X has implemented a substantial price increase for posting links through its application programming interface (API), raising costs from $0.01 to $0.20 per URL posted. The change represents a 1,900 percent increase in pricing for third-party developers and tools that integrate with the platform.

The pricing adjustment affects custom social media software and third-party applications that use X's API to automatically post content containing links to the platform. These tools are commonly used by businesses, content creators, and social media management services to schedule and distribute content across multiple platforms.

The API price change went into effect on Monday, according to reports. The increase applies specifically to posts that include URLs, while other types of API usage may follow different pricing structures.

This pricing adjustment continues a series of changes to X's API access and pricing structure that have occurred since the platform's ownership transition. The company has previously modified its API tiers and pricing models, affecting how third-party developers and applications interact with the platform.

The cost increase may impact social media management tools, automated posting services, and other applications that rely on X's API to share content with embedded links on behalf of users.
