About Codex.io
Codex is an API for enriched blockchain and prediction market data. For tokens, it covers real-time pricing, charts, holders, balances, and aggregated analytics for 80M+ tokens and 700M+ wallets across 80+ networks (EVM chains and Solana), with sub-second freshness, historical USD pricing, and WebSocket and webhook subscriptions.
Codex also provides prediction market data across Polymarket and Kalshi through a single schema. This includes events, markets, traders, holdings, live order books, and trade feeds, along with time-windowed stats and ranking signals (volume, liquidity, open interest, trade count, and unique traders) at 5m through 1w windows that the venue APIs do not expose natively.
Codex is a GraphQL API that most teams query directly, with an optional TypeScript SDK. There is also an MCP server for reading the documentation. Codex offers a free tier (10,000 requests/month), usage-based Growth pricing, and Enterprise plans. Developers use it to build trading platforms.

GPT‑5.3‑Codex‑Spark
GPT-5.3-Codex-Spark is an ultra-fast coding model designed for real-time collaboration inside Codex. Built as a smaller version of GPT-5.3-Codex, it delivers over 1000 tokens per second when served on low-latency Cerebras hardware. The model is optimized for interactive coding tasks, enabling developers to make targeted edits and see results almost instantly. With a 128k context window, Codex-Spark supports substantial project context while maintaining speed. It focuses on lightweight, precise edits and does not automatically run tests unless prompted. Infrastructure upgrades such as persistent WebSocket connections significantly reduce latency across the full request-response pipeline. Released as a research preview for ChatGPT Pro users, Codex-Spark marks the first milestone in OpenAI’s partnership with Cerebras.

Kalshi
Kalshi is a federally regulated derivatives exchange built for quants. Kalshi’s markets are volatile and settle daily, which means even a small edge can be extremely profitable. Trading is fully-cash collateralized, so you can never lose more than you put into a trade, and contracts can be purchased for as little as $0.01.
Kalshi supports trading through its native app (iOS & Android), website, and API. The latter features extensive documentation, open-sources sample code, and live technical support. Getting started with an algorithmic strategy is as easy as `pip3 install kalshi_python`.
The following data is available for free on both the website and API:
* Historical spreads: Use past pricing data to set up back-tests within minutes.
* Low-latency broadcasts: Receive live updates of market price movements and trade executions.
* Economic projections: Build strategies using Kalshi’s proprietary forecasting tools.

DeskBot
DeskBot is a locally run desktop trading terminal for short-duration prediction markets. It trades Kalshi's 15-minute up-or-down contracts across cryptocurrency, metals, energy and currency markets, evaluating potential entries against market prices, time to settlement and rules set by the user. Its dashboard records the rationale for trades and skipped opportunities, while live price feeds come from Coinbase, Kraken and Pyth. Users can begin in simulated paper mode, choose markets and trade direction, and set stake, position and daily-loss limits before enabling live trading. The app also includes a Polymarket section alongside Kalshi for 15-minute crypto markets and cross-checking picks. DeskBot connects to the user's own trading accounts and API keys; funds remain in those accounts. It runs on Mac and Windows computers that stay on while the software operates. Trading involves risk, and the software does not guarantee returns.
