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 polymarket-odds-agentdiet-dev-web-content-distiller-with-bm25-budget-551b0dda -d '<json body>'
```

Example prompt: Distill the content at https://docs.stripe.com/api into clean markdown with a strict 2000-token budget, focusing on the query 'payment intents authentication' — I want to see the ROI and how many tokens you saved.

## When to prefer this

Choose this endpoint when you need to feed webpage content into an LLM but want to minimize token usage and cost — especially in agentic pipelines where context window space is precious. It is ideal when you have a specific query focus (use budget+BM25 mode) or need structured extraction from HTML without spinning up a full scraping pipeline. Prefer it over raw fetch+parse when you need built-in token budgeting, compression ROI metrics, and multiple distillation modes in a single call.

## Known failure modes

- URL unreachable or returns non-200 — fetch failure with error status
- HTML payload too large to process within time limits
- Invalid mode enum value — validation error
- max_tokens below minimum of 20 — schema validation error
- BM25 query provided without mode=budget — query may be ignored
- Rate limiting or payment failure via x402 micropayment protocol

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown, structured JSON, skeleton outline, or BM25-focused excerpt depending on mode), a 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD, plus optional cache hit/miss status and billing details.
