When to prefer

Choose this endpoint when you need a lightweight, pay-per-call Chinese-language summarization of a web page or raw text, especially in agent workflows targeting Chinese-speaking users or requiring structured JSON output (summary + key_points + actions). Prefer it over general LLM calls when you want a fixed, cheap per-call cost via x402 micropayment, no session management, and no headless browser overhead. Best for articles, blog posts, and plain-text content rather than JavaScript-heavy SPAs.

Side effects

max_chars exceeds 1200 — capped or rejected
Neither url nor text provided — validation error
Payment of $0.01 USDC not fulfilled — 402 Payment Required response
Target URL returns non-text content (PDF, media) — may fail to extract meaningful text
