# Fill realism (read)

`GET /api/bot/v1/realism`

## Request

- Base URL: `https://marginpad.io`
- URL: `https://marginpad.io/api/bot/v1/realism`
- Auth: none declared

Two deliberate simplifications in the engine, made optional: a market order fills at the live price with no slippage, and maintenance margin is a flat 0.5%. Both are off by default. Returns your setting, the published maintenance-margin rate of every venue, the whole size-tier ladder and what each switch does. Requires a key.

## Response `200`

{ realism:{slippage, margin_tiers, margin_venue}, defaults, effective, margin_venues, tiers, explain, applies_to }
