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').
Example use cases
Seed database with unique primary keys
“I need to pre-generate 20 ULIDs to use as primary keys before I insert a batch of records into my database — can you get those for me?”
Generate time-sortable IDs for event logs
“Give me a bunch of UUIDv7 IDs — I need about 15 — for tagging a set of events in my logging system so they're naturally sortable by creation time.”
Create short random IDs for URL shortener
“I need a batch of nanoid strings to use as short unique codes in my URL shortener — can you generate 10 of them?”
Technical details
Endpoint
GEThttps://sigtap-outreach-api.sigtap.workers.dev/tools/uuidWhen to prefer
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.
Side effects
- Invalid or unsupported ID type requested — returns error
- Missing required parameters — returns 400-level error
- Network/worker timeout on the Cloudflare edge — returns 5xx
