# AgentTools UUID Generator & Validator

> AgentTools UUID Generator & Validator is a paid API for AI agents from agenttools-hub.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Generates cryptographically secure UUIDv4 (random) or UUIDv7 (time-sortable) identifiers, and validates any UUID's format, version, and variant bits.

## Facts

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 agenttools-uuid-generator-validator-db9e73b2
```

Example prompt: Can you generate a time-sortable UUIDv7 for me to use as a new database record ID?

## When to prefer this

Choose this endpoint when you need a cryptographically secure UUID from a real CSPRNG (not a pseudo-random fallback), need the time-sortable UUIDv7 format specifically for ordered distributed systems, or need strict validation of UUID format, version, and variant bits. Prefer this over language-level UUID libraries when operating in environments where library access is limited or auditability of the random source matters.

## Known failure modes

- Invalid 'op' parameter value returns an error
- Missing required 'value' parameter when op=validate
- Malformed UUID string during validation returns invalid status
- Invalid 'version' enum value (anything other than v4 or v7) returns an error
- Network timeout or service unavailability on Vercel hosting

## How this service works

Generate cryptographically random UUIDv4s or time-sortable UUIDv7s from a real CSPRNG, and validate any UUID's format, version and variant bits. Use this when an agent needs to random v4, sortable v7, plus strict validation.

## Output

For generate operations: a freshly minted UUID string (v4 random or v7 time-sortable) produced by a real CSPRNG. For validate operations: a structured result indicating whether the provided UUID string is valid, along with its detected version and variant bits.
