Check Token Support

Check whether Crossmint Checkout supports a specific token before you integrate it

​

Call the Supported Tokens API

Before you integrate a token into your checkout, verify support with the Supported Tokens API:

• Endpoint: https://staging.crossmint.com/api/v1-alpha2/tokens/:tokenLocator (staging) or https://www.crossmint.com/api/v1-alpha2/tokens/:tokenLocator (production)
• Method: GET
• Authentication: a server-side or client-side API key with the orders.create scope

The tokenLocator follows the format network:tokenAddress — for example solana:6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN. On staging, use the XMEME test token: solana:7EivYFyNfgGj8xbUymR7J4LuxUHLKRzpLaERHLvi7Dgu.

Production memecoin tokens will not work in the staging environment.

const tokenLocator = "solana:7EivYFyNfgGj8xbUymR7J4LuxUHLKRzpLaERHLvi7Dgu"; // XMEME test token on staging

const response = await fetch(`https://staging.crossmint.com/api/v1-alpha2/tokens/${tokenLocator}`, {
    method: "GET",
    headers: {
        "x-api-key": "<your-server-api-key>",
        "Content-Type": "application/json",
    },
});

const tokenSupport = await response.json();

Read the Response

A successful response tells you whether the token can be sold and which payment features are enabled:

{
    "token": "solana:6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN",
    "available": true,
    "features": {
        "creditCardPayment": true
    }
}

Check available and the features you need before showing the token or creating an order — transactions for unsupported tokens fail. For frequently accessed tokens, cache the result for a short period (for example 1 hour); the API is rate-limited to 50 requests per second.

To request support for an unsupported token, contact the support team.
