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/semantic-html-pruner)
Output
Returns a 'data' object containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an roi_proof object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing metadata.
Example use cases
Distill docs page for RAG pipeline
“Pull https://docs.openai.com/api-reference and compress it into structured markdown under 1500 tokens so I can stuff it into my retrieval pipeline without blowing my context window.”
Extract tables from financial report
“Fetch https://example.com/annual-report-2024.html and extract it in structured mode so I get all the tables and metadata as JSON — I need the revenue figures.”
Budget-capped research on a news article
“Distill https://www.reuters.com/technology/ai-regulation-2024 using budget mode with a max of 500 tokens, focused on the query 'EU AI Act compliance requirements'.”
Technical details
Endpoint
GEThttps://polymarket-odds.agentdiet.dev/v1/semantic-html-pruner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a webpage but wants to minimize LLM token consumption and cost. Ideal when the raw HTML is too verbose for a context window, when only a specific section of a page is relevant (use budget mode with a query), or when structured extraction of tables and metadata is needed. Prefer over generic scraping tools when token efficiency and ROI reporting are important.
Side effects
- Invalid or unreachable URL returns fetch error
- mode=budget requires query and max_tokens or falls back to defaults
- Raw HTML too large may exceed processing limits
- Paywalled or JS-rendered pages may return incomplete content
- Missing required 'url' parameter returns 400 validation error
- Token budget too small (below 20) rejected by schema validation
