## 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-repeat-string-utility-4fa56a02 -d '<json body>'
```

Example prompt: Repeat the text 'hello' exactly 5 times for me.

## When to prefer this

Choose this endpoint when you need a simple, pay-per-use string repetition utility with no signup or API key required, billed via USDC micropayment on Base or Solana. Useful in agent pipelines where lightweight text manipulation is needed on demand without provisioning a full string-processing library.

## Known failure modes

- Missing required 'text' field returns an error
- Missing or non-integer 'count' field returns a validation error
- Payment not received (402) blocks execution
- Very large count values may be rejected or truncated
- Network timeout if the service is temporarily unavailable

## How this service works
