How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://polymarket-odds.agentdiet.dev/v1/context-trimmer)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD, plus optional cache metadata and billing details.
Example use cases
Reduce docs page for LLM context
“Pull the Stripe API docs at https://stripe.com/docs/api and distill them into structured tables with under 3000 tokens so I can fit them in my prompt window.”
BM25 focused excerpt for research
“Fetch https://en.wikipedia.org/wiki/Large_language_model and give me only the sections most relevant to 'transformer architecture', staying under 1500 tokens using budget mode.”
Skeleton outline of a long article
“Get the article at https://www.wired.com/story/openai-gpt4 and return a skeleton outline of its structure so I can quickly see what sections it covers.”

Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fit web content into a limited LLM context window, want to reduce token costs before processing a webpage, or need structured/skeleton extraction from arbitrary URLs. Particularly valuable when you have a specific focus query (BM25 budget mode) and need only the most relevant content from a long page. Prefer it over generic scrapers when token efficiency and LLM cost reduction are priorities.
Side effects
- Invalid or unreachable URL returns an error status
- URL timeout if the target page is slow to respond
- max_tokens set below minimum of 20 returns validation error
- query parameter ignored if mode is not 'budget'
- Rate limiting or payment failure via x402 if balance is insufficient
- Raw HTML too large may exceed processing limits
