How this service works
Machine-callable x402-paid utilities for autonomous agents.
Output
A JSON object containing a 'result' field with the count of empty strings found in the input value, and an 'operation' field confirming 'empty_string_count'.
Example use cases
Audit form submission data quality
“I have this object from a user form submission — can you count how many of the fields came back as empty strings so I know how incomplete it is? Here's the data: {"name": "Alice", "email": "", "phone": "", "address": "123 Main St"}”
Validate CSV row before processing
“Before I process this row from my CSV, count how many values are empty strings: ['2024-01-15', '', 'USD', '', '500', '']”
Check API response completeness
“I got back this array of strings from an API response — how many of them are empty strings? ['foo', '', 'bar', '', 'baz', '', '']”

Endpoint
POSThttps://creator-desk-x402-isolated.onrender.com/v1/utility/empty-string-count?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.01 USDC) machine-callable computation to count empty strings in a value — especially useful in automated data quality pipelines or agent workflows where you need a deterministic count without writing custom code.
Side effects
- Missing or malformed 'value' input may return an error or unexpected result
- Payment failure via x402 protocol will block the call
- Deeply nested structures may not be traversed if options are not configured correctly
- Non-JSON-serializable input may cause a parse error
