# AgentDiet Web Distillation with BM25 Budget Control

> AgentDiet Web Distillation with BM25 Budget Control is a paid API for AI agents from token-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 into compressed Markdown, structured data, skeleton outline, or a BM25-ranked token-budget excerpt, returning ROI metrics on tokens saved.

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 token-intel-agentdiet-dev-agentdiet-web-distillation-with-bm25-budget-cdbb507c -d '<json body>'
```

Example prompt: Distill the page at https://stripe.com/docs/payments/accept-a-payment into markdown, keeping it under 800 tokens and focusing on the BM25 query 'accept card payment integration'.

## 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 you have a strict context window budget or want to focus only on query-relevant passages via BM25 ranking. It is distinctly valuable over generic scrapers because it returns ROI metrics (tokens saved, cost saved) and supports four distillation modes including token-budget-controlled BM25 excerpting — ideal for autonomous agent pipelines that need to self-regulate context usage and LLM costs.

## Known failure modes

- URL unreachable or returns non-200 — fetch error returned
- HTML payload missing when url not provided and html field empty — validation error
- max_tokens below minimum of 20 — schema validation rejection
- BM25 query empty in budget mode — may return unfiltered or error
- Idempotency key reuse with different parameters — may return cached prior result
- Payment not fulfilled (x402) — 402 Payment Required 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://token-intel.agentdiet.dev/api/diet)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown string, structured JSON tables, skeleton outline, or BM25-ranked excerpt depending on mode), plus 'roi_proof' showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd, along with cache hit/miss status and billing details.
