X API has announced significant pricing adjustments and the launch of a new CLI tool, effective April 20. The Owned Reads fee will be reduced to $0.001 per request, covering 12 common endpoints such as retrieving tweets and bookmarks. However, the standard posting fee will increase from $0.01 to $0.015, with posts containing URLs priced at $0.20. Additionally, follow, like, and quote retweet features will be removed from all self-service tiers. The new CLI tool, featuring integrated SKILL.md support, allows access to the X API via OpenClaw and Hermes. This move aims to lower usage costs while maintaining sustainable operations, as highlighted by Musk in a recent user post reference.
