## 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-ae69f6e1 -d '<json body>'
```

Example prompt: Can you distill https://stripe.com/docs/api into clean markdown and keep it under 2000 tokens, focusing on the 'authentication' topic using budget mode so I don't blow up my context window?

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost — especially when you have a specific focus query (BM25 budget mode) or need structured extraction from HTML. Prefer over raw web scraping when token efficiency and compression metrics matter, or when you need multiple distillation modes (markdown, skeleton, structured) in a single API with built-in cost-savings proof.

## Known failure modes

- URL unreachable or returns non-200 — fetch fails with error status
- HTML too large or malformed — distillation may truncate or fail
- max_tokens below minimum of 20 — validation error
- mode=budget used without providing a query — may return unfiltered or error
- Payment not completed via x402 — 402 response blocking execution
- Idempotency key reuse with different parameters — 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://polymarket-odds.agentdiet.dev/v1/context-trimmer)

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown, structured JSON, skeleton outline, or BM25-focused 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.
