# February 2026

The Market Data PHP SDK reaches v1.0.0, built for traders and developers who want U.S. market data running fast without integration complexity.

-   Last updated February 20, 2026

## PHP SDK UPGRADE

We’re excited to announce the official v1.0.0 release of the [Market Data PHP SDK](/docs/sdk/php), built for independent traders and developers who want U.S. market data running fast without fighting integration complexity.

This release is about reducing setup friction and day-to-day maintenance, so you can spend more time building strategies, scanners, dashboards, and automated workflows.

## Key Features

Bring real-time and historical U.S. stocks and options data into your PHP projects with a single dependency. v1.0.0 includes what you need for serious production use: fast endpoints, reliable behavior under load, clear error reporting, and simple environment-based configuration.

-   **Strict typing and early guardrails**: Built for modern PHP (8.2+), the SDK uses strict typing and typed response models to catch mistakes earlier and make IDE workflows faster with clearer autocomplete and signatures.
-   **Flexible output formats**: Choose the output format that fits your workflow: typed PHP response objects, JSON, or CSV, with no need to redesign your integration.
-   **Predictable error handling with support-ready context**: The SDK provides a clear exception hierarchy (UnauthorizedException, BadStatusCodeError, RequestError, and a shared MarketDataException base), plus request IDs, timestamps, and request URLs to speed up debugging and support tickets.
-   **Built-in reliability**: Automatic retries with exponential backoff handle transient failures, and the SDK checks API status before retrying to avoid unnecessary requests.
-   **Advanced options filtering**: Filter options chains at request time by expiration profile, strike range, delta ranges, spread constraints, open interest, volume, and AM/PM settlement preferences.
-   **Flexible date and cache controls**: Work with practical date/time inputs and control cache freshness with maxage when using cached mode, enabling lower-cost data strategies with explicit freshness boundaries.
-   **Zero-configuration startup**: Get started immediately using MARKETDATA\_TOKEN from environment variables or .env, while still supporting explicit constructor-based configuration for production deployments.
-   **Production-ready architecture**: The SDK includes PSR-3 logging support, robust retries, structured exceptions, and broad test coverage across PHP 8.2, 8.3, 8.4, and 8.5.

**Also this month**: Bug fixes for both Sheets and the API.

-   Fixed a bug that caused new users of Sheets to silently fail when opening the Market Data sidebar due to a permissions issue.
-   Began work on dividend-adjusted candles. Hopefully coming early March!
-   Fixed a bug that caused users to get cached mode even when not requested.
