## 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 searchmux-consensus-search-675a1c30 -d '<json body>'
```

Example prompt: Search for 'quantum computing breakthroughs 2025' using consensus mode — I want results that multiple search engines agree on, so I know they're well-corroborated.

## When to prefer this

Choose this endpoint when you need higher-confidence search results validated across multiple search providers, rather than trusting a single index. It is especially useful for fact-checking, research tasks requiring corroboration, or any scenario where agreement between sources signals reliability. Prefer it over single-provider search when the cost of acting on a wrong result is high. It requires no account creation and uses x402 micropayments per call.

## Known failure modes

- One or more upstream providers (Exa, Tavily) unavailable — response may return degraded:true with partial results
- Payment not attached or insufficient — x402 payment required before results are returned
- Query string missing or malformed — likely returns 4xx error
- Both providers down simultaneously — no results returned
- Cache miss with slow upstream latency — response time increases significantly

## How this service works

Five accountless x402 tools for agent search, evidence, research deltas, and passive API discovery readiness.

## Output

A JSON object containing a ranked list of search results (URL, title, snippet, score), the providers queried (e.g. exa+tavily), an agreement object showing unique results count, sources queried, and corroborated results count, plus metadata including cache hit status, degraded flag, request ID, and generation timestamp.
