## 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-hn-pulse-hacker-news-intelligence-distiller-70648568
```

Example prompt: Fetch the current Hacker News pulse using AgentDiet and give me a compressed digest of what's trending — I want the distilled summary with the compression ratio so I can see how many tokens were saved.

## When to prefer this

Choose this endpoint when you need a token-efficient, compressed digest of Hacker News trends for use inside an AI agent context window. Ideal when token cost is a concern and you want provable compression ratios rather than raw full-text HN content. Best for agents operating on tight context budgets that still need real-time tech community intelligence.

## Known failure modes

- Payment failure via x402 if USDC balance on Base is insufficient
- Empty or malformed query param returns degraded or empty data field
- HN source unavailable results in error or empty data response
- Rate limiting or node unavailability returns non-200 status

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing distilled Hacker News content, a 'status' field ('ok'), and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), which quantifies token savings achieved by the distillation.
