## 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 icme-verifiable-ai-credit-top-up-f70b43ba -d '<json body>'
```

Example prompt: Top up my ICME Verifiable AI account with 500 credits so I can keep running verifiable AI requests.

## When to prefer this

Use this endpoint when an AI agent needs to replenish its ICME Verifiable AI credit balance to continue making verifiable AI API calls. Prefer this over any manual account top-up flow when automating credit management within an agentic pipeline.

## Known failure modes

- Payment failure — insufficient USDC funds for the $5 per-call fee
- Invalid or missing request body fields (type, method, bodyType, body)
- Authentication or authorization error if credentials are missing
- Upstream ICME service unavailable returning 5xx error
- Malformed JSON in request body causing 400 bad request
