How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://alpha-stream.agentdiet.dev/v1/webpage-distiller)
Output
Returns a JSON object with a 'data' field containing the distilled content (markdown text, structured JSON tables, skeleton outline, or BM25-focused excerpt depending on mode), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes optional cache hit/miss metadata and billing details.
Example use cases
Token-budget research for LLM pipeline
“Fetch https://openai.com/research/gpt-4 and distill it in budget mode with the query 'multimodal capabilities', capping the output at 300 tokens so I don't blow my context window.”
Structured data extraction from docs page
“Pull the pricing page at https://vercel.com/pricing and distill it in structured mode so I get clean JSON tables of the plans and features.”
Skeleton outline of a long article
“Take this raw HTML I'm pasting and give me a skeleton outline of its sections and headings so I can navigate it quickly without reading the whole thing.”

Choose this endpoint when you need to reduce the token footprint of web content before passing it to an LLM, especially when you want fine-grained control over output format (markdown, structured, skeleton, or BM25 budget excerpt) and need ROI proof of token savings. It is superior to generic scraping APIs when token budget management and LLM cost reduction are priorities, and uniquely useful when you need BM25-ranked excerpts relevant to a specific query rather than full-page content.
Side effects
- URL is unreachable or returns a non-200 HTTP status — distillation fails with an error status
- Raw HTML is malformed or empty — parser may return minimal or empty output
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query not provided when mode=budget — may return unfiltered or error response
- Payment not attached or insufficient — x402 payment required error
- Rate limiting or timeout on slow/large target pages — latency spike or timeout failure
