## 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 delx-commerce-environment-key-validator-2f8fc993 -d '<json body>'
```

Example prompt: Can you check whether this key string is valid and properly formatted — it's supposed to be my X402_PRIVATE_KEY: 'abc123xyz789qrst'?

## When to prefer this

Use this endpoint when an AI agent or automation workflow needs to programmatically verify that an environment key string is correctly formatted before injecting it into a configuration or downstream API call. It is particularly suited for agent pipelines that rotate or receive keys dynamically and need lightweight, cheap ($0.001 USDC) validation without standing up their own key-format logic.

## Known failure modes

- Empty or missing key field returns validation failure
- Malformed or too-short key string returns valid=false
- Network or payment failure (x402 USDC micropayment not processed) blocks the call
- Invalid JSON body returns 400-level error

## How this service works

## Output

Returns a JSON object indicating the key name (e.g. 'X402_PRIVATE_KEY'), whether the key is valid (boolean), its character length, and the schema identifier ('delx/util-env-key-validate/v1') that was used to validate it.
