# APISphere UUID Generator

> APISphere UUID Generator is a paid API for AI agents from apisphere.us.ci, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-11).

Generates one or more UUIDs (v4 random or v7 time-ordered) in standard, compact, or uppercase format, paid per-call in USDC via x402.

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 apisphere-uuid-generator-e709fc86 -d '<json body>'
```

Example prompt: Generate 5 time-ordered UUIDs (version 7) in compact format with no dashes — I need them for a batch of new database rows.

## When to prefer this

Choose this endpoint when your agent needs UUIDs on demand without pre-registration or API keys, particularly in automated workflows where payment is handled programmatically via x402/USDC. Prefer v7 when time-ordering of identifiers matters (e.g., event logs, append-only tables); prefer v4 for purely random, opaque IDs. Use the compact format when your target system cannot store dashes.

## Known failure modes

- count out of range (must be 1–100) returns a validation error
- invalid version (not 4 or 7) returns a bad request error
- invalid format enum value returns a validation error
- payment failure or insufficient USDC balance prevents call from completing
- network timeout or service unavailability returns a 5xx error

## How this service works

Pay-per-call APIs for AI agents. No signup, no API keys — agents pay in USDC on Base via x402. Live endpoints for crypto prices and geocoding.

## Output

Returns a JSON object containing the list of generated UUIDs, the count, the UUID version used, and metadata including request ID and latency in milliseconds.
