## 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 whatchuneed-llm-search-70bbc01e -d '<json body>'
```

Example prompt: Search for 'best open-source LLMs in 2025' and give me a synthesized summary of what you find, along with the top result URLs.

## When to prefer this

Choose this endpoint when you need both raw search result links (URL, title, snippet) AND an LLM-synthesized summary in a single call, paid per-use via crypto microtransaction. Ideal for agents that need grounded, cited answers without maintaining a search API subscription.

## Known failure modes

- Empty or vague query may return poor results or empty results array
- Payment failure via x402 protocol results in 402 response and no data
- Synthesis field may be empty if no relevant results are found
- Rate limiting or service downtime on the vercel.app backend
- Query too long or malformed JSON may result in 400 bad request

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a JSON object containing a 'results' array (each item has url, title, and snippet fields) and a 'synthesis' string — an LLM-generated summary that distills the top results into a coherent answer.
