How this service works
Pay-per-call hashing and encoding for AI agents (USDC on Base)
Output
A JSON object containing an array of one or more UUID v4 strings (e.g. {"uuids": ["550e8400-e29b-41d4-a716-446655440000", ...]}), with the count matching the requested number.
Example use cases
Unique IDs for new database rows
“I'm inserting 10 new records into my database and need 10 fresh UUID v4s to use as primary keys — can you generate them for me?”
Idempotency keys for API calls
“I need 3 unique UUID v4 identifiers to use as idempotency keys before I fire off some payment requests.”
Test data generation for QA
“Generate 20 UUID v4s so I can populate my test fixtures with realistic-looking unique IDs.”
Technical details
Endpoint
POSThttps://x402-hash-api.vercel.app/api/v1/uuid?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to generate UUID v4 identifiers programmatically, especially in a pay-per-call agentic context using the x402 protocol with USDC on Base. Prefer it over local UUID libraries when the agent environment lacks a native UUID generation capability, or when auditability of paid API calls is important. Supports batch generation of up to 20 UUIDs per call.
Side effects
- Count out of range (must be 1–20): likely returns a 400 or validation error
- Unsupported UUID version (only v4 is supported): likely returns a 400 error
- Payment failure or insufficient USDC balance via x402: returns HTTP 402 Payment Required
- Service unavailable on Vercel infrastructure: returns 500 or timeout
