  The 2026-05-04 bulk-sweep scaffold, which invented a Free/Pro tier ladder with placeholder request
  quotas. Amazon Lex has no tier ladder at all — it is pure metered usage. Replaced wholesale.

  Prices below are US East (N. Virginia). Every rate in the Price List API is per-region AND per-locale;
  the Price List document carries a separate SKU for each of the 30+ supported locales. The en-US rates
  are the headline rates published on the pricing page.

    There is no subscription and no tier to choose. Amazon Lex bills per request processed by a bot,
    metered by interaction mode (request/response vs streaming) and by input/output modality
    (speech/text/DTMF). Bot building, versioning, exporting and testing carry no charge; only
    conversation traffic and Automated Chatbot Designer training do.

      Requests served by a globally-replicated bot carry a separate higher rate — the Price List
      publishes parallel "-GR" SKUs for every mode. en-US examples: speech request/response 0.0060 (vs
      0.0040), text request/response 0.0011 (vs 0.00075), streaming speech 0.0094 (vs 0.0065),
      streaming text 0.0030 (vs 0.0020).

    to eligible services including Amazon Lex. The free plan runs for 6 months after account creation;
    all credits must be used within 12 months of account creation.

note: >-
  Worth recording as a discoverability fact: Amazon Lex's prices are genuinely machine-readable. The AWS
  Price List API serves the full SKU set as JSON with no authentication, which is why this artifact is
  method: probed rather than searched. The HTML pricing page is the weaker source of the two — it
  renders several rates as unresolved template tokens ({priceOf!lex/lex!Text!to!Text!...}) to a plain
  fetch, while the JSON gives every rate for every region and locale.
