Kalshi Spread and Depth Snapshots (Earliest 50 of the Past 7 Days)

omnial/kalshi-orderbook-snapshots

Given a Kalshi market ticker, returns the earliest 50 order book snapshots from the past seven days, oldest first: each snapshot's time (Unix milliseconds), best Yes bid and best Yes ask (in cents) and total Yes bid and Yes ask depth (in contracts). The snapshots start about seven days before the call, so they show the book as it was a week ago, not now. Individual price levels are not included.

Pricing

Every real charge, itemised. A model that quietly omits one is a slow financial leak, so nothing here is rolled up, and a charge that only applies to some inputs says so rather than being added in.

Prices in this catalog are the provider's own list price, not your bill: Omnial MCP charges provider cost plus a platform markup on top, so what you are charged is higher than the figure shown. For the exact amount a specific call will cost, run omnial_execute with dry_run: true; that number includes the markup and is what we hold while the call runs. It is a quote, not a cap on the charge.

Charge	Rate
Per call Flat, regardless of what comes back	$0.03276

Cost basis: Not recorded
This tool's catalog entry does not record how its final bill is determined, so we will not tell you whether its cost is fixed before the call or reported by the provider afterwards. Either way what is held is a quote rather than a cap: you are charged what the call actually costs, bounded at 2x the quote.
