## 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 agentpay-web-search-7dfdc74d -d '<json body>'
```

Example prompt: Search the web for the best yield farming strategies on Base in 2026 and give me up to 8 results with their URLs and summaries.

## When to prefer this

Choose this endpoint when your agent needs live web search results without setting up API keys or recurring subscriptions — ideal for pay-as-you-go agent workflows that already operate on Base/USDC. Prefer it for crypto-native pipelines, autonomous agents with on-chain payment capability, or when you want minimal integration overhead for occasional web lookups.

## Known failure modes

- Query too short (under 2 characters) — validation error returned
- Query exceeds 400 character limit — truncation or rejection error
- max_results out of range (less than 1 or greater than 10) — validation error
- Payment fails or insufficient USDC balance — 402 Payment Required response with no results
- No results found for obscure or malformed query — empty results array returned
- Network or upstream search provider timeout — 5xx error response

## How this service works

Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.

## Output

A JSON object containing the original query, a count of results returned, and an array of result objects each with a URL, page title, and a short text snippet summarizing the page content. Typically returns 1–10 results depending on max_results requested.
