How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with a status field and an array of one or more UUID v4 strings (e.g. '550e8400-e29b-41d4-a716-446655440000'). The number of UUIDs matches the requested count (default 1, max 100).
Example use cases
Seed database with unique keys
“I need to seed my database with 20 unique UUID v4 values — can you generate them all at once?”
Session token generation for new users
“Generate a single UUID v4 I can use as a session token for a new user signing up.”
Batch ID creation for an import job
“I'm running an import job and need 100 unique UUIDs generated right now to assign to each incoming record.”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/uuid/generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or automated pipeline needs to generate one or many UUID v4 values on demand without depending on a local library — especially in environments where calling an external micro-service is simpler than running code. The x402 micropayment model ($0.001 USDC) makes it practical for machine-to-machine workflows where billing per call is acceptable. Prefer it for batch UUID needs (up to 100 at once) in serverless or constrained runtimes.
Side effects
- count out of range (must be 1–100) returns a validation error
- missing required body fields returns a 400-level error
- payment not provided or insufficient triggers an x402 payment-required response
- malformed JSON body results in a parse error
- server unavailability on Railway returns a 502/503
