## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-line-count-api-0aed3601 -d '<json body>'
```

Example prompt: Count the lines and characters in this text, and tell me how many are non-empty — include empty lines in the count: 'Hello world\n\nThis is a test\nDone'

## When to prefer this

Choose this endpoint when you need a cheap, verifiable, pay-per-call utility to count lines and characters in text without any setup or subscription. Ideal for AI agents that need to audit text structure, validate file formatting conventions (e.g., trailing newlines), or preprocess content before downstream operations. At $0.001 USDC per call with no signup required, it suits high-frequency agent workflows that need deterministic text metrics.

## Known failure modes

- Missing or empty text field returns error
- Non-string text input may cause validation failure
- Extremely large text strings may time out or be rejected
- Malformed JSON request body returns 400-level error
