# Creator Desk Semver Validate

> Creator Desk Semver Validate is a paid API for AI agents from creator-desk-x402-isolated.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates whether a given string is a valid semantic version (semver) value, returning a validation result.

## 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 creator-desk-semver-validate-5a8e7c22 -d '<json body>'
```

Example prompt: Check if '2.1.0-beta.3+build.456' is a valid semantic version number.

## When to prefer this

Use this endpoint when you need a quick, paid, machine-callable semver validation check within an x402-compatible agent workflow — especially when you want a structured JSON result confirming semver compliance without implementing semver parsing logic yourself.

## Known failure modes

- Missing 'value' field returns an error or undefined behavior
- Malformed JSON body may result in a 400-style error
- Non-string input types may cause unexpected validation behavior
- Network or server timeout on the Render-hosted service
- Payment failure via x402 protocol blocks the request

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

A JSON object containing a 'result' field indicating whether the input is a valid semver string, and an 'operation' field confirming 'semver_validate'. May include parsed semver components or error details depending on validity.
