How this service works
Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://serp-extract.agentdiet.dev/v1/clean-html)
Output
Returns a data object containing distilled content in the requested format (Markdown, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt), plus an roi_proof block showing 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
Distill docs page for agent context
“Fetch https://docs.openai.com/api-reference and compress it into markdown under 800 tokens so I can inject it into my agent's context window without blowing my budget.”
Extract structured pricing table from SaaS site
“Pull the page at https://linear.app/pricing and distill it in structured mode so I get the pricing tiers and feature tables as clean JSON.”
Focused BM25 snippet from news article
“Go to https://techcrunch.com/2024/05/01/openai-update/ and extract only the parts most relevant to 'GPT-5 release date' using budget mode with a max of 300 tokens.”

Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/clean-html?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read web content but must stay within a token budget — especially useful when injecting page content into LLM context windows where cost and length matter. Prefer this over raw fetch/scrape tools when you need BM25-focused relevance trimming, structured extraction, or proven compression ROI metrics. Ideal for agentic pipelines that process many pages and need to minimize LLM token spend.
Side effects
- Invalid or unreachable URL returns an error status
- HTML fetch timeout for slow or large pages
- Token budget too low (below 20) triggers validation error
- Unsupported mode value returns enum validation error
- Empty or malformed HTML input causes distillation failure
- Payment not provided results in HTTP 402 payment required
