Does OpensSea have an API?

OpenSea offers a public API, providing access to ERC721 and ERC1155 token metadata, events, collections, listings, and more. However, an alternative is to use Mesh, which has built direct integration with OpenSea and 300+ other digital asset exchanges and wallets.

How to access OpenSea’s public API

OpenSea is a popular marketplace for NFTs, offering a powerful API that allows developers to build new experiences using NFTs and access marketplace data. The API provides endpoints to fetch ERC721 and ERC1155 token metadata, as well as other core elements of the marketplace such as events, collections, listings, and offers. To access OpenSea's public API, users need to request an API key. More information can be found in the API Overview documentation.

Alternatively, developers can use Mesh to access digital assets from various sources, including OpenSea. Mesh APIs allow client applications to connect users to their accounts across brokerages, centralized exchanges, self-custody wallets, and NFT marketplaces. To get started with Mesh, follow the instructions in the Quickstart Guide with Link SDKs.

What does OpenSea’s API documentation look like?

The OpenSea API enables developers to create new experiences using NFTs (Non-Fungible Tokens) and access the OpenSea marketplace data. With a variety of endpoints, developers can fetch ERC721 and ERC1155 token metadata, events, collections, listings, and offers. The API is provided free of charge, but requires attribution to OpenSea and an API key for production use. The API Overview page also includes a FAQ section addressing topics such as creating listings, obtaining an API key, the availability of an SDK, and contacting OpenSea about the API.

OpenSea API errors and troubleshooting

When working with the OpenSea API, developers may encounter errors that can disrupt the functionality of their applications. Understanding common errors and their solutions is crucial for a seamless development experience.

Although the API Overview does not provide specific error codes, developers should be aware of potential issues such as rate-limiting and the requirement of an API key for production use. To troubleshoot these errors, ensure you have a valid API key and monitor your application's request rate to stay within the allowed limits.

For Mesh-specific errors, users can check the Mesh Status Page to identify any ongoing issues or incidents that may be affecting the platform.
