## 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 vibes-coded-agent-usage-key-management-api-3e37a9c0 -d '<json body>'
```

Example prompt: Show me my current Vibes-Coded usage — which skills I've called the most, how many credits I have left, and whether any of my keys are about to expire.

## When to prefer this

Use this endpoint when an agent needs to audit its own Vibes-Coded account state — checking key validity, remaining credits, spending patterns, or deciding whether to fund, renew, or revoke access — rather than initiating a new skill call or purchasing a service.

## Known failure modes

- Invalid or missing owner_key returns an authentication error
- Unknown agent identifier returns an empty or 404 response
- HTTP 402 returned if the call itself is unpaid (requires USDC payment via x402 protocol)
- Stale or expired session may return outdated balance data
- Rate limiting or network errors may result in 5xx responses

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

Returns a JSON object containing all API keys (paid and trial) with call counts, balances in cents, expiry timestamps, the top-spending skill slugs with call and cost breakdowns, total calls, total balance, and recommended next actions such as funding, day-pass purchase, or key revocation.
