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/spa-markdown-reader)
Output
Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes optional cache hit/miss status and billing details.
Example use cases
Compress docs page for LLM context
“Grab the content at https://docs.openai.com/api-reference and distill it into structured markdown — I need it token-efficient enough to fit in my agent's context window.”
BM25 budget excerpt for research
“Pull https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) and give me only the most relevant 300 tokens about 'attention mechanism' using budget mode.”
Extract structured tables from a report
“Distill https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=TSLA into structured mode so I get the tables and metadata as clean JSON without all the surrounding noise.”

Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/spa-markdown-reader?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 — especially useful for long documentation pages, news articles, or SEC filings. Prefer it over raw fetch when you need BM25-ranked relevance filtering around a specific query, structured JSON extraction of tables, or a skeleton outline. It is particularly well-suited for agentic pipelines where context window cost and compression ratio matter.
Side effects
- Invalid or unreachable URL returns an error status
- HTML fetch timeout for slow or JS-heavy SPAs
- Token budget too low (below 20) causes validation error
- BM25 query missing when mode=budget may return unfiltered content
- Raw HTML too large may exceed processing limits
- Paywalled or bot-protected pages may return empty or partial content
