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/pdf-extract)
Output
Returns a distilled data object containing the page content in the chosen format (markdown, structured tables/metadata, skeleton outline, or BM25-focused excerpt), plus ROI proof metrics (raw token count, distilled token count, tokens saved, compression ratio, LLM cost saved in USD, ROI multiplier), billing details, and cache status.
Example use cases
Cheap LLM web grounding for agent pipelines
“Fetch https://openai.com/pricing and distill it into structured mode so I get clean tables and metadata without wasting tokens on nav bars and footers.”
Budget-capped competitor research snippet
“Pull https://www.anthropic.com/claude and give me only the most relevant 500 tokens about pricing using budget mode with the query 'model pricing tiers'.”
Skeleton outline of a long documentation page
“Distill https://docs.aws.amazon.com/s3/latest/userguide/Welcome.html into skeleton mode so I can see the high-level structure before deciding what sections to read in full.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/pdf-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost. It is especially valuable when working with long documentation pages, competitor sites, or any URL where raw content would exceed context limits. The BM25 budget mode makes it uniquely useful when you have a specific query focus and a hard token ceiling. Prefer it over raw HTML fetching or generic scrapers when compression ratio and cost savings are first-class concerns.
Side effects
- URL is unreachable or returns a non-200 response — endpoint may return an error status
- HTML payload is malformed and cannot be parsed cleanly
- mode=budget used without a query parameter — BM25 scoring may be undefined
- max_tokens ceiling set too low (below 20) — request rejected by schema validation
- Target URL requires JavaScript rendering which the fetcher does not support
- Rate limiting or payment failure via x402 causes the request to be rejected
