How this service works
Check whether an object is empty. Call when you gate agent workflows on empty JSON bodies. Returns empty flag and size 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 an empty boolean flag indicating whether the object has zero keys, along with the size (number of top-level keys) of the object.
Example use cases
Guard agent workflow on empty payload
“Before we process this API response, check if the returned object is empty — if it is, I want to skip the next step entirely.”
Validate incoming webhook body
“I just received a webhook and the body is supposed to have data in it — can you tell me if this object is empty or if it actually contains fields?”
Pre-flight check before data enrichment
“Check if this JSON object has any keys in it before we try to enrich it — I don't want to waste a call if it's completely empty.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/obj-emptyWhen to prefer
Choose this endpoint when you need a lightweight, local, no-network check to gate agent workflows on whether a JSON object body is empty. It is ideal for pre-flight guards before expensive downstream API calls, and useful when you want a deterministic empty+size signal without writing inline logic.
Side effects
- Non-object input (e.g. array or primitive) may return an error or unexpected result
- Malformed JSON body causes a 400-level error
- Missing 'object' field in request body returns an error
- Network timeout or service unavailability returns 5xx
