name: Hedera Mirror Node REST API FinOps
description: >-
  The Hedera Mirror Node REST API is free to use for read-only queries against
  the public mirror node. There are no per-query fees for accessing historical
  data via the REST API. Cost considerations arise when writing transactions to
  the Hedera mainnet (which requires HBAR fees) or when using commercial
  third-party mirror node providers for higher throughput or SLA guarantees.
costs:
  - name: Mirror Node REST API Access
    description: >-
      Accessing the public Hedera-operated Mirror Node REST API is free of
      charge. No account, API key, or payment method is required. The API is
      rate-limited at 50 requests per second per IP address.
    model: free
    unit: N/A
    price: 0.00
    currency: USD
  - name: Hedera Transaction Fees (Write Operations)
    description: >-
      While the Mirror Node REST API is read-only and free, submitting
      transactions to the Hedera network (e.g., token transfers, contract
      calls, consensus message submissions) incurs fees denominated in HBAR.
      Fees are set in USD and converted to HBAR at the time of the transaction.
      These are network-level fees, not API access fees.
    model: per-transaction
    unit: transaction
    currency: HBAR (USD-denominated, converted at time of transaction)

notes:
  - >-
    The public Mirror Node REST API does not require HBAR to use — it is a
    free read-only data service provided by Hedera for ecosystem developers.
  - >-
    HBAR fees only apply when submitting transactions to consensus nodes, not
    when querying historical data via the mirror node.
  - >-
    Organizations running high-volume applications should consider commercial
    mirror node providers to avoid public rate limit constraints.
