# RAG Diet – BM25 Budget-Controlled URL/HTML Distillation

> RAG Diet – BM25 Budget-Controlled URL/HTML Distillation is a paid API for AI agents from shopify-intel.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches and distills a URL or raw HTML payload into compact, agent-ready tokens using BM25 relevance scoring with a strict token budget ceiling.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability shopify-intel-agentdiet-dev-rag-diet-bm25-budget-controlled-url-html-0e3249b6 -d '<json body>'
```

Example prompt: Distill the page at https://shopify.dev/docs/api/admin-rest focusing on 'product variants' and keep it under 500 tokens using budget mode so I can fit it into my LLM context.

## When to prefer this

Choose this endpoint when you need to compress a specific webpage or raw HTML into a strict token budget before feeding it to an LLM, especially when BM25-relevance-ranked extraction matters (i.e. you have a focus query). Prefer it over a generic web scraper when token cost and ROI measurement are important, or when you need mode flexibility (Markdown, structured JSON, skeleton, or budget). It's ideal for RAG pipelines where context window space is limited and you need provable compression metrics.

## Known failure modes

- URL is unreachable or returns non-200 status — distillation fails with an error status
- max_tokens set too low (below 20) — rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored or trigger unexpected behavior
- Raw HTML payload is malformed or empty — distillation returns minimal or empty output
- Payment (x402 HTTP 402) fails or USDC balance is insufficient — request blocked before processing
- Rate limiting or server overload causing slow or failed fetch of target URL

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-intel.agentdiet.dev/v1/rag-diet)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton outline, or BM25 excerpt depending on mode), 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 optional cache hit/miss status and billing details.
