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-web-content-distillation-with-bm25-budget-control-3da556fe -d '<json body>'
```

Example prompt: Fetch https://docs.stripe.com/payments/payment-intents and distill it into markdown using budget mode with the query 'payment confirmation webhooks', keeping it under 1500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web page content into an LLM context window and want to minimize token usage and cost — especially when you need BM25-ranked relevance filtering to a specific query (budget mode), or when you want structured JSON tables or skeleton outlines rather than raw HTML dumps. Prefer it over generic scrapers when token economy and compression ROI reporting matter.

## Known failure modes

- URL unreachable or returns non-200 status — fetch fails with error
- HTML too large or malformed — parsing may fail or produce degraded output
- max_tokens too low (below 20) — rejected by schema validation
- query missing when mode=budget — BM25 ranking cannot operate
- Payment not provided or invalid — HTTP 402 returned blocking execution
- Invalid mode enum value — request rejected
- Idempotency key collision on a different payload — may return cached mismatched result

## 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/pdf-extract)

## Output

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