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/spa-markdown-reader)
Output
Returns a JSON object with a 'data' field containing distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or focused BM25 excerpt depending on mode), plus ROI proof metrics showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache hit/miss status and billing details.
Example use cases
Stripe docs lookup for agent
“Pull https://stripe.com/docs/api/payment_intents and distill it into structured mode so I can see the tables and metadata without all the extra HTML noise.”
Token-budget research digest
“Fetch https://openai.com/research/gpt-4 and give me a BM25-focused excerpt about 'multimodal capabilities' capped at 500 tokens — I need to stay within my context window.”
SPA page content extraction
“Distill https://github.com/anthropics/anthropic-sdk-python into markdown so my agent can read the README and code structure without fetching gigabytes of raw HTML.”

Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read live web content but must stay within a strict token budget, or when the target page is a JavaScript-rendered SPA that raw HTTP fetchers cannot parse. It is especially valuable when LLM cost savings need to be quantified (ROI proof) or when you need BM25-focused excerpts rather than full-page dumps. Prefer over generic scrapers when you need structured JSON tables or skeleton outlines from web pages.
Side effects
- Invalid or unreachable URL returns an error status
- JavaScript-heavy SPAs may time out if rendering takes too long
- mode=budget without a query or max_tokens may return unfiltered output
- Raw HTML input exceeds payload size limits
- Token budget too small (below 20) rejected by schema validation
- Rate limiting or payment failures via x402 result in 402 response
