How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing 'size' (an integer representing the number of top-level keys in the input object) and 'schema' (a string identifier 'delx/util-obj-size/v1' indicating the response format version).
Example use cases
Validating payload field count
“Before I send this JSON payload to my downstream service, can you check how many top-level keys it has? Here it is: {"id": "abc123", "status": "active", "amount": 500}”
Debugging unexpectedly large API response
“I got back this object from an API and I want to quickly know how many fields are in it — can you count the top-level keys for me? {"user": "...", "session": "...", "metadata": "...", "flags": "...", "prefs": "..."}”
Schema comparison during data migration
“I'm comparing two versions of a config object to see if they have the same number of fields. Can you tell me the size (number of top-level keys) of this one: {"host": "localhost", "port": 5432, "db": "mydb", "ssl": true}?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/obj-size?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC), pay-per-result computation of a JSON object's top-level key count without any signup or authentication overhead. It is well-suited for agents that need lightweight introspection of data payloads on-demand, especially in micropayment-enabled x402 workflows on Base or Solana.
Side effects
- Input is not a valid JSON object — may return an error or unexpected result
- Input is null or missing — likely returns a 400-style error
- Nested objects are not counted recursively, only top-level keys are measured
- Payment failure via x402 protocol prevents the call from completing
