## 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 creator-desk-char-count-utility-a23a115f -d '<json body>'
```

Example prompt: How many characters are in the string 'Hello, World! This is my test sentence' — can you run it through the char-count utility and tell me the result?

## When to prefer this

Choose this endpoint when an autonomous agent or workflow needs a metered, pay-per-use character counting utility without spinning up its own text-processing logic. It is well-suited for pipelines that already use x402 micropayment infrastructure and need lightweight string measurement as a composable step — for example, validating content length before publishing, enforcing field limits, or logging text sizes at $0.01 USDC per call.

## Known failure modes

- Missing or null 'value' field returns an error or unexpected result
- Non-string value types may cause incorrect counts or errors
- Payment failure via x402 protocol blocks the request entirely
- Service unavailability on Render free-tier hosting causes timeouts or 503 errors
- Malformed options object may cause processing errors

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing the character count result (e.g. {"result": "93", "operation": "char_count"}), including the numeric count of characters in the input string and the operation identifier confirming which utility was invoked.
