Endpoint
GEThttps://api.aiskills402.com/v1/skills/summarize/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you want to add a faithful summarization capability to an AI agent and need a ready-made, tested skill file in Agent Skills format rather than writing your own prompting instructions. Particularly useful when accuracy of facts, numbers, names, and dates in the summary is critical and hallucination must be avoided. Prefer over building custom summarization prompts when you want a one-time purchase with ongoing updates.
