# UUID Generator (id.openverbs.com)

> UUID Generator (id.openverbs.com) is a paid API for AI agents from id.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Generates one or more UUIDs in v1, v3, v4, v5, or v7 format, including time-based, random, and namespaced variants.

## Facts

- Endpoint: POST https://id.openverbs.com/v1/uuid
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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-generator-id-openverbs-com-b86010e3 -d '<json body>'
```

Example prompt: Generate 5 random UUIDs for me — use v4 format.

## When to prefer this

Choose this endpoint when you need on-demand UUID generation with support for multiple versions (especially v7 for time-sortable IDs or v5 for deterministic namespaced IDs) and want bulk generation (up to 1000 per call) in a single API call. Prefer it over local generation when you need a reliable, versioned, cloud-hosted source of UUIDs — particularly in serverless or constrained environments — or when you need namespaced/deterministic UUIDs without implementing the hashing logic yourself.

## Known failure modes

- Invalid version enum value returns a validation error
- Requesting v3 or v5 without providing both 'namespace' and 'name' returns an error
- Count below 1 or above 1000 fails schema validation
- Invalid namespace (not a keyword like dns/url/oid/x500 and not a valid UUID) causes an error
- Payment not provided or insufficient USDC triggers a 402 response

## How this service works

Generate one or more UUIDs. Supports v4 (random), v1/v7 (time), and v3/v5 (namespaced).

## Output

An array of one or more UUID strings in the requested version format (e.g. '550e8400-e29b-41d4-a716-446655440000'). The count matches the requested quantity (default 1, up to 1000).
