# Kalshi tools: choose a data, development or weather workflow

By PredictionToolkit · Published 2026-11-03

This selection separates Kalshi itself from software that connects to it and research that helps interpret a contract. Start with the job you need done, then compare the account, data and operating requirements.

## The exchange is the reference point

Kalshi is the venue in this selection. Use its market question, ticker and settlement rules as the reference when another tool displays a price or event. Its Predictions documentation covers event-contract REST and WebSocket access; the separately documented Perps APIs concern another product.

## Choose where the integration runs

PMXT open-source SDK is the code route. Its repository documents a Kalshi client, while self-hosted mode runs pmxt-core locally and uses venue-native credentials where required. This is a development dependency to operate and maintain, rather than a ready-made research dashboard.

PMXT hosted API supplies managed catalog search and a shared interface across supported venues, including Kalshi. Hosted and local operation use different credentials and infrastructure. The documented hosted write path uses PreFundedEscrow custody; do not infer the same custody model from using the same SDK method name. Check support for the particular venue, method and runtime mode.

## Use weather data for the right contract

Wethr adds station observations, model comparison and weather-analysis tools, with explicit Kalshi temperature education and hourly-market links. Match the station, observation period, units and official settlement report to the contract. A forecast or nearby station reading is not itself the final settlement observation.

## A practical route through the selection

-   For a contract's rules or native account access, start with Kalshi.
-   For a coded integration, read the Kalshi API guide before choosing direct access, local PMXT or hosted PMXT.
-   For temperature research, open Wethr with the contract's exact station and date in hand.
-   For a cross-venue comparison, match settlement conditions before interpreting a price gap.

Compare data-service subscriptions and infrastructure costs separately from exchange trading charges. These official sources establish the products' documented scope; account permissions, live execution and provider latency were not tested for this selection.
