Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 web-search-metasearch-api-965edd3a
```

Example prompt: Search across the web and Hacker News for 'open source LLM fine-tuning frameworks' and give me the top 5 results with titles, URLs, and snippets.

## When to prefer this

Prefer this endpoint when you need a quick, keyless, no-account web search that aggregates both general web results and Hacker News discussions in a single call with deduplication. Ideal for agents that need verifiable, signed results and want to avoid per-query API key management or upstream rate limits. Best for technical, startup, and news-adjacent queries where Hacker News coverage adds value.

## Known failure modes

- Missing or empty 'q' parameter returns a 400 bad request
- max_results outside 1-10 range may be clamped or rejected
- Upstream DuckDuckGo or Hacker News source unavailable may reduce result count
- Payment not processed results in 402 Payment Required
- Network timeout from the fly.dev host returns a 5xx error

## How this service works

Web search over x402 — metasearch across independent sources (DuckDuckGo + Hacker News) merged and deduped in ONE call: title + url + snippet per result. Served from our own box — no per-query upstream API cost, no rate-limit games, no API key, no account. GET ?q= [&max_results=1-10]. Free: GET /v1/web/search/preview. Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.

## Output

A JSON array of merged, deduplicated search results from DuckDuckGo and Hacker News, each entry containing a title, URL, and snippet. Results are cryptographically signed with Ed25519 and independently verifiable via the provider's public key endpoint.
