes a Search unit, a /recommendations/* call consumes a Recommendations unit). There is no
    published free API tier and no published request quota or rate limit attached to any plan.
