The full answer each AI engine gives to a prompt, with its sources
2–64 credits / engine, by modelDetails
The full answer Perplexity, ChatGPT, Claude, Gemini and Grok each give to PROMPT, with the sources each one cited, in one normalized shape. No brand check: use check_visibility for that. Useful to see how engines frame a topic before writing content, or to read what they say about a competitor. Credits depend on the model (see `models`); timeouts are free. Takes up to 30 s (45 s with a premium model).
The question to ask, e.g. 'which table tennis blade suits a beginner?'
Subset of engines. Default: all five. Each engine that answers costs its model's credits (see `models`).
