can compare tiers without burning tokens."},{"title":"Skeleton outline of a long article","prompt":"Grab the article at https://www.nytimes.com/2024/05/01/technology/ai-agents.html and give me just a

cannot be applied","Payment not provided for paid endpoint — HTTP 402 response requiring x402 payment","URL parameter missing — required field, returns validation error"],"whenToPreferThis":"Choose this endpoint when you need to fit external web content into a constrained LLM context window efficiently, especially when token cost is a concern. It is ideal for agentic pipelines that must read documentation, articles, or data pages before reasoning, where raw HTML would be too large. Prefer budget mode with a query when you want semantically relevant excerpts rather than full-page summaries. It outperforms generic scrapers by returning token-count metadata and compression ROI, making it easy to track prompt efficiency.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-21T12:46:50.836Z","isFirstParty":false,"canonicalSlug":"defi-yield-agentdiet-dev-web-url-prompt-compressor-with-bm25-budget-984f8acf"}
