How this service works
Validate UUID string shape. Call when you check correlation IDs before storage keys. Returns valid boolean for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing a boolean field (e.g. 'valid') indicating whether the input string matches the UUID format. No external lookups are performed; the result is a purely local shape check.
Example use cases
Validate correlation ID before logging
“Before I insert this correlation ID 'f47ac10b-58cc-4372-a567-0e02b2c3d479' into the event log, can you confirm it's a valid UUID shape?”
Guard incoming webhook payload UUID
“I'm getting a webhook payload with an 'event_id' field set to '123e4567-e89b-12d3-a456-426614174000' — can you validate that it's a properly shaped UUID before I process it?”
Sanitize user-submitted identifier
“A user submitted 'not-a-real-uuid-at-all' as their session ID — can you check if that's actually a valid UUID so I know whether to reject it?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/is-uuid-shapeWhen to prefer
Choose this endpoint when you need a lightweight, stateless, no-network UUID format check — particularly useful in agent pipelines where you want to guard storage writes or API calls with a cheap ($0.001) local validation step before committing to more expensive operations. Prefer it over regex-in-code when you want a consistent, auditable external validation call that requires no API keys or auth setup.
Side effects

- Non-string input types may cause a validation error
- Payment not fulfilled via x402 protocol results in a 402 Payment Required response
- Malformed request body returns a 4xx error
