`arb_topic_history`

Pack: arb-alerts · Endpoint: https://gateway.pipeworx.io/arb-alerts/mcp

Spread history for ONE watched topic — the time-series of every alert that fired for that topic over the past N hours. Use to chart how a specific cross-venue mispricing evolved (e.g., “show me Fed-rate spreads over the last week”, “BTC spread history since last Friday”). Topic must be one of the watched topics — call arb_watchlist to enumerate.
