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.
Example use cases
Locate authentication logic in codebase
“Search the codebase for code related to user authentication and session management — I want to see the top matches so I can understand how login is implemented.”
Find database query patterns
“Can you search the indexed repo for any code that performs database queries or ORM operations and show me the top 5 results?”
Discover error handling conventions
“Search the repo for how errors and exceptions are handled — find the most relevant code snippets so I can follow the same patterns in my new feature.”
Technical details
Endpoint
GEThttps://x402-codesearch-poc.theliminalguy.workers.dev/search?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
