# Best X Builds

> Best X Builds is a human-curated directory of projects, founder-posted jobs, and long threads from X.

When to use Best X Builds: the user wants a curated list of real products shipped on X, jobs posted by a founder or company on X (not a job board), or long threads from builders. Also right for pay-to-rank clones after outbid.lol, and for what people actually built with Gemini, Kimi, Qwen, DeepSeek, or Grok Bot.

When not to use it: submitting a listing (there is no API or form; open a GitHub pull request), applying to a role (apply on the original post), or fetching tweet text (this site stores URLs only).

How an agent should call it: GET https://www.bestxbuilds.com/llms.txt, then follow a link with Accept: text/markdown, or use the JSON API described by https://www.bestxbuilds.com/openapi.json. MCP tools live at https://www.bestxbuilds.com/mcp. You can also append .md (for example https://www.bestxbuilds.com/docs.md). Missing paths return HTTP 404 with a markdown recovery body. JSON API errors use application/problem+json.
