JSON UUID Fields Check
x402
JSON UUID Fields Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).
Validates selected fields of a JSON object for canonical UUID format, returning counts, normalized values, and a versioned deterministic result.

How this service works
JSON UUID Fields Check: checks selected fields for canonical UUID text shape using only bounded caller-supplied values. Call when you need a bounded json uuid fields check result before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON UUID Fields Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base or…
Output
A versioned deterministic JSON result containing: which specified fields pass or fail UUID format validation, counts of valid/invalid fields, normalized UUID values for passing fields, and a versioned result contract envelope — all computed in-memory without data retention.
Example use cases
Pre-flight check before strict API call
“I'm about to send this order payload to our fulfillment service which requires all ID fields to be valid UUIDs — can you validate that 'orderId', 'customerId', and 'warehouseId' all look like proper UUIDs before I submit?”
Catching malformed UUIDs in user input
“A user just submitted a form and I need to verify that the 'profileId' and 'tenantId' fields they provided are correctly formatted UUIDs — can you check the object I have and tell me which ones pass or fail?”
Normalizing UUID casing in a batch plan
“I have a JSON object with fields 'transactionId' and 'accountRef' that might have mixed-case or improperly formatted UUIDs — can you validate them and give me back normalized canonical versions along with how many passed?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-uuid-fields-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, in-memory check that specific JSON fields contain canonical UUID strings before passing structured data to a downstream system with a strict contract. Prefer it over general-purpose schema validators when UUID field compliance is the specific concern, and over writing custom validation logic when a pay-per-call microservice is more convenient. Ideal for agent pipelines that need a versioned, reproducible validation result with counts and normalized output.
Side effects
- Fields array exceeds 256 items — request rejected
- Object exceeds 128 properties — request rejected
- Individual field string exceeds 8192 characters — rejected
- Malformed JSON input — parse error returned
- Payment not included or insufficient — 402 response
- Fields list references keys not present in the object — may return not-found or null results for those fields
