# Web Distillation with BM25 Budget Control

> 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 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 token-intel-agentdiet-dev-web-distillation-with-bm25-budget-control-21f72f63 -d '<json body>'
```

Example prompt: Distill https://stripe.com/docs/payments into compressed 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 ingest web content into an LLM context while minimizing token usage and cost — especially when a strict token budget is required (mode=budget with BM25 ranking). Prefer it over raw web fetchers when you need compression metrics (roi_proof) to justify distillation ROI. Use the structured mode when you need tables and metadata extracted, or skeleton mode for quick outline navigation. It is particularly well-suited for agent pipelines that repeatedly read documentation or research pages and need predictable, budget-controlled outputs.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint may return an error status
- Invalid mode enum value — request rejected with validation error
- max_tokens set below minimum of 20 — rejected
- Both url and html omitted — url is required so request fails schema validation
- BM25 query provided without mode=budget — query may be silently ignored
- Payment failure via x402 — 402 response if payment is not completed
- Target page is JavaScript-heavy SPA — distillation quality may degrade

## 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/v1/distill)

## Output

Returns a JSON object containing: a 'data' field with the distilled content (Markdown string, structured JSON, skeleton, or BM25 excerpt depending on mode); an 'roi_proof' object with raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd; optional cache metadata (HIT/MISS, latency_ms); and billing details including fee_charged_usd.
