How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://defi-yield.agentdiet.dev/v1/html-to-markdown)
Output
Returns a 'data' object containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), alongside an 'roi_proof' block showing raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes cache hit/miss status and billing details.
Example use cases
Compress docs page for LLM context
“Fetch https://stripe.com/docs/api and convert it to markdown using budget mode focused on 'payment intents', keeping it under 3000 tokens so I can pass it directly to my agent without blowing the context window.”
Extract structured tables from financial HTML
“I have this raw HTML from an earnings report — can you distill it in structured mode so I get the tables and metadata as clean JSON instead of a wall of markup?”
Skeleton outline of a long article
“Pull the article at https://hbr.org/2024/01/the-future-of-ai and give me a skeleton outline — just the headings and key structure — so I can quickly see what it covers before deciding whether to read the full thing.”

Endpoint
POSThttps://defi-yield.agentdiet.dev/v1/html-to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed web page content into an LLM but want to minimize token usage and cost. It is especially valuable when the source page is large and you only care about a focused topic (use mode=budget with a BM25 query), or when you need structured tables and metadata extracted from HTML (use mode=structured). Prefer this over raw fetch-and-parse when you want built-in compression metrics and token-savings proof. It is also suitable when you already have raw HTML and want to avoid an extra fetch round-trip.
Side effects
- URL is unreachable or returns non-200 status — endpoint may return an error status
- Raw HTML input is malformed or empty — distillation may produce empty or partial output
- Token budget too small (below 20 tokens) — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Rate limiting or payment failure via x402 — call blocked until payment resolved
- Target page is JavaScript-rendered SPA — fetched HTML may lack meaningful content
