How this service works
Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://serp-extract.agentdiet.dev/v1/context-trimmer)
Output
Returns a distilled version of the webpage in the requested mode (markdown, structured JSON, skeleton outline, or BM25 budget excerpt), along with an roi_proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and an ROI multiplier. Also includes cache hit/miss status and billing details.
Example use cases
Trimming docs page for LLM grounding
“Fetch https://docs.openai.com/guides/function-calling and distill it into clean markdown under 2000 tokens so I can include it in my system prompt without exceeding my context limit.”
Focused BM25 extraction from a news article
“I need the most relevant sections from https://techcrunch.com/2025/05/10/ai-agent-funding — use budget mode with a max of 800 tokens and focus the BM25 query on 'agent infrastructure investment'.”
Structured data extraction from a product page
“Pull https://www.anthropic.com/pricing and return a structured JSON table of all the pricing tiers and token costs — I need clean data I can compare programmatically.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pass web page content to an LLM but want to minimize token usage and cost — especially when working with long documentation pages, news articles, or product pages. The BM25 budget mode is uniquely useful when you have a specific query focus and a hard token ceiling. Prefer this over general-purpose scrapers when compression ratio and token savings are first-class concerns, or when you want structured JSON tables extracted rather than raw HTML.
Side effects
- Invalid or unreachable URL returns an error status
- max_tokens below minimum of 20 is rejected
- mode=budget without a query may return unfiltered budget excerpt
- Raw HTML too large may time out or be truncated
- Paywalled or JavaScript-rendered pages may return incomplete content
- Missing required url parameter returns validation error
