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/paywall-clean-extract)
Output
Returns a distilled version of the requested webpage in the chosen format (Markdown, structured JSON, skeleton outline, or BM25-ranked budget excerpt), along with an roi_proof object showing raw vs. distilled token counts, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and an ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
Example use cases
LLM context window cost reduction
“Grab the content from https://openai.com/blog/gpt-4o and distill it into markdown mode so I can feed it to my agent without wasting tokens — show me how much I saved.”
Focused research on specific topic
“Fetch https://docs.aws.amazon.com/lambda/latest/dg/welcome.html in budget mode with the query 'cold start latency' and cap it at 300 tokens so I only get the most relevant section.”
Structured data extraction from webpage
“Pull the page at https://en.wikipedia.org/wiki/Large_language_model and give me the content in structured mode so I get the tables and metadata as clean JSON rather than raw HTML.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/paywall-clean-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to ingest web content but must stay within LLM context or cost limits — especially when you need BM25-ranked focused excerpts (mode=budget), clean Markdown distillation, or structured JSON extraction from arbitrary URLs. Prefer it over generic scrapers when token economy and ROI tracking matter, or when you need to pass web content downstream to an LLM and want compression metrics to justify the fetch cost.
Side effects
- Invalid or unreachable URL returns an error status
- URL behind a hard paywall that cannot be fetched returns empty or partial content
- Exceeding the x402 payment budget or missing payment headers results in 402 Payment Required
- mode=budget without a query parameter may return unfiltered or degraded output
- Very large pages may exceed processing limits or produce high token counts before compression
- HTML parameter conflicts with URL fetch if both are provided simultaneously
