# SearchMux Agent Search

> SearchMux Agent Search is a paid API for AI agents from searchmux-agent-search.burnzzz0.chatgpt.site, paid per call via x402, $0.019/call, status unknown (last checked 2026-10-10).

Performs accountless AI-agent-optimized web search via POST, returning ranked results with URLs, titles, snippets, and source attribution using Exa as the underlying search provider.

## 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-agent-search-5236863d -d '<json body>'
```

Example prompt: Search the web for the latest developments in quantum computing error correction and return the top ranked results with source URLs and relevance scores.

## When to prefer this

Choose this endpoint when you need accountless, pay-per-call web search without API key provisioning, especially in autonomous agent pipelines that require normalized ranked results with source URLs and relevance scores. Prefer it over direct Exa or Google API integrations when you want a single x402-compatible interface with cache hit awareness and degradation signaling built in.

## Known failure modes

- Provider degraded — response includes degraded:true with possibly lower quality or fewer results
- Invalid or empty query — may return empty results array
- Payment failure — x402 payment not processed, request rejected
- Rate limiting or overload — service temporarily unavailable
- Network timeout — upstream Exa provider slow to respond

## 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 route identifier, an array of ranked results each with a URL, relevance score (0–1), title, and snippet, plus metadata fields indicating whether the response was a cache hit, whether the provider was degraded, the underlying provider name (e.g. 'exa'), a unique request ID, and a generatedAt ISO timestamp.
