## 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-for-agents-b91bbf61 -d '<json body>'
```

Example prompt: Search the web for 'best open-source LLM frameworks in 2025' and give me the top 7 results with their titles, URLs, and a short description of each.

## When to prefer this

Choose this endpoint when an AI agent needs fresh, citable web results without setting up an API key or account — ideal for pay-per-call agentic pipelines using x402/USDC on Base. Prefer it over cached or subscription-based search APIs when freshness and per-call economics matter, or when the agent must avoid storing credentials. Not suited for image search, deep domain-specific databases, or structured data lookups.

## Known failure modes

- Query too short (under 3 characters) — validation error returned
- Query exceeds 300 characters — request rejected
- max_results outside 1–10 range — validation error
- Payment failure or insufficient USDC balance — x402 payment error, no results returned
- Search provider upstream timeout or outage — 5xx error with no results
- No relevant results found for highly specific or obscure queries — empty results list

## How this service works

Use when an agent needs fresh web results for a question. Send a plain query and get up to 10 ranked results with title, URL, publish date and a short excerpt, ready to cite. Fast, no account and no API key on your side; pay per call with x402. Results come from a licensed search provider and are not cached across customers.

## Output
