## 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-hackernews-trends-e96cb69b
```

Example prompt: What are the trending topics on HackerNews right now? Pull the distilled summary so it fits within my context window.

## When to prefer this

Choose this endpoint when you need HackerNews trending data in a token-efficient, compressed format specifically designed for AI agent context windows. It is ideal when you want to minimize token usage while still getting actionable trend signals, and when you are operating in a B2A/A2A workflow that supports x402 micropayment settlement on Base. Prefer this over scraping HackerNews directly when context window size is a constraint.

## Known failure modes

- Payment not settled in USDC on Base — returns 402 Payment Required
- HackerNews upstream unavailable — may return empty data or error status
- Malformed query parameters — request rejected with validation error
- Rate limiting or node unavailability — service temporarily unreachable

## How this service works

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

## Output
