## 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-regex-escape-utility-54c9cd40 -d '<json body>'
```

Example prompt: Escape this string so I can safely use it as a literal pattern inside a regex: 'user.name+tag@example.com'

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically escape strings for regex use at $0.01 USDC per call via the x402 micropayment protocol, particularly in autonomous pipelines where importing a local regex-escape library is not feasible or the agent environment is sandboxed. Prefer a local library solution for high-volume or latency-sensitive workloads.

## Known failure modes

- Missing or null 'value' field may return a validation error or empty result
- Unsupported option keys in the 'options' object may be silently ignored or cause a 400 error
- Network timeout if the Render.com instance is cold-starting
- Payment failure via x402 protocol results in 402 status and no result returned

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing the escaped string in the 'result' field and the operation name 'regex_escape' in the 'operation' field, confirming the transformation that was applied.
