## 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 patternfetch-com-credit-top-up-a498a57b -d '<json body>'
```

Example prompt: Top up my patternfetch.com account with 1 USDC so I have $1 credit to use — go ahead and process the payment now.

## When to prefer this

Use this endpoint specifically when an agent needs to replenish patternfetch.com API credits and has USDC available via the x402 payment protocol. This is the canonical top-up endpoint for patternfetch and is the only way to add credit to a patternfetch account programmatically.

## Known failure modes

- Insufficient USDC balance — payment rejected, credit not added
- Invalid or missing x402 payment header — 402 Payment Required response
- Network timeout during payment processing — credit status unknown
- Duplicate payment attempt — may be rejected or result in double credit depending on server logic
- Payment processor unavailability — service temporarily down
