## 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 rag-gedx402-com-ai-search-query-7718aabb
```

Example prompt: Search the index 'kb-001' for the top 5 most relevant chunks about 'quarterly revenue forecasting best practices' using hybrid retrieval, with reranking enabled.

## When to prefer this

Choose this endpoint when you need pay-per-use RAG search without managing API keys or infrastructure — ideal for agents that need to query a specific pre-indexed knowledge base (identified by :id) using natural language, with optional hybrid/vector/keyword retrieval modes and reranking, paying micro-amounts in USDC on supported chains.

## Known failure modes

- Invalid or non-existent index ID returns 404 or empty results
- Insufficient USDC payment results in 402 Payment Required response
- top_k value outside 1–50 range may return validation error
- Unsupported retrieval_type enum value causes request rejection
- Empty query string with no messages array may return error or zero results
- Network timeout on slow queries with large top_k or reranking enabled

## How this service works

Run Cloudflare AI Search inference on Cloudflare Workers AI (cloudflare-ai-search) via POST JSON. Pay per request with USDC on Base, Polygon, Arbitrum, World, or Solana (x402 v2); see x-payment-info for price bounds and accepted networks.

## Output

A JSON object containing a count of returned chunks and an array of chunk objects, each with an ID, the text content, and a relevance score (0–1). Example: {count: 1, chunks: [{id: 'chunk-1', text: '...', score: 0.9}]}.
