## 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 ssdf-lender-overlay-fc983578
```

Example prompt: Buy me the SSDF lender overlay from the SSDF digital store — pay the $79 USDC price and get back my Passport and fulfillment token.

## When to prefer this

Choose this endpoint when an agent or user specifically needs to purchase the SSDF lender-overlay digital product, receive an on-chain Passport, and obtain a fulfillment token — particularly in agentic workflows that support x402 micropayment protocol and USDC settlement on Base. It is the only endpoint for this specific SKU.

## Known failure modes

- Insufficient USDC balance — payment fails and ok returns false
- x402 payment header missing or malformed — 402 response with no fulfillment issued
- Network or Base chain congestion causing settlement delay
- Invalid or expired payment — Passport not minted, no fulfillment token returned
- Rate limiting or SKU out of stock returning an error response

## How this service works

SSDF INC digital store. Priced in USD, settled in USDC on Base through Coinbase Business. Humans and agents buy the same SKU. Every settlement mints a Passport.

## Output

Returns a JSON object with: ok (true if purchase succeeded), sku (the purchased SKU string 'ssdf-lender-overlay'), passport (a minted Passport ID on-chain), and fulfillment (a URL/token path to retrieve the actual digital product).
