```

Example prompt: Count how many empty strings are in this array for me: ['hello', '', 'world', '', '', 'test']

## When to prefer this

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.

## Known failure modes

- 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

## How this service works
