# UUID v3 DNS Namespace Generator

> UUID v3 DNS Namespace Generator is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-02).

Generates a deterministic UUID version 3 using the DNS namespace from a given input text string

## Facts

- Endpoint: POST https://agentshelf.syntexa.ch/v1/uuid-name-v3-dns?utm_source=zero.xyz
- Price: $0.009/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/uuid-v3-dns-namespace-generator-3e091f26

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 uuid-v3-dns-namespace-generator-3e091f26 -d '<json body>'
```

Example prompt: Generate a deterministic UUID v3 in the DNS namespace for the text 'api.example.com' — I need the same UUID every time I pass that string.

## When to prefer this

Use this endpoint when you need a deterministic, reproducible UUID v3 in the DNS namespace and do not have a local UUID library available, or when operating in an environment where you want a paid, hosted, reliable computation. If a free sandbox version (POST /v1/sandbox/uuid-name-v3-dns) is available and acceptable, prefer that to avoid the $0.009 USDC charge. Choose this over UUID v4 endpoints when reproducibility from the same input is required.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Input text exceeding 100,000 characters is rejected
- Network or server errors return a 5xx response
- Payment failure or insufficient USDC balance results in a 402 error

## How this service works

Call when an agent needs a deterministic UUID v3 in the dns namespace. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/uuid-name-v3-dns first.

## Output

A deterministic UUID v3 string derived from the provided input text using the DNS namespace. The same input will always produce the same UUID output. The response includes the generated UUID identifier.
