# Batch Random ID Generator (UUIDv4, UUIDv7, ULID, NanoID)

> Batch Random ID Generator (UUIDv4, UUIDv7, ULID, NanoID) is a paid API for AI agents from sigtap-outreach-api.sigtap.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-09-15).

Generates a batch of random unique identifiers in your choice of format: UUIDv4, UUIDv7, ULID, or nanoid

## 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 batch-random-id-generator-uuidv4-uuidv7-ulid-nanoid-de6ed2d5
```

Example prompt: Can you generate a batch of UUIDv7 IDs for me? I need about 10 of them for new database rows I'm inserting.

## When to prefer this

Use this endpoint when you need to generate multiple unique identifiers in bulk with a specific format (UUIDv4, UUIDv7, ULID, or nanoid) in a single API call. Prefer UUIDv7 or ULID when you need time-ordered sortable IDs for databases or event systems. Prefer nanoid for short URL-safe identifiers. This is especially useful for seeding databases, generating test data, or provisioning IDs for distributed systems before inserting records.

## Known failure modes

- Invalid or unsupported ID type requested — returns error
- Missing required parameters — returns 400-level error
- Network/worker timeout on the Cloudflare edge — returns 5xx

## How this service works

Paid micro-utilities for cold-email outreach agents: domain deliverability audits, cold-email grading, template generation, plus a tools toolbox (hashing, JWT decode, IDs, slugs, JSON, regex, crypto prices, domain age, weather). Paid via x402 (USDC on Base). One signature per call. No keys. FREE CHECK: GET /preview/<paid-path> (same URL with /preview/ prefix) returns a 200 demo sample - verify output shape before paying. PAID CALL: GET the url -> 402 challenge -> sign + retry with X-PAYMENT -> settled on-chain (USDC, Base). Ready-to-paste client: GET /llms.txt section "Pay in one call". Catalog+MCP twin: /llms.txt.

## Output

Returns a JSON object containing an array of generated unique IDs (field: 'ids'), the count of IDs generated, and the ID version/format used (e.g. 'v7', 'ulid', 'nanoid').
