## 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 nordforge-encode-base64-base64url-hex-encoder-decoder-0ac7cc9f -d '<json body>'
```

Example prompt: Can you base64-encode the string 'Hello, World!' using the Nordforge encode tool?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call encoding or decoding operation without provisioning any API keys or subscriptions — ideal for agents that need occasional Base64, Base64URL, or Hex conversion as part of a workflow and want to pay only for what they use via USDC on Base.

## Known failure modes

- Missing required 'text' field returns a validation error
- Invalid 'op' enum value (not base64, base64url, or hex) returns a bad request error
- Invalid 'direction' enum value returns a bad request error
- Attempting to decode malformed/invalid encoded input may return a decoding error
- Payment failure via x402 prevents the call from completing

## How this service works

Pay-per-call hashing, encoding, ping, URL→markdown and JSON fetch. USDC on Base via x402.

## Output

Returns the encoded or decoded version of the input string in the requested format (base64, base64url, or hex), depending on the direction specified.
