## 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 simfuse-portugal-500-mb-esim-1-day-prepaid-9cfc0923 -d '<json body>'
```

Example prompt: Buy me a Portugal 500 MB travel eSIM — just 1 — and send the install details to sarah@example.com.

## When to prefer this

Choose this endpoint when a traveller needs immediate mobile data specifically in Portugal for up to 1 day and wants to avoid roaming fees or physical SIM cards. Ideal for AI agents that need to provision eSIMs programmatically without an account or API key, paying per-use in USDC. Use sibling endpoints for other countries or longer data plans.

## Known failure modes

- Payment rejected if USDC balance is insufficient or x402 payment fails
- Invalid quantity (outside 1–20) returns a validation error
- Invalid email format may cause email delivery failure but not block order
- Order status URL temporarily unavailable if provisioning is delayed

## How this service works

Portugal 500 MB: a prepaid travel eSIM with 500 MB of data for 1 day. Buy it when a traveller needs mobile data abroad without a local SIM card or roaming fees. Pay in USDC on Base with x402, no account or API key needed. The installable eSIM (QR code, LPA activation code, one-tap iPhone and Android links) is ready within seconds from order_status_url. Optional JSON body: quantity (1 to 20) and email.

## Output

Returns an order_status_url where the agent or traveller can retrieve the eSIM QR code, LPA activation code, and one-tap install links for iPhone and Android. If an email was provided, the same install details are also sent to that address. The eSIM is ready within seconds of purchase.
