# AgentDiet Web Distillation API (BM25 Budget Mode)

> AgentDiet Web Distillation API (BM25 Budget Mode) is a paid API for AI agents from llms-generator.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches and distills a URL or raw HTML into compact, agent-ready tokens using multiple extraction modes including BM25-ranked budget excerpts with strict token ceilings

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 llms-generator-agentdiet-dev-agentdiet-web-distillation-api-bm25-1a8465f8
```

Example prompt: Distill the content at https://stripe.com/docs/payments into compact markdown using budget mode, focus the BM25 query on 'payment intents' and cap the output at 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM and must stay within a token budget — especially when BM25-ranked relevance filtering is needed to extract only query-relevant passages. Ideal for agentic pipelines that repeatedly fetch documentation, news, or research pages and need to minimize LLM inference costs via compression. Prefer over generic scrapers when token-efficiency ROI reporting and multiple distillation modes (markdown, structured, skeleton, budget) are needed in one call.

## Known failure modes

- URL is unreachable or returns non-200 — fetch fails and status reflects error
- HTML payload is malformed or empty — distillation returns empty or low-quality output
- max_tokens set too low (below 20) — request rejected with validation error
- mode=budget without a query parameter — BM25 ranking cannot be applied, may return generic excerpt
- Payment not provided or insufficient — HTTP 402 returned blocking the request
- URL is a dynamic JavaScript-heavy SPA — raw HTML fetch may miss rendered content

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), plus an 'roi_proof' object showing raw vs distilled token counts, compression ratio, tokens saved, ROI multiplier, and estimated LLM cost saved. Also includes cache status and billing details.
