description: TigerBeetle is an open-source (Apache 2.0) distributed financial accounting and transactions database, purpose-built
  for high-throughput, mission-critical double-entry bookkeeping and online transaction processing (OLTP). It is NOT an HTTP/REST
  API and ships no OpenAPI - the database is accessed over a custom binary wire protocol on TCP (default port 3000) via official
  client libraries for .NET, Go, Java, Node.js, Python, Ruby, and Rust. The "API" is the set of client operations - create_accounts,
  create_transfers, lookup_accounts, lookup_transfers, get_account_transfers, get_account_balances, query_accounts, and query_transfers
  - that use fixed-size, cache-line-aligned structs for zero-deserialization performance. TigerBeetle is self-hostable; a
  fully managed service is also offered to select enterprise partners via sales@tigerbeetle.com.

  description: Client-library operations for managing 128-byte double-entry accounts - create_accounts (establish immutable
    accounts on a ledger with debit/credit constraint flags), lookup_accounts (fetch accounts by 128-bit id), and query_accounts
    (filter accounts by ledger, code, and user_data). Accounts carry pending and posted debit/credit balances. These are binary
    wire-protocol operations invoked through the official clients, not HTTP endpoints; there is no REST baseURL or OpenAPI.

    transfers, and timeouts), lookup_transfers (fetch by 128-bit id), and query_transfers (filter by ledger, code, and user_data).
    Delivered over the binary TCP wire protocol via the official clients - no REST endpoints, no OpenAPI.

  description: The get_account_balances operation returns the historical balances of an account over time (for accounts created
    with the history flag), each a point-in-time AccountBalance record of pending and posted debits and credits. A binary
    wire-protocol operation invoked through the official client libraries, not an HTTP endpoint.

  description: Query surface for retrieving the transfers and balances tied to a single account. The get_account_transfers
    operation takes an AccountFilter (account_id, timestamp range, limit, direction, and flags) to page through an account's
    transfers, and the same filter drives get_account_balances. QueryFilter powers the broader query_accounts / query_transfers
    searches. Binary wire-protocol operations via the official clients - no REST, no OpenAPI.
