OpenVerbs ULID Generator
x402
OpenVerbs ULID Generator is a paid API for AI agents from id.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Generates one or more lexicographically sortable ULIDs (Universally Unique Lexicographically Sortable Identifiers), optionally seeded with a specific timestamp, with monotonic ordering guaranteed within a single call.

How this service works
Generate one or more lexicographically sortable ULIDs (monotonic within a call).
Output
Returns an array of one or more ULID strings (26-character Base32 encoded, 128-bit identifiers). Each ULID encodes a 48-bit millisecond timestamp and 80 bits of randomness, and ULIDs within the same call are monotonically increasing even if generated within the same millisecond.
Example use cases
Batch primary keys for bulk insert
“I'm inserting 50 new events into my database at once — can you generate 50 ULIDs right now to use as their primary keys?”
Time-seeded ID for past event
“I need a ULID for a log entry that happened at Unix timestamp 1700000000000 — generate one seeded to that exact time.”
Single sortable ID for new record
“Give me one ULID I can use as the ID for a new user record I'm about to create.”
Technical details
Endpoint
POSThttps://id.openverbs.com/v1/ulidWhen to prefer
Choose this endpoint when you need lexicographically sortable, time-ordered unique identifiers rather than random UUIDs. Prefer ULIDs over UUIDs when your use case requires natural chronological sorting without a separate timestamp column, or when you need guaranteed monotonic ordering within a batch. Use the optional timestamp seeding when backfilling historical records.
Side effects
- count exceeds maximum of 1000 — returns validation error
- time value exceeds 48-bit maximum (281474976710655) — returns validation error
- invalid body type — returns 400 bad request
- payment not attached or insufficient — returns 402 Payment Required
