## 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 agentsvc-io-credits-top-up-c3dfc5f9 -d '<json body>'
```

Example prompt: Top up my agentsvc.io credit balance with $1 USDC so I have funds ready to make API calls without paying per request each time.

## When to prefer this

Choose this endpoint when you want to pre-fund an agentsvc.io balance to avoid per-call USDC payments on every individual API request, reducing transaction overhead for high-frequency or batch usage of agentsvc.io's 70 web services.

## Known failure modes

- Insufficient USDC in wallet — payment rejected with 402 error
- Invalid or malformed request body — 400 bad request
- Payment transaction failure on Base or Solana network — timeout or network error
- Duplicate transaction detection — idempotency conflict
- Service unavailable — 503 if agentsvc.io backend is down
