Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh

```

## When to prefer this

Choose PHION Search when you need web search results that include explicit source attribution and signed/verified delivery — ideal for agentic workflows where result provenance and authenticity must be auditable. Prefer this over generic search APIs when you need normalized output format and cryptographic assurance of result integrity.

## Known failure modes

- Query too vague or empty — returns no results or error
- Payment not included or invalid — returns 402 Payment Required
- Malformed request body — returns validation error
- Search provider timeout — returns upstream error
- Rate limiting on high-frequency queries — returns 429 Too Many Requests
