How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://company-enrich.agentdiet.dev/v1/context-compress)
Output
Returns a 'data' object containing the distilled content in the requested mode (markdown text, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt), plus ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
Example use cases
Budget-capped competitor research page
“Fetch https://openai.com/pricing and give me a BM25-focused excerpt about 'API pricing tiers' with a strict ceiling of 500 tokens — I just need the key numbers, not the whole page.”
Structured data extraction from a news article
“Take this URL — https://techcrunch.com/2024/01/15/some-article — and distill it into structured JSON tables and metadata so my agent can process the key facts without reading the full HTML.”
Skeleton outline of documentation page
“Distill https://docs.github.com/en/rest into a skeleton outline mode so I can see the high-level structure of the REST API docs without loading thousands of tokens into my context.”

Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/context-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read web content but must stay within a strict token budget — especially for LLM pipelines where context window cost matters. Prefer over raw fetch tools when you need the output pre-formatted as markdown, structured JSON, or a skeleton outline. The BM25 budget mode is uniquely valuable when you want only the most query-relevant passages from a page, not the full document. Best for single-URL distillation with measurable token savings.
Side effects
- Invalid or unreachable URL returns fetch error
- HTML too large may exceed processing limits
- BM25 budget mode without a query parameter may return unfiltered content
- max_tokens below minimum of 20 rejected with validation error
- Payment failure via x402 returns 402 status blocking the request
- Mode enum value outside allowed set returns parameter validation error
