# SignalDesk AI Go Module Version Lookup

> SignalDesk AI Go Module Version Lookup is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Fetches the latest published version and metadata for a Go module from the public Go module proxy

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 signaldesk-ai-go-module-version-lookup-2f555dcf
```

Example prompt: What is the latest published version of the github.com/google/uuid Go module?

## When to prefer this

Use this endpoint when you need fast, paid-metered access to the latest Go module version metadata via proxy.golang.org without setting up your own proxy queries. Ideal for AI agents that need to resolve Go dependency versions programmatically, audit go.mod files, or check for updates in automated pipelines. Prefer over raw proxy.golang.org calls when you need a structured JSON response with expiry and fetch timestamps included.

## Known failure modes

- Module path not found on proxy.golang.org returns an error response
- Invalid or malformed module path (not matching pattern ^[A-Za-z0-9._~/-]+$) returns a validation error
- Private or internal modules not listed on the public proxy will not resolve
- Rate limiting or quota exhaustion from free execution bounds may return a 429 or error
- Network timeout when upstream proxy is slow

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the module path, latest version string (e.g. v1.6.0), publication timestamp, the source URL used to fetch the data from proxy.golang.org, fetch and expiry timestamps, and a flag indicating the data was transformed.
