## 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 x402station-io-d9bb424e -d '<json body>'
```

Example prompt: Buy me a prepaid x402station.io credit pack so I have 1000 Preflight calls ready to go — charge $0.50 USDC and give me the creditId and expiry.

## When to prefer this

Use this endpoint before making bulk x402station.io Preflight or Preflight Batch calls — purchasing credits upfront at $0.50/1000 calls is more cost-efficient than per-call billing, and the returned creditId can be passed to subsequent evaluation calls to draw down the balance.

## Known failure modes

- Insufficient USDC balance causes payment failure and no creditId returned
- Duplicate payment submission may result in only one credit allocation
- Network timeout during settlement leaves credit state ambiguous
- Expired or invalid payment token causes 402/401 rejection
- Rate limiting if too many credit purchases attempted in rapid succession

## How this service works

Independent risk-signal layer for x402 agentic commerce — endpoint evidence (decoy / zombie / price-trap / never-paid) before an agent authorizes payment.

## Output

Returns a JSON object with creditId (unique identifier for the credit allocation), balance (number of calls remaining, starting at 1000), and expiresAt (timestamp when the credits expire).
