## 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 agent-kiosk-30-day-prepaid-api-key-pass-1aeeb3af -d '<json body>'
```

Example prompt: Buy me a 30-day Agent Kiosk API pass for my LangChain agent named 'research-bot' so I can use all the intelligence tools without signing each call separately.

## When to prefer this

Choose this endpoint when you need repeated or high-frequency access to multiple Agent Kiosk tools and want to avoid the overhead of per-call x402 payment signing. It is the best option for LangChain, n8n, Make.com, or any workflow automation context where a stable, long-lived API key is more practical than micropayment-per-request. Prefer this over individual x402 calls when you anticipate more than a few calls within 30 days, making the flat $5 USDC cost more economical.

## Known failure modes

- Payment failure or insufficient USDC balance returns an error and no key is issued
- Invalid or malformed agent_name may be rejected or ignored
- Duplicate purchase creates a new key without extending an existing one
- Network or Vercel infrastructure downtime causes 502/503 responses
- Key issuance service unavailable returns an error with no API key in response
