## 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 riley-craig-x402-agent-store-web-search-5fe64526
```

Example prompt: Search for 'vector database' across Hacker News, GitHub, Stack Overflow, and Wikipedia and give me the top 8 results from each source.

## When to prefer this

Choose this endpoint when an AI agent needs fast, multi-source developer-focused search results (Hacker News, GitHub, Stack Overflow, Wikipedia) without any API key signup, and is able to pay per-call in USDC via x402 on Base. Prefer over traditional search APIs when operating in a permissionless, agent-native payment context or when developer/technical content is the primary target.

## Known failure modes

- Missing required 'q' query parameter returns a 400 error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Invalid 'sources' value (not in allowed enum) may return empty or error
- limit value outside 1-10 range may be clamped or rejected
- Upstream source (e.g. GitHub, HN) temporarily unavailable reduces result count

## How this service works

One call, many sources: search Hacker News, GitHub, Stack Overflow, and Wikipedia by keyword and get back a unified, ranked result set — titles, URLs, scores/stars, and snippets — across all of them at once. The general research/search read agents make to ground answers, find code, surface discussion, and gather context. No API keys, no per-source accounts, free upstreams. Pass `sources` to narrow (hackernews,github,stackoverflow,wikipedia).

## Output

A JSON object containing the original query string, a total count of results, a list of sources searched, and an array of result objects each with a URL, title, snippet, source label, and numeric relevance score.
