In the dynamic world of Web3 and blockchain technology, accessing accurate and reliable token price data is crucial for developers, traders, and enthusiasts. Comprehensive token prices refer to calculated asset valuations derived from multiple third-party data sources, providing a more robust and aggregated market view.
This method of price calculation supports a wide range of digital assets, including native chain coins, standard tokens, and various Bitcoin-based inscription tokens. Understanding how to access this data programmatically is essential for building sophisticated Web3 applications.
What Are Comprehensive Token Prices?
A comprehensive token price is not a single exchange quote but a synthesized value. It is computed by aggregating price data from numerous reputable third-party providers. This approach minimizes the impact of anomalies or liquidity issues on any single platform, offering a more stable and representative market price.
This data is particularly valuable for:
- Portfolio valuation applications
- Decentralized finance (DeFi) protocols requiring accurate pricing for lending/borrowing
- Trading algorithms and analytical tools
- Real-time dashboard displays
Supported Digital Assets
The comprehensive pricing system covers diverse digital asset types across multiple blockchain environments:
Mainnet Coins and Standard Tokens
This includes native cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH), along with standard token implementations such as ERC-20, BEP-20, and other network-specific token standards.
Bitcoin Inscription Tokens
The system also supports various inscription token standards on the Bitcoin network:
- BRC-20 tokens: A token standard utilizing the Bitcoin Ordinals protocol
- Runes tokens: Another emerging standard within the Bitcoin ecosystem
- ARC-20 tokens: Assets issued on the Bitcoin network using the Atomicals protocol
- SRC-20 tokens: Tokens based on the Stamps protocol for Bitcoin
Fractal Bitcoin Tokens
Additionally, the pricing system includes support for BRC-20 inscription tokens on the Fractal Bitcoin network, an innovative extension of the Bitcoin ecosystem.

API Integration for Token Prices
Developers can access comprehensive token pricing data through a well-structured API endpoint designed for efficiency and reliability.
API Request Structure
The primary endpoint for retrieving comprehensive token prices uses a POST request method. This allows for batch processing of multiple token queries in a single API call, significantly reducing the number of requests needed for applications tracking numerous assets.
Endpoint: https://web3.okx.com/api/v5/wallet/token/current-price
Essential Request Parameters
Successful API requests require two critical parameters:
Chain Identifier (chainIndex)
This parameter specifies the blockchain network from which to retrieve price data. Each supported blockchain has a unique identifier that must be used in requests.
Token Address (tokenAddress)
This parameter identifies the specific digital asset being queried and accepts different formats depending on the asset type:
- For native chain coins: Use an empty string (
"") - For standard tokens: Use the token's contract address
- For inscription tokens: Use specific formatting conventions based on the token standard
Batch Processing Capabilities
The API supports批量查询 (batch queries), allowing developers to request prices for up to 100 different tokens in a single API call. This significantly improves efficiency for applications that need to monitor multiple assets simultaneously, reducing both API call volume and potential rate limiting issues.
Working with Inscription Tokens
Inscription tokens require specific formatting for accurate price queries. Here's how to structure requests for different inscription standards:
FBRC-20 Tokens
Use the format: fbtc_fbrc20_name (e.g., fbtc_fbrc20_babymusk)
BRC-20 Tokens
Use the format: btc-brc20-tick(name) (e.g., btc-brc20-ordi)
Runes Tokens
Use the format: btc-runesMain-tickId (e.g., btc-runesMain-840000:2)
SRC-20 Tokens
Use the format: btc-src20-name (e.g., btc-src20-utxo)
Proper formatting ensures accurate price retrieval for these specialized digital assets.
API Response Data
The API returns a structured JSON response containing essential price information:
Price Data
The current token price represented in United States dollars (USD), providing a standardized valuation metric for comparative analysis.
Timestamp Information
A precise timestamp indicating when the price was calculated, represented as a Unix timestamp in milliseconds. This allows developers to understand the freshness of the data and implement appropriate caching strategies.
Asset Identification
The response includes both the chain identifier and token address, ensuring clear correlation between request and response data, which is particularly valuable when making batch requests for multiple assets.

Implementation Best Practices
When integrating comprehensive price data into your applications, consider these implementation strategies:
Error Handling
Implement robust error handling to manage API rate limits, network timeouts, and unexpected response formats. Include fallback mechanisms where appropriate.
Data Caching
Consider caching price data locally to reduce API calls and improve application responsiveness, while being mindful of data freshness requirements for your specific use case.
Batch Optimization
When tracking multiple assets, maximize the batch query capability (up to 100 tokens per request) to minimize total API calls and improve efficiency.
Frequently Asked Questions
What is the advantage of comprehensive pricing over single-exchange data?
Comprehensive pricing aggregates data from multiple sources, reducing the impact of temporary price anomalies, low liquidity on individual exchanges, or potential manipulation attempts. This provides a more stable and representative market price.
How frequently are the comprehensive prices updated?
The pricing data is updated in real-time as new information becomes available from the aggregated data sources. The exact timestamp of each price point is included in the API response for reference.
Can I retrieve historical price data through this API?
The current endpoint provides only the most recent price information. For historical data, you would need to implement your own storage solution or explore additional API endpoints that might offer historical price information.
What happens if I request a token that isn't supported?
The API will typically return an error or null value for unsupported tokens. It's important to implement proper error handling in your code to manage these scenarios gracefully.
Is there a rate limit for API requests?
Most API providers implement rate limiting to ensure fair usage. Check the specific documentation for your API provider to understand the exact limits and implement appropriate request throttling in your application.
How do I determine the correct chainIndex for different blockchains?
The chainIndex values are specific to each API provider. Consult your provider's documentation for a complete list of supported blockchains and their corresponding identifiers.
Conclusion
Comprehensive token pricing provides a robust foundation for Web3 applications requiring accurate digital asset valuation. By aggregating data from multiple sources and supporting diverse asset types including emerging inscription tokens, this approach offers developers reliable pricing information essential for building sophisticated blockchain applications.
The API-based access method with batch processing capabilities enables efficient integration into trading systems, portfolio trackers, DeFi protocols, and analytical tools. As the Web3 ecosystem continues to evolve, accessing reliable comprehensive price data will remain a critical component of successful blockchain applications.
