response"],"whenToPreferThis":"Choose this endpoint when you need to feed web content into an LLM but want to minimize token usage and cost — especially when working with long documentation pages, news articles, or raw HTML that would otherwise overflow a context window. It's particularly valuable when you have a strict token budget (mode=budget with max_tokens) or need BM25-focused relevance extraction around a specific query. Prefer it over raw fetch-and-pass when LLM cost or context length is a concern.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-21T07:23:49.057Z","isFirstParty":false,"canonicalSlug":"onchain-risk-agentdiet-dev-web-url-context-compressor-05c0c074"}
