  Xoserve does not publish per-plan prices. Pricing for the Supply Point Quantities API is set by an
  annual allowance of API calls ("hits") categorised into bands A to F, and the provider states
  explicitly that "the pricing of these bands will be detailed in your contract" — the band ceilings
  are public, the money is not. The three Gas Enquiry Service APIs are not priced by Xoserve at all:
  they are charged under the REC Charging Statement administered by the Retail Energy Code Company.
  Every plan is gated on regulated eligibility, not on payment: all three portal Products carry both
  subscriptionRequired=true and approvalRequired=true.

notes: >-
  Only figures Xoserve actually publishes are recorded. The band allowances are transcribed verbatim
  from the "How much does the Supply Point Quantities API cost?" table on the Gas APIs page. No price
  per band, no currency amount and no free tier is asserted, because none is published.
