Developers · REST API v1

Issue cards from your own code

Create, fund, freeze and close virtual Visa and Mastercard cards over HTTPS. Requests are JSON, authenticated with a secret key, and draw on the same USDT balance you top up with crypto.

Base URL: https://cardglee.com/api/v1Authentication: Bearer sk_live_…Format: JSONWebhooks: HMAC-SHA256

Introduction

The API does what the dashboard does, from your server. Every card you issue and every load you make is paid from your account balance, which you fund with crypto deposits and which is always held in USDT.

Amounts are in US dollars with two decimals. Timestamps are ISO 8601 in UTC. List endpoints are paginated with page and per_page.

Card endpoints go live with card issuing in Phase 2. Wallet balance and BIN list endpoints are live now.

Authentication

Send your secret key as a Bearer token in the Authorization header of every request. Keys start with sk_live_ and are generated in your dashboard under API access.

Headers
Authorization: Bearer sk_live_your_api_key
Content-Type: application/json
X-Idempotency-Key: 7c1e2f0a-retry-safe

A new key answers 403 until the account is ready. Confirm your email, make a first deposit, then ask support to enable API access for the account.

Errors

Limits are counted per API key. Over a limit you get a 429— wait and retry with exponential backoff.

Cards

Each card has its own balance, limits and lifecycle, so one campaign, client or subscription never touches another.
