“这几天各大自媒体都对ideogram2.0吹爆了，我试了一下，这个新的文生图模型质量确实不错，要说媲美midjourney，好像也差不多了。目前ideogram2.0官方是提供api接口的。所以我就基于官方的api弄了一个dify的自定义工具源码，希望对大家有帮助。”
ideogram2.0的api是需要去他们官网注册一个账户，然后绑定支付的卡。请注意，这里我需要提醒你，这个平台不是绑定一个卡就能用它的api了，而是绑定之后，它会从你的卡里先扣除40刀乐。
然后你才能用它的api，我估摸着，它担心你白P不付款吧，哈哈。
好了，玩笑归玩笑，ideogram官方是有api的，开通了api服务之后，你才能设置apikey。其实这个是最重要的。
话不多说，直接放dify工具的源码吧：

仅供参考哈，自行调试调试就行。
光复制上述的代码还不行，你需要在添加这个工具的时候，设置一下接口的apikey，如下所示：
在dify中添加了这个自定义工具之后，在工作流页面就可以使用了。如下所示
好了，至此，就代表整个工具全部可用了。
下面看看我用ideogram2.0画的图吧。ideogram2.0确实有点东西的。
已经可以根据提示词，直接出UI设计图了。
