Tools of Aperiodic Market Data
	Description		Read-only	Idempotent	Open world
`describe_dataset`Field definitions, intervals, exchanges with their start dates, the plan needed and the free preview window for one dataset.	Field definitions, intervals, exchanges with their start dates, the plan needed and the free preview window for one dataset.	No	Yes	Yes	No
`fetch`The full text of one search result: a dataset with all its fields, a category, or the plans guide.	The full text of one search result: a dataset with all its fields, a category, or the plans guide.	No	Yes	Yes	No
`find_symbols`Symbol ids on one exchange matching every word of the query, at most 50: crypto and RWA perpetuals alike. Ids look like "perpetual-BTC-USDT:USDT", "perpetual-TSLA-USDT:USDT" for a tokenized stock on Binance, or "perpetual-XYZ:TSLA-USDC:USDC" for a Hyperliquid HIP-3 market (dex before the colon). Matching is on the id, so search by ticker (e.g. "TSLA"), not by company name. The free preview symbol is perpetual-BTC-USDT:USDT on binance-futures.

`get_data`A handle to one slice of a dataset, not the data: signed Parquet URLs (valid one hour), schema, row counts, per-column min/max/nulls from the Parquet footers, 5 sample rows and a Polars snippet. Load the files in your own code; never paste them into the conversation. Without code, use summarize. Every argument but dataset defaults to the free preview, which needs no API key.

`list_datasets`Every Aperiodic dataset, metrics and raw: id, category, the plan that unlocks it, a one-line description, field count, and whether this caller gets full access or the free preview.

`live_feed`How your own code connects to the real-time WebSocket feed of metrics datasets (raw data is not streamed): its URL, the subscribe frame for a dataset, exchange, interval and symbols, your plan's limits and a Python client. Never the stream itself, which your code consumes outside MCP. The stream authenticates with an API key in X-API-KEY, not an MCP OAuth sign-in. With no dataset, lists what streams and which plans include it.

`summarize`Statistics worked out on our side, for when you can't run code: per-column count, mean, std, quantiles and range ("stats"), a correlation matrix ("correlation"), or the series resampled to at most 500 points ("resample"). Same slice arguments and plan rules as get_data. Decodes only the columns you name (up to 12, numeric; default the first 6).
