How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/context-compress)

Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-scored excerpt depending on mode), an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd, plus optional cache metadata (HIT/MISS, latency_ms) and billing info (fee_charged_usd).

Example use cases

Token-budget research before LLM inference

“Fetch https://openai.com/blog/gpt-4o and distill it in budget mode focused on the query 'multimodal capabilities', keeping it under 300 tokens so I can include it in my next prompt without blowing my context window.”

Structured extraction from a product page

“Take this raw HTML from our competitor's pricing page and distill it into structured tables and metadata — I want clean JSON I can compare against our own pricing.”

Skeleton outline for a long documentation page

“Grab https://docs.anthropic.com/claude/reference/getting-started-with-the-api and give me a skeleton outline of the page structure so I can quickly navigate to the section about rate limits.”

When to prefer

Choose this endpoint when you need to shrink web content to fit within an LLM context window before inference, especially when you have a specific topic focus (use budget+query mode for BM25 relevance filtering) or need a strict token ceiling. It is superior to raw scraping when token cost matters, and better than generic summarizers when you need structured output modes (tables, skeleton, Markdown) with transparent ROI metrics showing exactly how many tokens and dollars were saved.

Side effects

URL is unreachable or returns non-200 — fetch error with status detail
HTML payload is empty or malformed — distillation returns minimal or empty data field
max_tokens is below the minimum of 20 — validation error
mode=budget used without a query — BM25 scoring may return generic top passage
Page is JavaScript-rendered and content is not in static HTML — distillation may miss dynamic content
x402 payment fails or agent_id is invalid — 402 Payment Required response
