How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object containing a 'ulids' array of one or more ULID strings. Each ULID is a 26-character, lexicographically sortable, URL-safe unique identifier encoding a timestamp and random component.
Example use cases
Bulk ID generation for database inserts
“I need to insert 20 new records into my database and want unique sortable IDs for each — can you generate 20 ULIDs for me right now?”
Single ULID for a new event record
“Generate a single ULID I can use as the ID for a new event I'm logging in my event-sourcing system.”
Distributed system ID assignment
“My microservice needs to assign unique, time-ordered IDs to 50 messages before publishing them to a queue — give me 50 ULIDs.”
Technical details
Endpoint
GEThttps://api.geekvault.dev/dev-tools/v1/ulid-generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ULIDs specifically (time-ordered, lexicographically sortable, Crockford Base32-encoded) rather than plain UUIDs. Ideal for distributed systems, event sourcing, or NoSQL databases where sort-by-creation-time matters. Prefer this over UUID generators when insertion order and sortability are requirements. The pay-per-call model (no API key or subscription) makes it convenient for sporadic or one-off generation tasks.
Side effects
- count parameter out of range (outside 1-100) — likely returns a validation error
- count provided as a non-integer string — may return a bad request error
- Payment failure via x402 — request rejected if USDC payment is not completed
- Service unavailability — 5xx error if the upstream generator is down
