# AgentDiet Token Optimizer — URL/HTML Distiller with BM25 Budget Control

> AgentDiet Token Optimizer — URL/HTML Distiller with BM25 Budget Control is a paid API for AI agents from agentdiet.dev, paid per call via MPP, $0.001/call, status unknown.

Fetches and distills a webpage URL or raw HTML into compressed Markdown, structured JSON, skeleton outlines, or BM25-scored token-budget excerpts to reduce LLM context costs

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 agentdiet-dev-agentdiet-token-optimizer-url-html-distiller-with-bm25-e83a8b6a -d '<json body>'
```

Example prompt: Distill the content at https://stripe.com/docs/payments into clean markdown and keep it under 1500 tokens, focusing on payment integration steps using budget mode with a BM25 query of 'payment integration'.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content but must stay within a strict token budget or minimize LLM API costs. It is especially valuable for agentic pipelines that repeatedly fetch external URLs, for RAG systems needing clean Markdown, or when a specific topic focus (via BM25 query) should drive which portion of a page is retained. Prefer it over raw web scrapers when token efficiency and cost tracking (ROI proof) are required.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- Raw HTML is malformed or empty — distillation may produce minimal output
- Token budget (max_tokens) set too low for meaningful content extraction
- BM25 query provided without mode=budget — query may be ignored
- Rate limiting or payment failure via x402 — returns 402 with payment details
- Target URL blocks bots or requires authentication — fetch fails silently or partially

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt), an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd, plus optional cache hit/miss status and billing details.
