How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://company-enrich.agentdiet.dev/v1/prompt-compress)
Output
Returns a distilled version of the webpage content in the requested mode (markdown, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and optional cache hit/miss status and billing details.
Example use cases
Compressing docs into LLM context
“Grab https://docs.openai.com/api-reference and distill it into structured mode so I can fit the key tables and metadata into my agent's context without blowing the token limit.”
BM25 focused research excerpt
“Fetch https://www.sec.gov/cgi-bin/browse-edgar and extract only the parts relevant to 'annual report 10-K filings' using budget mode with a max of 300 tokens.”
Skeleton outline of a long article
“Take this URL https://en.wikipedia.org/wiki/Large_language_model and give me a skeleton outline of the page structure so I can decide which sections to dive into.”

Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/prompt-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to inject web page content into an LLM prompt but must control token usage — especially when the raw page would exceed context limits or inflate LLM costs. It is ideal for agent pipelines that fetch documentation, articles, or structured web data and need BM25-ranked, budget-constrained, or outline-only excerpts rather than full HTML. Prefer it over generic scraping endpoints when token ROI and cost savings need to be measurable and auditable.
Side effects
- Invalid or unreachable URL returns an error status
- Mode set to 'budget' without providing 'query' may return unfiltered or degraded output
- max_tokens set below minimum of 20 causes validation failure
- Raw HTML too large may cause timeout or truncation
- URL behind authentication walls cannot be fetched
- Malformed HTML may produce low-quality distillation output
