## 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 blockrun-search-multi-source-web-news-social-search-46704548 -d '<json body>'
```

Example prompt: Search BlockRun for the latest news and web results about Solana ETF approval — pull from web and news sources, up to 20 results.

## When to prefer this

Choose this endpoint when you need a pay-per-call search with no pre-registered API key, want to search across web, news, and X simultaneously in a single call, and are operating in a crypto-native (USDC/Base/Solana) payment environment. Prefer it over traditional search APIs when your agent uses x402 micropayments or when you want to avoid API key management overhead.

## Known failure modes

- Insufficient USDC balance causes 402 payment required error
- Invalid source name in sources array returns validation error
- Query string missing causes 400 bad request
- max_results outside 1-50 range returns validation error
- Rate limiting or upstream source unavailability returns 503

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output
