# DOM Stripper – Web Distillation with BM25 Budget Control

> DOM Stripper – Web Distillation with BM25 Budget Control is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches a URL or accepts raw HTML and distills it into clean Markdown, structured JSON, skeleton outline, or a BM25-ranked token-budget excerpt

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 whale-momentum-agentdiet-dev-dom-stripper-web-distillation-with-bm25-e54f0729 -d '<json body>'
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into clean Markdown, keeping it under 2000 tokens and focusing on the BM25 query 'payment intents setup'?

## When to prefer this

Choose this endpoint when you need to reduce the token footprint of web content before passing it to an LLM, especially when working within strict context window budgets. It is ideal for agent pipelines that need to read documentation, news, or product pages without incurring high LLM token costs. Prefer the budget+BM25 mode when you have a specific question and want only the most relevant passage from a page. Use structured mode when the page contains tables or metadata you want as JSON. Prefer this over raw HTTP fetch + manual parsing when you want compression ROI metrics included automatically.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint returns an error status
- URL points to a non-HTML resource (PDF, binary) — distillation may fail or return empty data
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget used without providing a query — BM25 scoring has no focus signal
- Raw HTML provided is malformed or empty — distillation returns minimal or empty output
- Network timeout fetching the target URL — returns error status
- Payment not included or insufficient — HTTP 402 response blocking execution

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/dom-stripper)

## Output

Returns a 'data' object containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), along with an roi_proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes optional cache hit/miss status and billing details.
