## What it does

Arbitron operates as an HTTP endpoint delivering read-only market statistics for crypto perpetual contracts. It connects AI assistants to tracked exchanges, surfacing active funding rates, venue price discrepancies, and new listing schedules.

The server provides nine distinct tools. Models can look up ticker symbols with `arbitron_search_coins`, fetch current or historical rates via `arbitron_get_funding_rates` and `arbitron_get_funding_history`, or evaluate venue spreads and backtests with `arbitron_get_spreads` and `arbitron_get_spread_backtest`.

The free Demo tier lags by 15 minutes, caps output at 50 records per page, and cuts off historical queries. Live calculations and historical lookups require a paid API key.
