## 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 cve-intel-agentdiet-dev-web-url-context-distiller-bm25-budget-control-c30e046e
```

Example prompt: Fetch https://stripe.com/docs/api and distill it into compact markdown within a 500-token budget, focusing on the query 'authentication headers'.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content but must stay within a token budget or reduce LLM costs. Especially useful when a documentation page, article, or HTML blob is too verbose to pass directly into a prompt. The BM25 budget mode is ideal when only query-relevant passages are needed from a large page. Prefer over general-purpose scrapers when you specifically need token-optimized, agent-ready output with compression metrics.

## Known failure modes

- Invalid or unreachable URL returns an error status
- mode=budget without a query or max_tokens may produce unconstrained output
- Very large pages may hit internal processing limits
- HTML payloads with heavy JavaScript rendering may not distill fully
- max_tokens below 20 is rejected by schema validation
- Payment failure via x402 blocks execution

## How this service works

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

## Output

Returns a distilled representation of the fetched webpage or HTML — either clean Markdown, structured JSON tables/metadata, a skeleton outline, or a BM25-focused budget excerpt — along with ROI proof metrics including raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved. Also includes cache hit/miss status and billing details.
