## 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 api-run402-com-27eb596a -d '<json body>'
```

Example prompt: Set my wallet on Run402 to the prototype tier — I want to subscribe now for $0.10 USDC and get access activated.

## When to prefer this

Use this endpoint when you need to activate or renew the entry-level prototype tier on Run402 for $0.10 USDC. Choose this over the hobby tier endpoint when only basic/prototype-level API access is needed and cost minimization is important.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or missing wallet address — returns 400 Bad Request
- Tier already active and not expired — may return idempotent subscribe or renew depending on state
- Network or provider outage — returns 5xx error

## How this service works

Set prototype tier ($0.10 USDC) — auto-detects subscribe/renew/upgrade

## Output

Returns the activated tier name ('prototype'), the action performed (subscribe/renew/upgrade), the wallet address, previous tier (null if new), lease start and expiry timestamps (7-day lease), and remaining allowance in USD micros.
