Crawl4AIWeb & SEO DataSEO/AEO

Answer a question from the web, prose or JSON

crawl4ai.web.answer

Answers a question or a whole agent prompt (up to 4,000 characters) from the web's current top results, with the pages it drew on. Ask for JSON in the question, or pass a JSON Schema, and the answer is JSON of that shape. answer.source says whether the text is Google's own answer (google_ai_mode, google_ai_overview) or written from the pages (crawl4ai). answered is false, and free, when the pages hold no answer. Experimental: fields may be added.
