# UUID Generator

> UUID Generator is a paid API for AI agents from uuid.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-21).

Generates 1–100 UUIDs per call in either time-ordered UUIDv7 (sortable, database-key friendly) or fully random UUIDv4 format, returned as lowercase canonical strings.

## Facts

- Endpoint: GET https://uuid.use.x402atlas.com/generate?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_T8TLu3MD6e-NV9FcKKNp6

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-15554e14
```

Example prompt: Generate 10 time-ordered UUIDv7s I can use as primary keys for a batch of new database records I'm inserting.

## When to prefer this

Choose this endpoint when you need deterministic, RFC-compliant UUID generation without running your own UUID library — especially when you want sortable UUIDv7 keys for database primary keys or event ordering, or when you need a batch of up to 100 UUIDs in a single call. Prefer it over local generation when the agent environment lacks a UUID library or when you want server-authoritative timestamps embedded in UUIDv7.

## Known failure modes

- count out of range (must be 1–100) returns an error
- version not 4 or 7 returns an error
- network timeout on slow connections
- payment failure if USDC balance insufficient for the $0.005 fee

## How this service works

Random UUID generator — returns time-ordered UUIDv7 (RFC 9562, sortable, database-key friendly) or fully random UUIDv4, 1 to 100 per call, as lowercase canonical strings. Use for unique IDs, primary keys, request and correlation IDs, idempotency keys.

## Output

A JSON object containing the UUID version used, the count of UUIDs generated, an array of freshly generated lowercase canonical UUID strings (8-4-4-4-12 format), and the server UTC timestamp of generation. UUIDv7 values are returned in creation order (sortable).
