How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/spa-markdown-reader)
Output
Returns a status field, distilled content object (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), ROI proof metrics (raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, llm_cost_saved_usd, roi_multiplier), optional cache status (HIT/MISS with latency), and billing details.
Example use cases
Token-budget research from live docs
“Pull the content from https://docs.openai.com/api-reference and distill it in budget mode with the query 'rate limits and pricing', capped at 800 tokens — I want only the relevant bits for my agent.”
Structured data extraction from product page
“Take this URL https://example-shop.com/product/123 and distill it in structured mode so I get the product tables, pricing, and metadata as JSON rather than raw HTML.”
Inline HTML summarization for pipeline
“I have this raw HTML blob from a scraped article — distill it into clean markdown so my LLM pipeline can read it without wasting tokens on nav bars and ads.”

Endpoint
POSThttps://whale-momentum.agentdiet.dev/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to read web pages or raw HTML but must stay within strict token budgets, or when you need BM25-ranked relevance filtering to extract only the content pertinent to a specific query. It is especially useful for LLM pipelines where token cost matters, for SPA-heavy sites that need server-side distillation, and when you want structured JSON tables or a skeleton outline rather than raw HTML. Prefer it over generic scrapers when compression ratio and ROI proof are important for your agent's cost accounting.
Side effects
- URL unreachable or returns non-200 — fetch failure with error status
- HTML too large and no token budget set — may exceed context limits
- BM25 query missing when mode=budget — query field required for budget mode
- Invalid URL format — validation error on url field
- SPA with heavy JavaScript rendering may not fully execute — partial content returned
- Token budget too low (below 20) — rejected by schema validation
