How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://token-intel.agentdiet.dev/v1/context-trimmer)
Output
Returns a JSON object containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), plus roi_proof metrics showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
Example use cases
Token-efficient research briefing
“Fetch https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and distill it into clean markdown, keeping it under 800 tokens and focused on the query 'attention mechanism' — I want only the relevant bits for my agent's context.”
Structured data extraction from landing page
“Take this URL https://openai.com/pricing and distill it in structured mode so I get tables and metadata about their pricing tiers — I need it in a format my agent can parse easily.”
Skeleton outline for long-form article
“Distill https://example.com/very-long-blog-post into a skeleton outline so I can see the section headers and structure without loading thousands of tokens into my prompt.”

Endpoint
GEThttps://token-intel.agentdiet.dev/v1/context-trimmer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed web content to an LLM but want to minimize token consumption and cost — particularly when you have a specific query focus (BM25 mode) or a hard token budget ceiling. Prefer over raw web scraping when you need clean markdown or structured output ready for agent consumption. Especially useful in agentic pipelines where context window size is a binding constraint.
Side effects
- Invalid or unreachable URL returns an error status
- Token budget too low (max_tokens < 20) causes validation failure
- BM25 query provided without mode=budget may be ignored
- Raw HTML too large may cause timeout or truncation
- Payment required (HTTP 402) if x402 credentials are missing or invalid
- builtin:// scheme only valid for whitelisted built-in document sets
