How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/spa-markdown-reader)
Output
Returns a status field, distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), ROI proof metrics (raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, ROI multiplier), optional cache hit/miss info, and billing details.
Example use cases
LLM-ready documentation distillation
“Pull the React documentation at https://react.dev/reference/react and convert it to clean markdown so I can feed it into my LLM without wasting tokens on nav menus and footers.”
Focused research with token budget
“Fetch https://openai.com/research/gpt-4 and give me only the sections most relevant to 'safety benchmarks' — use budget mode, cap it at 1500 tokens.”
Structured data extraction from HTML
“I have a raw HTML blob from a product page — can you distill it in structured mode so I get the tables and metadata as clean JSON instead of raw markup?”

Endpoint
POSThttps://x402broker.com/v1/spa-markdown-reader?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert live web pages or raw HTML into LLM-consumable content with controlled token budgets. It is especially valuable when working with documentation sites, long-form articles, or SPA-rendered pages where you want BM25 query-focused excerpts rather than full page dumps. Prefer it over generic scrapers when ROI/token-savings tracking matters or when you need structured JSON output from HTML tables.
Side effects
- URL unreachable or returns non-200 — fetch failure with error status
- HTML too short or empty — may return minimal or empty distillation
- Token budget too low (max_tokens < 20) — validation error
- Invalid mode enum value — request rejected with schema error
- SPA JavaScript-heavy pages may not fully render — incomplete content extraction
- Payment failure via x402 — 402 response requiring payment to proceed
