## How to call it through Zero

```sh
zero fetch --capability gocreative-hn-lookup-api-58fe979d
```

Example prompt: Can you look up Hacker News item 12345 and tell me its title, score, and who submitted it?

## When to prefer this

Choose this endpoint when you need quick, pay-per-call access to Hacker News item or user data without managing API keys or subscriptions. Ideal for AI agents that need occasional HN lookups billed in USDC micro-payments via x402 on Base, especially when no HN API key is available or desired.

## Known failure modes

- Invalid or non-existent HN item ID returns an error or empty result
- Missing required 'input' query parameter returns a 400-level error
- Payment failure (insufficient USDC balance) returns HTTP 402
- Rate limiting or service unavailability returns 5xx errors
- Querying a deleted or flagged HN item may return empty or partial data

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns structured Hacker News data for the given argument — likely including story or comment metadata such as title, URL, score, author, submission time, and child comment count, depending on the item type queried.
