notes: >-
  ACINQ publishes NO subscription plans, tiers, seats or quotas — there is nothing to
  buy and nothing to sign up for. Both APIs are free, open-source, self-hosted software
  (phoenixd is Apache 2.0, eclair is Apache 2.0). What ACINQ charges for is its role as
  the Lightning service provider behind Phoenix and phoenixd: per-transaction fees and
  inbound-liquidity purchases. Those published rates are recorded below as `fees[]`
  rather than as plans, because they are usage-priced and there is no plan to select.

  plan_count is therefore an honest 0, not a gap. Every rate below is quoted verbatim
  from ACINQ's own published fee table and auto-liquidity page.

  rate: mining fees only (user-chosen feerate)
  param: feerateSatByte

liquidity:
  mechanism: auto-liquidity
  default_request_amount_sat: 2000000
  configurable_with: --auto-liquidity
  service_fee: 1% of the purchased liquidity, plus mining fees, paid upfront
  fee_credit:
    description: >-
      Small incoming payments too small to fund a channel by themselves are paid to the
      LSP and set aside as credit against future fees, instead of being rejected.
    refundable: false
    note: >-
      ACINQ documents the fee credit as explicitly NON-REFUNDABLE and not part of the
      user's balance — it can only pay mining/service fees. Recorded because it is a
      real commercial term a buyer must read before integrating.
    cap_flag: --max-fee-credit
  effective_receive_feerate:
    note: >-
      ACINQ publishes an effective-feerate matrix by mining feerate and liquidity chunk
      size (worst case, receive-only). Quoted verbatim.
    unit: percent of received volume
    table:
    - {mining_feerate_sat_per_byte: 1, at_2m_sat: '1.01%', at_5m_sat: '1.01%', at_10m_sat: '1.00%'}
    - {mining_feerate_sat_per_byte: 10, at_2m_sat: '1.14%', at_5m_sat: '1.05%', at_10m_sat: '1.03%'}
    - {mining_feerate_sat_per_byte: 20, at_2m_sat: '1.27%', at_5m_sat: '1.11%', at_10m_sat: '1.05%'}
    - {mining_feerate_sat_per_byte: 30, at_2m_sat: '1.41%', at_5m_sat: '1.16%', at_10m_sat: '1.08%'}
    - {mining_feerate_sat_per_byte: 50, at_2m_sat: '1.68%', at_5m_sat: '1.27%', at_10m_sat: '1.14%'}
    - {mining_feerate_sat_per_byte: 70, at_2m_sat: '1.95%', at_5m_sat: '1.38%', at_10m_sat: '1.19%'}
  cost_controls:
    flags: [--auto-liquidity, --max-mining-fee, --max-fee-credit]
    api: 'GET /estimateliquidityfees?amountSat= returns {miningFeeSat, serviceFeeSat} before committing'
    note: >-
      A programmable pre-commit cost quote is unusual and worth crediting: an agent can
      price a liquidity operation before triggering it.
