## 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 codepulse-api-web-search-98b94311 -d '<json body>'
```

Example prompt: Search the web for 'best open-source LLM frameworks 2026' and give me the top results with their titles and URLs.

## When to prefer this

Use this endpoint when an AI agent needs real-time web search results without managing API keys, and is willing to pay $0.03 USDC per call via x402 on Base. Ideal for agents that need fresh web data on demand in a pay-per-use model without subscription overhead.

## Known failure modes

- Query not supported — 'supported' field returns false with lower confidence
- Empty results list if no relevant pages are found
- Ambiguous or very short queries may return low-confidence results
- Payment failure if USDC balance is insufficient on Base
- Rate or timeout errors from the underlying search provider

## How this service works

Performs web searches using a free DuckDuckGo HTML parser. Returns organic search results.

## Output

Returns a JSON object containing a list of search results, each with a URL, title, and snippet; plus a confidence rating (e.g. 'high'), a data_as_of date, any warnings, and a disclaimer. The supported field confirms the query type is handled.
