Does Crossmint have an API?

Yes, Crossmint does have an API, and provides a suite of tools for managing and operating NFTs, including wallet creation, NFT minting, and collection management, and accessible to users without extensive blockchain knowledge. It supports multiple blockchain networks and offers both API and no-code options for a broad range of NFT-related operations. However, if you're looking for an alternative that allows you to integrate not only with Crossmint, but also with 300+ other digital asset exchanges and wallets, consider using Mesh API instead.

About Crossmint

  2. Configure your project by selecting it from the dashboard, going to the "Custom Authentication" tab, and creating a verifier as a Custom Provider. Add the JWKS Endpoint and create custom validations for the provider.
  3. Retrieve the client and verifier IDs by selecting your project from the dashboard, finding the client ID in the "Project Details" tab, and locating the verifier ID for the recently created verifier in the "Custom Authentication" tab.

Errors

Here are the most common API errors for Crossmint API:

  • Not Enough Credits: This error occurs when you run out of API credits. To resolve this, purchase more credits on the billing page in the production environment or request a top-up for the staging environment by emailing support@crossmint.io.
  • Infinite loading on checkout: If you experience an issue with the checkout process, check the Chrome developer console for errors. If the error is unclear, consider asking for help on Stack Overflow using the 'crossmint' tag.
  • ERC20 transfer amount doesn't match totalPrice: This error occurs when the price passed in the totalPrice attribute of the mintConfig does not match the price set in the smart contract. Ensure that the price passed in the totalPrice attribute matches the price set in the contract, converting any decimal places accordingly.
