面向开发人员的最佳加密钱包数据 API (2026)

TL;DR: Which Crypto Wallet Data API Is the Best? CoinGecko API supports most wallet-data use cases, combining wallet and market data under the same API, flat per-request credit charge regardless of the number of networks queried, and broadest network coverage.

supports most wallet-data use cases, combining wallet and market data under the same API, flat per-request credit charge regardless of the number of networks queried, and broadest network coverage. Specialized providers serve specific needs, including Moralis for pre-categorized activity feeds, Alchemy for free prototyping, DeBank for normalized DeFi position data, and CoinStats for DeFi data alongside standard wallet balances.

Portfolio trackers, tax tools, DeFi dashboards, and AI trading agents rely on wallet data to understand what a wallet holds and how it has been used. A wallet data API turns a wallet address into structured data, so you can work with this information without pulling and decoding raw blockchain logs yourself.

Wallet data APIs read activity from existing wallets. If your application also needs to generate wallets, sign transactions, or manage private keys, you can pair a wallet data API with a wallet-as-a-service provider such as Privy, Turnkey, or Fireblocks.

This guide compares five wallet data APIs: CoinGecko, Moralis, Alchemy, DeBank, and CoinStats. We looked at chain coverage, key capabilities, limitations, pricing and usage.

How to Choose a Crypto Wallet Data API

Chain coverage

The breadth of network coverage and whether the provider supports the chains your application requires.

Balances and token holdings

Whether you can filter out spam and low-value tokens, sort by value, and paginate through wallets holding hundreds of tokens instead of receiving everything unsorted in a single response.

Transaction and transfer history

How activity is returned. Some providers tag and categorize events such as buys, deposits, and swaps, while others return raw logs that require interpretation.

Historical data

How far back wallet value and activity can be accessed.

PnL and cost basis

Whether profit and loss is calculated and which cost-basis method is used, since different methods can produce different results. Providers may use static average cost, moving average cost, or per-lot methods such as FIFO or HIFO.

Pricing, usage, and rate limits

Consider the cost at the expected usage, including how pricing changes beyond the plan quota. Rate limits determine how many requests can be made per second and how quickly data can be pulled across multiple wallets.

AI agent and MCP support

Whether AI agents or MCP-based tools can query wallet data directly, which is relevant for autonomous applications.

Wallet Data APIs at a Glance

CoinGecko API provides unified wallet and market data with flat, per-request pricing across 250+ networks. Other providers offer different capabilities, including pre-categorized activity feeds, free usage for prototyping, and detailed DeFi position data for specific use cases.

Best Crypto Wallet Data APIs

CoinGecko API: Broadest Chain Coverage, Unified Wallet Data, and Efficient Pricing

CoinGecko is the most widely used crypto market data API, trusted by platforms including Coinbase, Kraken, and Etherscan. Its Onchain Wallet endpoints cover wallet balances, trade history, transfers, and PnL, with support for 250+ chains, including Ethereum, Solana, Robinhood, and Base.

Pros

Broadest trade and PnL coverage: Trade history and PnL extend across 250+ chains, allowing multi-chain wallet activity to be accessed through a single provider.

Trade history and PnL extend across 250+ chains, allowing multi-chain wallet activity to be accessed through a single provider. Flat pricing: Each API request costs 1 credit, regardless of the number of networks queried, so querying more networks within the same chain type does not increase credit usage.

Each API request costs 1 credit, regardless of the number of networks queried, so querying more networks within the same chain type does not increase credit usage. Real-time, filterable wallet data: Trade and transfer data is returned without a cache delay, while balance queries support minimum USD value filtering, sorting, and pagination to exclude dust and spam tokens.

Trade and transfer data is returned without a cache delay, while balance queries support minimum USD value filtering, sorting, and pagination to exclude dust and spam tokens. Built-in PnL: Provides realized and unrealized profit and loss without requiring separate PnL calculations.

Provides realized and unrealized profit and loss without requiring separate PnL calculations. Official AI tooling: AI integrations, SDKs, MCP, CLI, Agent Skills, and x402 pay-per-use access for querying crypto data through AI applications.

AI integrations, SDKs, MCP, CLI, Agent Skills, and x402 pay-per-use access for querying crypto data through AI applications. Unified data access: Wallet data alongside comprehensive price and market data are available through the same API.

Cons

No historical balance chart: The balance endpoint provides current holdings. Historical holdings can be reconstructed from trade and transfer data, but there is no built-in chart for historical holdings.

The balance endpoint provides current holdings. Historical holdings can be reconstructed from trade and transfer data, but there is no built-in chart for historical holdings. Limited PnL history: PnL is provided as lifetime realized and unrealized totals, without built-in daily or monthly breakdowns. Period-based PnL can still be calculated server-side using raw trade data.

PnL is provided as lifetime realized and unrealized totals, without built-in daily or monthly breakdowns. Period-based PnL can still be calculated server-side using raw trade data. Paid wallet access: CoinGecko API provides a free Demo API plan. However, its wallet endpoints are exclusively available on the $129/mo Analyst plan and above.

Moralis API: Best for Pre-Categorized Wallet Activity

Moralis API provides wallet balances, transaction history, token holdings, and portfolio data across 28 EVM chains, with Solana and Bitcoin supported through dedicated wallet APIs.
