In the rapidly evolving world of Web3 and blockchain technology, accessing accurate and comprehensive NFT data is essential for developers, marketplaces, and wallet services. Whether you're building a decentralized application (dApp), integrating NFT functionality into your platform, or analyzing digital asset trends, having reliable access to NFT metadata, token details, contract information, and collection attributes is crucial.
This guide dives deep into a robust NFT API endpoint that enables seamless retrieval of NFT details across supported blockchains. With this tool, you can unlock rich metadata such as token names, images, animations, attributes, and associated smart contract and collection data — all through a single, efficient request.
Core Features of the NFT Detail Retrieval API
The GET /api/v5/mktplace/nft/asset/detail endpoint allows developers to fetch complete information about any NFT using just three key parameters: chain name, contract address, and token ID. This makes it an ideal solution for applications requiring dynamic NFT visualization, portfolio tracking, or marketplace listings.

Supported Blockchains
Before making a request, ensure the target blockchain is supported. The API works across multiple chains, including Ethereum, Polygon, OKC, and others. For the full list of supported networks, refer to official documentation on multi-chain compatibility in Web3 infrastructure.
How to Use the NFT Detail Endpoint
To retrieve detailed information about an NFT, send a GET request to the following URL:
https://web3.okx.com/api/v5/mktplace/nft/asset/detailRequired Request Parameters
Each request must include the following parameters:
- chain (String, required): The name of the blockchain network where the NFT resides.
- contractAddress (String, required): The smart contract address of the NFT collection. Must be a valid hexadecimal address.
- tokenId (String, required): The unique identifier of the NFT within its collection.
These inputs allow the API to precisely locate and return the requested asset’s metadata from the appropriate chain.
Understanding the Response Structure
Upon successful execution, the API returns a structured JSON response containing comprehensive details about the NFT. Below are the key fields included in the response:
Basic Token Information
- name: The display name of the NFT.
- tokenId: The unique token ID within the contract.
- tokenUri: The URI pointing to the NFT's metadata file (usually hosted on IPFS or similar decentralized storage).
- image: Direct URL to the primary image asset of the NFT.
- imagePreviewUrl: A lower-resolution preview version of the image, optimized for faster loading.
- imageThumbnailUrl: A small thumbnail-sized version of the image for compact UI displays.
- animationUrl: If applicable, the URL to audio, video, or interactive media associated with the NFT.
Advanced Metadata and Contextual Data
- attributes: An object containing trait-based metadata such as rarity scores, character features, or game stats. Each attribute follows a standardized model including trait_type and value, enabling consistent parsing across collections.
- assetContracts: Detailed information about the smart contract behind the NFT, including contract type (ERC-721 or ERC-1155), creator address, and deployment details.
- collection: Metadata about the broader NFT collection, such as collection name, description, floor price (if available), and social links.
This depth of data empowers developers to build rich user experiences — from displaying dynamic galleries to powering analytics dashboards.

Practical Use Cases
1. NFT Marketplace Integration
Marketplace platforms can use this API to dynamically load NFT listings, ensuring accurate previews, attribute breakdowns, and provenance verification without relying on third-party indexing delays.
2. Wallet Applications
Wallets offering NFT support can enhance user experience by showing high-quality images, previews, and detailed trait information directly within the interface.
3. Analytics & Research Tools
Data aggregators and analytics platforms benefit from standardized responses that simplify large-scale scraping and analysis of NFT traits, pricing trends, and collection performance.
4. Game Development & Metaverse Platforms
For games leveraging NFTs as in-game assets, retrieving animation URLs and attribute data enables real-time rendering and functionality based on item properties.
Frequently Asked Questions
Q: Can I use this API to retrieve metadata for both ERC-721 and ERC-1155 tokens?
A: Yes, the API supports both major NFT standards across all listed blockchains. It automatically detects the contract type and returns appropriately formatted data.
Q: Is there rate limiting on this endpoint?
A: Yes, to maintain service stability and fairness, rate limits apply based on your authentication tier. Developers are encouraged to cache responses when possible to reduce redundant calls.
Q: What happens if an NFT has no image or animation URL?
A: If certain media fields are missing from the original metadata, those keys will either be null or omitted from the response. Always check for their presence before rendering.
Q: How up-to-date is the data returned by this API?
A: The system indexes blockchain events in near real-time. Metadata is refreshed upon detection of transfers or updates, ensuring high accuracy.
Q: Does this API support metadata fallback mechanisms like off-chain backups?
A: Yes, in cases where tokenURI points to unavailable resources, the service attempts to resolve through decentralized alternatives like IPFS gateways or stored snapshots.
Q: Can I retrieve metadata for multiple NFTs at once?
A: While this specific endpoint targets individual tokens, batch queries can be achieved via parallel requests. Consider using asynchronous processing for optimal performance.
Why Choose This NFT API?
With growing demand for interoperable Web3 tools, this endpoint stands out due to its:
- Multi-chain support: Operates across major EVM-compatible networks.
- Standardized schema: Ensures predictable output regardless of source chain or contract.
- High availability: Built for production-grade applications with low-latency responses.
- Developer-first design: Clear documentation and consistent error handling streamline integration.
Whether you're launching a new dApp or enhancing an existing platform, access to reliable NFT data is non-negotiable.
