Tools & capabilities
CCXT tools 32
list_exchangesList every exchange this server supports (built from ccxt.exchanges at runtime), with name, websocket and prediction-market availability. Filter by a name query or by support for a unified method.describe_exchangeOne exchange's supported unified methods, market types, timeframes, required credential fields, sandbox availability and documentation URLs. Per-method detail lives in describe_method.describe_methodSearch unified method names by keyword, or get one method's signature and parameter documentation. With "exchange" it adds that exchange's own docs (including supported params.* keys and links to the exchange API reference), per-market-type feature support, and searches its implicit (exchange-specific) endpoints too. Full ccxt manual: https://docs.ccxt.com/search_marketsSearch and filter the markets of one exchange (by text, base, quote, settle currency, market type), paginated. Use this to resolve unified symbols — there is deliberately no list-all-markets tool. On prediction exchanges use search_events instead.get_tickers24h price tickers for one or more unified symbols on an exchange (outcome handles on prediction exchanges).get_orderbookCurrent order book (bids and asks) for one unified symbol.get_ohlcvHistorical OHLCV candlestick data for a symbol and timeframe. Rows are [timestampMs, open, high, low, close, volume]. Page back with "since"; "params.until" bounds the end.get_tradesRecent public trades for one unified symbol.search_eventsSearch events on a prediction-market exchange (polymarket, kalshi, limitless, myriad, hyperliquid with prediction=true). A scoping filter is required: query, tags, or params.eventId/params.slug. Returns events with their markets and outcome handles — outcome handles are what you pass as the symbol to get_tickers/get_orderbook/create_order on prediction exchanges.call_read_methodEscape hatch covering every unified read method not served by a dedicated tool (fetchFundingRate, fetchLedger, fetchOpenInterest, fetchLiquidations, fetchEvent, fetchSettlements, …). Only fetch*/load* methods are accepted — writes are structurally rejected. Get the signature first with describe_method. Docs: https://docs.ccxt.com/call_implicit_getCall an exchange-specific implicit REST endpoint over HTTP GET, for data the unified API does not cover. Pass the implicit method name in the "method" argument (e.g. "publicGetTickerPrice"); these are exchange-specific — find them with describe_method {"query": ..., "exchange": ...} (its results list the name to pass here). The response is the raw exchange payload. Consult the exchange API reference (describe_exchange .urls.doc) and the ccxt manual: https://docs.ccxt.com/get_safety_statusWhat this server is currently allowed to do: configured accounts (names only — never credentials), enabled capability tiers, caps, sandbox/live environments, journal location, unresolved order intents, and any configuration problems.- +20 more on the listing page
