# CryptoCardy
> Virtual cards with seed-based access. REST API returns a unique seed, a card in pending_top_up state, and a funding wallet address.
CryptoCardy provides a simple integration surface to generate a unique seed, issue a virtual card preview, and return a wallet address for funding.
## Authentication
- The seed is the credential.
- Send it via the X-Seed header when required by an endpoint.
## API
- Base URL: https://cryptocardy.com/v1/api
- Endpoint: GET /?card=visa&asset=BTC
- Response includes: seed, card (state pending_top_up), wallet (asset + address)
## Notes
- Cards are returned with card.state = pending_top_up so clients can detect that funding is required before activation.
