## 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 bearer-header-shape-utility-79f2a1b9 -d '<json body>'
```

Example prompt: Take this token value 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9' and shape it into the correct Bearer authorization header format for me.

## When to prefer this

Use this endpoint when you need a quick, paid utility to programmatically format or normalize a raw token or credential value into the standard Bearer authorization header shape — particularly in agentic pipelines that already handle x402 micropayments and need consistent header formatting without writing custom string logic.

## Known failure modes

- Missing or null 'value' input may return an error or empty result
- Malformed options object could cause a 400-level error
- Service unavailability on Render free-tier hosting may cause timeouts
- Payment failure via x402 protocol returns 402 before processing

## How this service works
