# ABP Bookmaker Capability Matrix

> All 32 bookmakers supported by ABP, grouped by type, with slugs and capability notes — sportsbooks, betting exchanges, prediction markets, and punter platforms.

<Info>
  ABP integrates **32 bookmakers** behind one API. Identify each by its **slug** (e.g. `pinnacle`, `betfair-ex`, `polymarket`). Call `GET /bookmakers` for the live list plus each bookmaker's default stake limits. Your API key may be scoped to a subset — see [Authentication](/abp-api/authentication).

## How to read this page

* **Slug** — the string you pass in account creation, `bookmakers` filters, and order routing.
* **Type** — Sportsbook, Exchange, Prediction market, or Punter platform. Type affects fill behaviour.
* **Sweep** — whether the venue fills a partial-stake order by sweeping its order book in a single shot (see [Order Placement → exchange sweep](/abp-api/order-placement)). Non-sweep venues are filled by ABP's multi-pass weighted-average logic instead.

## Traditional sportsbooks

Single-price venues. ABP places one or more bets against the quoted line and applies the [limit cascade](/abp-api/currency#stake-limit-cascade).

## Betting exchanges

Order-book venues. ABP places against available liquidity.

| Bookmaker          | Slug           | Sweep |
| ------------------ | -------------- | :---: |
| Betfair Exchange   | `betfair-ex`   |   ✅   |
| Smarkets           | `smarkets`     |   —   |
| Limitless Exchange | `limitless-ex` |   —   |
| Matchbook          | `matchbook`    |   —   |

## Prediction markets

Binary/outcome markets, mostly sweep-capable — the venue fills against its book in one shot at your `orderPrice` floor.

| Bookmaker     | Slug            | Sweep |
| ------------- | --------------- | :---: |
| Polymarket    | `polymarket`    |   ✅   |
| Polymarket US | `polymarket.us` |   ✅   |
| Kalshi        | `kalshi`        |   ✅   |
| Predict.fun   | `predict.fun`   |   ✅   |
| ProphetX      | `prophetx`      |   —   |
| SX Bet        | `sx.bet`        |   ✅   |
| Vertex        | `vertex`        |   —   |
| 4casters      | `4casters`      |   ✅   |
| Novig         | `novig.us`      |   ✅   |

## Punter platforms

| Bookmaker   | Slug          | Sweep |
| ----------- | ------------- | :---: |
| Punter.io   | `punter.io`   |   —   |
| Punter.io++ | `punter.io++` |   —   |

## Live betslip fetching

Most bookmakers' odds and limits arrive through [OddsPapi v5](https://docs.oddspapi.io/). A few venues (for example `singbet`) don't expose limits through OddsPapi, so ABP fetches them live from the bookmaker API whenever a subscribed price changes — deduplicated per unique account. This is transparent to you: the `betslip` WebSocket channel and `GET /betslip` behave identically regardless of the source.

## Stake limits

Each bookmaker carries default `minStake` / `maxStake` values, returned by `GET /bookmakers`. These are the *bookmaker* tier of the [limit cascade](/abp-api/currency#stake-limit-cascade) — an account override or a tighter odds limit can supersede them.
