Cancel a working order by ID. Idempotent at the Luno API level: cancelling an already-cancelled or fully-filled order returns the current state without error. Use after list_orders to remove a specific working order. Write operation: requires the --allow-write-operations flag or ALLOW_WRITE_OPERATIONS=true.

Instantly convert funds between two currency accounts on the authenticated profile via the Luno broker (e.g. ZAR to ZARU). The conversion is final and applies the broker quote at execution time. Pass idempotency_key to make retries safe; omitting it generates a fresh UUID per call, so retries on network error may double-convert. Write operation: requires the --allow-write-operations flag or ALLOW_WRITE_OPERATIONS=true.

Place a new GTC limit order on Luno. The order rests on the book and may fill partially, fully, or not at all; this tool does not wait for or report fills - use list_orders to inspect state, or cancel_order to withdraw a working order. Not idempotent: repeated calls create duplicate orders. Prefer get_markets_info first to validate the pair's tick size and minimum volume. Write operation: requires the --allow-write-operations flag or ALLOW_WRITE_OPERATIONS=true.

Return balances for every account on the authenticated Luno profile, including available, reserved, and unconfirmed amounts per asset. Requires API credentials. Use this to check holdings before placing orders, conversions, or transfers; not for public market data (use get_ticker or get_tickers).

Return OHLCV candlestick data for a trading pair. Each candle contains timestamp (ms), open, high, low, close, and base-currency volume. Public endpoint, no auth required. Use for charts, indicators, or backtesting; not for live order-book state (use get_order_book) or trade-by-trade flow (use list_trades).

List supported Luno markets and their trading parameters: min/max base and counter volume, price/volume tick size, fee tiers, status, and base/counter currency. Public endpoint, no auth required. Use this before placing an order to validate price/volume against the market's tick and minimum constraints; not for live prices (use get_ticker).

Return the top 100 bids and asks for a trading pair, aggregated by price level. Public endpoint, no auth required. Use this to assess available liquidity and likely slippage before sizing an order; use get_ticker for a simple price quote or list_trades for recent execution flow.

Get the latest ticker (last trade price, best bid, best ask, 24h rolling volume) for a single Luno trading pair. Public endpoint, no auth required. Use this for a quick price snapshot of one market; use get_tickers for multiple markets at once, or get_order_book for depth-of-book.

List the latest tickers for all Luno trading pairs, or for a comma-separated subset. Each ticker has last trade price, best bid, best ask, and 24h volume. Public endpoint, no auth required. Use this to survey or compare multiple markets in one call; use get_ticker when you only need a single pair.

Return the full ledger entry for one transaction on the authenticated profile (amount, running balance, description, timestamp). Only finds transactions within the most recent 1000 rows of the account; for older entries, narrow the search with list_transactions first. Requires API credentials.

List orders on the authenticated profile (open by default; recently completed orders may also appear depending on Luno API behaviour), optionally filtered by trading pair. Requires API credentials. Use this to inspect or audit working orders before cancelling them or placing new ones.

List recent public trades for a trading pair, with price, volume, side (BUY/SELL), and timestamp. Public endpoint, no auth required. Use for recent execution flow or tape analysis; not for your own trade history.

List ledger entries for a single account on the authenticated profile, paginated by row ID. min_row is inclusive, max_row is exclusive, and the API caps a single window at 1000 rows. Requires API credentials. Use for reconciliation, exports, or audit trails; iterate by advancing min_row to (last returned row + 1).
