How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/context-trimmer)
Output
Returns a distilled version of the page in the requested mode (markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved, and optionally billing and cache status.
Example use cases
Token-budget research digest
“Fetch https://openai.com/research/gpt-4 and distill it into budget mode with a max of 1500 tokens, focusing on the query 'model capabilities and benchmarks' — I need it tight enough to fit in my agent's context window.”
Structured data extraction from docs
“Distill https://docs.stripe.com/api in structured mode so I get the tables and metadata pulled out cleanly as JSON — I'm building an agent that needs to reference Stripe's API fields.”
Quick skeleton outline of a news article
“Give me a skeleton outline of https://techcrunch.com/2024/05/01/ai-funding-roundup so I can quickly see the document structure and headings without reading the whole thing.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed web page content into an LLM context window and must control token usage — especially when working with documentation, news articles, or reference pages that are verbose. It is particularly valuable when you have a strict token budget and a specific topic to focus on (BM25 budget mode), or when you need structured metadata/tables extracted from a page rather than raw prose. Prefer this over generic scrapers when ROI proof and token savings metrics matter to your pipeline.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error status
- URL yields no extractable text content (e.g. pure JavaScript SPA without SSR) — distilled output may be empty or minimal
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Raw HTML input is malformed or extremely large — may time out or produce degraded output
- Payment not provided or insufficient — HTTP 402 response blocking access
