Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-code-search-poc-85c3d8ba
```

Example prompt: Search the indexed repo for code that handles JWT token validation and return the top 5 most semantically relevant snippets.

## When to prefer this

Choose this endpoint when you need semantic (meaning-based) search over a pre-indexed code repository, especially when exact keyword matching would miss conceptually related code. Ideal for developer agents exploring an unfamiliar codebase, generating documentation, or finding implementation patterns.

## Known failure modes

- Query string missing or empty — returns error
- Repository index not available or not populated — returns no results
- Query too vague to produce meaningful matches — returns low-relevance results
- Payment not processed (x402 protocol failure) — request blocked
- Service downtime on Cloudflare Workers — 5xx error

## How this service works

Semantic code search over an indexed repo (top-5 matches)

## Output

Returns the top 5 semantically matched code snippets from the indexed repository, likely including file paths, relevant code excerpts, and similarity or relevance scores for each match.
