How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://json-repair.agentdiet.dev/v1/context-compress)
Output
Returns a JSON object with a 'data' field containing the distilled content (markdown, structured tables, skeleton, or BM25 excerpt), an 'roi_proof' block showing raw vs. distilled token counts, compression ratio, and estimated LLM cost saved, plus optional cache hit/miss status and billing details.
Example use cases
Summarize docs page for agent context
“Distill the React documentation page at https://react.dev/reference/react/useState into structured markdown so I can fit it in my prompt without blowing my token budget.”
BM25 budget excerpt from long article
“I need just the sections about 'transformer attention mechanisms' from this long ML paper page at https://arxiv.org/abs/1706.03762 — use budget mode with that query and keep it under 300 tokens.”
Extract skeleton outline of competitor landing page
“Give me a skeleton outline of https://openai.com/pricing so I can quickly understand the page structure without pulling in all the content.”
Technical details
Endpoint
GEThttps://json-repair.agentdiet.dev/v1/context-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch and compress a live webpage into agent-friendly tokens while staying within a strict token budget, especially when BM25 query-focused extraction is needed. It is preferable over generic scrapers when you want both compression ratio metrics and structured/markdown output optimized for LLM context windows. Best suited for single-URL distillation with cost-conscious token management.
Side effects
- Invalid or unreachable URL returns an error status
- HTML too large or malformed may produce incomplete distillation
- max_tokens set below minimum (20) returns a validation error
- mode=budget without a query may yield unfiltered results
- Paywalled or bot-blocked pages may return empty or partial content
- Payment failure (x402) if USDC balance is insufficient
