How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/web-scrape)
Output
Returns a JSON object with distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), a cache status object (HIT/MISS with latency), billing info, and an ROI proof block showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD.
Example use cases
Token-budget web research for agents
“Grab https://docs.openai.com/api-reference and distill it in budget mode focused on 'function calling', keeping it under 300 tokens so I can feed it to my agent without blowing the context window.”
Structured data extraction from landing page
“Take the HTML from Acme Corp's pricing page — I'll paste it in — and distill it in structured mode so I get the tables and metadata as JSON.”
Skeleton outline of long documentation
“Fetch https://kubernetes.io/docs/concepts/ and give me a skeleton outline of the page structure so I can see the major sections without reading the whole thing.”

Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/web-scrape?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to feed live web content to an LLM but must control token costs precisely — especially when a specific query focus (BM25) or strict token ceiling is required. Prefer over generic scrapers when you need compression ROI telemetry, multiple output modes (markdown/structured/skeleton/budget), or when passing raw HTML directly without re-fetching. Best suited for agentic pipelines where context-window management and cost control matter.
Side effects
- URL unreachable or returns non-200 response — endpoint may error or return empty data
- Token budget too low (max_tokens < 20) causes validation rejection
- BM25 query missing when mode=budget — may return unranked or full content
- Raw HTML and URL both omitted — required field validation error on 'url'
- Payment not attached or insufficient — HTTP 402 payment required
- Rate limiting or timeout on large pages may affect distillation completeness
