How this service works
Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/rag-token-diet)
Output
Returns a distilled payload with a 'data' object containing the compressed content (markdown, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and ROI multiplier. Also includes cache status and billing details.
Example use cases
RAG pipeline documentation ingestion
“Fetch and compress the Stripe docs page at builtin://stripe-docs into structured markdown under 800 tokens so I can include it in my agent's context without hitting token limits.”
Relevance-focused budget extraction
“Grab the page at https://openai.com/research/gpt-4 and pull out only the content relevant to 'safety benchmarks' — keep it under 300 tokens using budget mode.”
Skeleton outline for long article
“Give me a skeleton outline of https://en.wikipedia.org/wiki/Transformer_(machine_learning_model) so I can see the document structure without reading the whole thing.”

Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/rag-token-diet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to read a live webpage but must stay within a token budget — especially for RAG pipelines, documentation grounding, or any workflow where raw HTML would consume too many context tokens. The BM25 budget mode makes it uniquely suited for query-focused extraction where only topically relevant sections matter. Prefer this over generic scrapers when you need both compression metrics (ROI proof) and multiple output formats (markdown, structured, skeleton).
Side effects
- Invalid or unreachable URL returns an error status
- mode=budget without a query or max_tokens may return unfiltered content
- HTML too large may exceed processing limits
- Paywalled or bot-blocked URLs may return incomplete content
- max_tokens below 20 is rejected by schema validation
- Payment required (HTTP 402) if no valid x402 payment method is provided
