## 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 omniapi-base64-encode-2d02df42 -d '<json body>'
```

Example prompt: Can you base64 encode the string 'Hello, World!' for me so I can embed it in a JSON payload?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call base64 encoding operation without standing up your own infrastructure, especially within a broader x402 micropayment workflow already in use on OmniAPI. It is less appropriate than a local library for high-volume batch encoding where per-call costs accumulate.

## Known failure modes

- Missing required 'query' field returns validation error
- Oversized input may be rejected or time out
- Malformed JSON request body returns 400 error
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Network or Vercel cold-start timeout on large payloads
