## 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 treza-labs-credits-top-up-via-x402-db70ba63 -d '<json body>'
```

Example prompt: Add $5 of prepaid credits to my Treza Labs account — use my API key to identify which account to top up.

## When to prefer this

Use this endpoint when you need to programmatically top up a Treza Labs prepaid credit balance in exactly $5.00 increments via x402 USDC micropayment. It is the only endpoint for adding credits to Treza accounts; prefer it over manual top-up flows when automating credit maintenance, building self-funding agent pipelines, or when your agent detects a low-balance condition on a Treza account.

## Known failure modes

- x402 payment failure — insufficient USDC balance in payment wallet
- Authentication failure — invalid, expired, or missing bearer token
- Account not found — authenticated identity does not resolve to a valid Treza account
- Duplicate payment rejection — same payment reference submitted twice
- Network or gateway timeout during payment processing

## How this service works

Top up a Treza prepaid credit balance by $5.00 via x402. Authenticate with a Treza bearer (API key, OAuth token, or session) to choose the account credited.

## Output

A confirmation that $5.00 USD in prepaid credits has been successfully added to the authenticated Treza account, along with the updated balance or transaction details.
