## 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-user-agent-trim-utility-684d88c2 -d '<json body>'
```

Example prompt: Can you trim and clean this user-agent string for me: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)   AppleWebKit/537.36  '? I need a normalized version without extra whitespace or junk.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use microservice to trim and normalize user-agent strings as part of an automated agent pipeline, especially when you want to avoid spinning up your own string-processing infrastructure. It is best suited for low-volume, on-demand cleaning of individual user-agent values where the $0.01 USDC per-call cost is acceptable.

## Known failure modes

- Missing or null 'value' field may return an error or empty result
- Malformed options object may cause a 400 bad request
- Payment failure or insufficient USDC balance blocks the call with a 402 response
- Service downtime on Render free tier may cause intermittent 503 errors
- Extremely long input strings may be rejected or truncated

## How this service works
