Last year, Elon Musk curtailed free API access and released new paid tiers with the basic level starting at $100 per month. The company released a $5,000 per month Pro tier with higher limits later in the year.

However, there was no way for developers to fetch more tweets if they hit the limit for the month. They either had to wait it out or upgrade to a costlier tier.

With the new top-up launch, the social network said that there are also limits to the number of upgrades developers can purchase. Developers with the basic tier are capped at 10 top-ups and developers with the pro tier are capped at five top-ups per month.

X’s API changes impacted the third-party developer ecosystem massively and many tools such as Tracy Chou’s Block Party have pivoted to concentrate on other social platforms.

The company’s alterations to its API rules also impacted researchers and their ability to study the platform’s data. However, the company had to open up access to researchers in the EU because of the bloc’s Digital Services Act (DSA) rules.
