Get a free API key with email to access 500+ Hugging Face models.
@pengsonal · X
500+ Hugging Face models through a single free API no credit card just an email signup 😳 launched on July 3 as a unified gateway for Hugging Face models one API key one endpoint 500+ models what you get for $0: • 500+ open-source models through an OpenAI-compatible API • no separate API keys for different providers • works with Cursor, Claude Code, Hermes, OpenCode, and anything that supports a custom base URL • email signup only setup takes about 2 minutes: 1. Go to 2. Sign up with your email 3. Generate an API key 4. Set your base URL to 5. Choose any model from the catalog and start building a few things worth knowing: • is a third-party gateway, not an official Hugging Face product • the free tier is rate-limited, but the exact limits haven't been published yet • i wouldn't build production apps that depend entirely on a free aggregator what i like is the simplicity instead

最近一直在体验 @dappOS_com 的 xBubble Coding,这两天顺手做了一个自己一直想要的小工具——AI Meme 热点雷达。 👉 玩 Crypto 的人应该都有同样的感受,真正难的不是获取信息,而是信息太多。 每天都有新的 Meme、新的叙事、新的热点,X、Telegram、社区讨论、KOL 观点不断更新。很多时候,当一个项目真正火起来的时候,市场已经提前反应了。 所以我想做一个工具,把这些分散的信息整合到一起。 它不会告诉你哪个币一定会涨,也不会替你做交易,而是持续监控市场热度变化,整理不同平台的讨论情况,帮助用户更快发现值得关注的新热点,把原本需要花大量时间收集的信息,用更直观的方式展示出来。 整个开发过程也让我挺意外。 我没有写一行代码,只是把需求描述给 xBubble,不到十分钟,一个可以直接访问的网站就已经搭建完成。从页面生成、功能实现到部署上线,整个流程几乎都是自动完成的。 以前很多 AI Coding 工具解决的是"写代码"的问题,但真正做一个产品,后面还有服务器、部署、域名、接口等一系列工作。 而 xBubble 更像是在帮你完成整个产品交付,而不仅仅是生成代码。 体验下来,我最大的感受是,现在很多个人开发者、内容创作者,甚至没有技术背景的人,都有机会把自己的想法快速做出来,再去验证有没有用户,而不是因为开发门槛太高,让一个不错的创意停留在想法阶段。 AI 正在不断降低产品创造的门槛,而真正重要的,或许已经不是谁代码写得更快,而是谁能够更快发现需求,把想法变成真正可以使用的产品。
