## 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-repeat-string-cd236b78 -d '<json body>'
```

Example prompt: Repeat the string '---' 40 times so I can use it as a section separator in my report.

## When to prefer this

Choose this endpoint when an AI agent needs to repeat a string a fixed number of times server-side without running a local loop — particularly useful in serverless, sandboxed, or agent environments where local iteration is unavailable or undesirable. Ideal for generating fixture data, separators, or repeated test payloads deterministically with no API key or subscription required.

## Known failure modes

- Input text exceeds 100,000 character limit — returns a structured validation error (not billed)
- Missing or invalid N parameter — returns validation error
- N is zero or negative — may return empty string or validation error
- Network or payment authorization failure — call not completed

## How this service works

Repeat a string N times. Handy for fixtures, separators, or test payloads without local loops. Returns the repeated string and N used. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

## Output

Returns a JSON object containing the fully repeated string (the input text concatenated N times) and the value of N that was used, billed at $0.001 USDC per successful call via x402 on Base; validation errors are not billed.
