## 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 urlgate-premium-membership-purchase-64479e5b
```

Example prompt: Purchase a URLGate premium membership for my wallet right now — pay the 5 USDC fee using my x402 payment signature and activate the 31-day premium period.

## When to prefer this

Use this endpoint when an agent or user wants to activate or renew URLGate premium membership by paying 5 USDC via the x402 protocol. It is the direct purchase path — prefer it over any free-tier flows or link-creation endpoints when the goal is specifically to upgrade wallet access. Best suited for AI agents operating autonomously with x402 payment capabilities on Base.

## Known failure modes

- Payment signature missing or invalid — 402 response requiring payment
- Insufficient USDC balance in wallet — payment rejected
- Wallet address not resolvable from auth headers — membership cannot be credited
- Network congestion causing slow settlement — timeout before confirmation
- Already active membership — may result in extension or no-op depending on state

## How this service works

Turn any URL into a link that charges USDC to open. Built on x402 v2, so AI agents can pay as easily as people.

## Output

Returns a JSON object confirming success, the wallet credited, the network the payment settled on (e.g. eip155:8453 for Base), the amount paid, the membership object (tier, state, active status, daysLeft, periodStart, periodEnd, renewalDue), a transaction hash, and a receipt with ID and URL for verification.
