How this service works
Call when an agent needs whether a string is a valid uuid-nil. No network. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/id-uuid-nil first.
Output
Returns a boolean or validation result indicating whether the provided string matches the UUID nil format (all-zeros: 00000000-0000-0000-0000-000000000000), with no network calls required as the check is purely local string validation.
Example use cases
Detecting unset UUID fields
“I have a record with UUID field '00000000-0000-0000-0000-000000000000' — can you tell me if that's a nil UUID, meaning the field was never actually set?”
Validating UUID before database write
“Before I write this to the database, check if the UUID '00000000-0000-0000-0000-000000000001' is a nil UUID or a real one.”
Filtering nil UUIDs from a list
“I need to process this UUID from the API response: '00000000-0000-0000-0000-000000000000' — is it actually a nil UUID that I should skip?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/id-uuid-nil?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a UUID string is the nil/zero UUID (00000000-0000-0000-0000-000000000000) and do not want to implement the check yourself. Prefer the free sandbox endpoint (/v1/sandbox/id-uuid-nil) when available to avoid the $0.009 USDC cost. Choose this over general UUID validators when you specifically need nil UUID detection rather than version-specific UUID validation.
Side effects
- Empty or missing value field returns validation error
- String exceeding 20000 characters rejected
- Malformed request body returns error
- Payment of exact $0.009 USDC required or request is rejected
