Supported Venues

PMXT currently supports the following venue targets. The wire key is the value you pass in the URL — e.g. POST /api/polymarket/fetchMarkets or new pmxt.Polymarket({}) from the SDKs.

Venue	Wire Key	Pass-Through Base
Polymarket	`polymarket`	`POST /api/polymarket/:method`
Kalshi	`kalshi`	`POST /api/kalshi/:method`
Kalshi (Demo)	`kalshi-demo`	`POST /api/kalshi-demo/:method`
Limitless	`limitless`	`POST /api/limitless/:method`
Probable	`probable`	`POST /api/probable/:method`
Baozi	`baozi`	`POST /api/baozi/:method`
Myriad	`myriad`	`POST /api/myriad/:method`
Opinion	`opinion`	`POST /api/opinion/:method`
Metaculus	`metaculus`	`POST /api/metaculus/:method`
Smarkets	`smarkets`	`POST /api/smarkets/:method`
Polymarket US	`polymarket_us`	`POST /api/polymarket_us/:method`
Gemini Titan	`gemini-titan`	`POST /api/gemini-titan/:method`
Hyperliquid	`hyperliquid`	`POST /api/hyperliquid/:method`
SuiBets	`suibets`	`POST /api/suibets/:method`
Rain	`rain`	`POST /api/rain/:method`
Hunch	`hunch`	`POST /api/hunch/:method`

This list is regenerated automatically from the ExchangeParam enum in pmxt-core’s OpenAPI spec on every pmxt-core upgrade. If a venue is missing here, it’s not yet wired through pmxt-core.

Feature support

Not every venue supports every method. Broadly:

Catalog reads (fetchMarkets, fetchEvents, fetchMarket, fetchEvent) — supported on every venue that the catalog ingests.
Live reads (fetchOrderBook, fetchOHLCV, fetchTrades) — supported where the venue exposes the data.
Writes (createOrder, cancelOrder, fetchBalance, fetchPositions) — supported where the venue has a trading API.

See the API Reference for the per-method matrix (inferred from the OpenAPI operationIds).
