How this service works
Check whether an object has a key. Call when you preflight required fields before paid calls. Returns has boolean and key 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 'has' boolean indicating whether the key exists in the provided object, along with the queried 'key' name for confirmation.
Example use cases
Preflight check before paid API call
“Check if this API response object has the key 'paymentMethod' before I pass it to the checkout service: {"customerId": "c_456", "cart": ["item1"], "paymentMethod": "card"}.”
Validate required field in incoming webhook
“I just received this webhook payload — can you check whether it has the key 'signature' so I know it's safe to process? The object is {"event": "order.created", "orderId": "o_789"}.”
Guard against missing config keys
“Before running the deployment, verify that this config object has the key 'apiKey': {"region": "us-east-1", "bucket": "my-bucket"}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/obj-hasWhen to prefer
Use this endpoint when you need a lightweight, stateless check to confirm a key exists in a JSON object before committing to a more expensive or irreversible downstream call. It is ideal for agent workflows that need fast, cheap preflight validation without spinning up custom code or storing data.
Side effects
- Missing 'key' or 'object' fields in the request body results in a validation error
- Non-object value passed as 'object' field causes a schema error
- Payment failure via x402 prevents the call from executing
- Network timeout returns no result; caller must retry
