## 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 agentbit-base64-encode-b0427be4 -d '<json body>'
```

Example prompt: Can you base64 encode the string 'Hello, World!' for me?

## When to prefer this

Choose this endpoint when you need a quick, no-signup, pay-per-call Base64 encoding utility without setting up authentication or API keys — particularly useful in agent workflows where spinning up infrastructure is impractical and micro-payments via x402 are acceptable.

## Known failure modes

- Missing or empty 'input' field — likely returns a 400 or validation error
- Input value too large — may exceed payload limits
- Payment failure via x402 — call not processed if USDC payment is insufficient
- Malformed JSON request body — returns error response
