## 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 x402-farm-20gb-proxy-key-64196c80
```

Example prompt: Buy me a 20GB proxy bandwidth key using USDC on Base — I need it without signing up for an account, just pay and get the key.

## When to prefer this

Choose this endpoint when you need to programmatically provision proxy bandwidth without account registration, prefer paying per-use in USDC on Base via the x402 protocol, and need exactly 20GB of bandwidth. Prefer this over subscription proxy services when operating as an autonomous agent that needs on-demand proxy access with no recurring commitments.

## Known failure modes

- Payment failure: USDC balance insufficient or x402 payment not accepted — returns payment error
- Key already expired or invalid if the provisioned key has a time-limited validity window
- Network error from api.x-402.online resulting in no response
- Quota exhaustion: key may be issued but bandwidth depleted faster than expected if shared infrastructure

## How this service works

Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.

## Output

Returns a JSON object containing the proxy key string (e.g. 'rp1.20.1790000000.xxxx') and the bandwidth amount in gigabytes (gb: 20). The key can then be used to authenticate proxy connections up to 20GB of traffic.
