How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a boolean field 'valid' indicating whether the submitted string conforms to the UUID format specification (e.g. {"valid": true} or {"valid": false}).
Example use cases
Validate user-submitted record ID
“A user just submitted '6ba7b810-9dad-11d1-80b4-00c04fd430c8' as their account ID — can you check if it's a valid UUID before I look it up in the database?”
Sanitize UUID from external API
“I got this ID back from an external service: 'not-a-real-uuid-abc123'. Can you validate whether it's a proper UUID so I know if I should trust it?”
Pre-flight check before database insert
“Before I insert this record, verify that 'xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx' is a correctly formatted UUID so I don't corrupt the primary key column.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/uuid/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost (~$0.0009 USDC) programmatic check on whether a string is a valid UUID — especially within agentic workflows on Base using x402 micropayments where spinning up a full validation library is impractical or where you need a pay-per-use utility without managing infrastructure.
Side effects
- Missing 'value' field in request body returns an error
- Empty string input may return valid: false
- Non-string types may cause schema validation failure
- Network or worker timeout returns no result
- Payment failure via x402 blocks the request before validation occurs
