Try the social, prompt, and API widgets. See the source cards and JSON blocks that can be placed inside an article.
Interactive widgets
Choose a social source, copy or edit a prompt, or build a request from a documented contract. Start with a preset, review its fields, then copy the body, complete request JSON, or cURL.
Social sources
A source card keeps the platform’s presentation and opens the original. The player controls above load provider-hosted media on request.
Choose a template, edit the text, then copy it as plain text. Variables such as {{city}} stay visible until you replace them.
API invocation
The builder covers Google Places Text Search, OpenRouter chat, Higgsfield image and video, Apify actor input, and the build’s FILES tool over MCP and Directory REST. The Fields panel explains required inputs, optional values, and how to read the response. Run copied requests from your authorized client with its environment credentials.
