## 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 saylor-innovations-runtime-versions-api-a09ff1ed
```

Example prompt: What are the latest stable and LTS versions of Node.js, Python, and PostgreSQL right now, including which release cycles are still supported?

## When to prefer this

Choose this endpoint when you need authoritative, up-to-date stable and LTS version data for a broad set of popular runtimes and databases in a single call. It is especially useful for dependency auditing, DevOps tooling, onboarding documentation, or any workflow that needs to compare current installed versions against official latest releases without scraping individual project release pages.

## Known failure modes

- Invalid runtime name in 'names' query param returns empty or error response
- Stale data if upstream version sources haven't been refreshed recently
- Network timeout if upstream data aggregation is slow
- Unrecognized runtime identifiers silently omitted from results

## How this service works

Latest runtime versions - current stable and LTS release of Node.js, Python, Go, Java, Ruby, PHP, .NET, Rust and databases with supported cycles

## Output

A JSON object containing an array of runtime entries, each with the product name, latest stable version, latest LTS version, latest LTS and stable cycle identifiers, EOL date, list of supported cycles, and latest release date. Also includes a count of returned items, the data source reference, and a UTC timestamp of when the data was last checked.
