  ## About 0xAPI

  0xAPI is organized into several distinct services, each catering to specific data needs with consistent, blockchain-agnostic response schemas.

  ## Core capabilities

  | **Feature**         | **Description**                                                                                                                                                                   | **Use cases**                                                                                      |
  | ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------- |
  | **Token API**       | Retrieve detailed information on fungible tokens (ex. ERC-20). Fetch wallet balances, token transfers, daily portfolio snapshots, approvals, holder lists, and live token prices. | Power wallets, portfolio dashboards, token-gated apps, and analytics tools for on-chain assets.    |
  | **NFT API**         | Access complete NFT data, including all NFTs owned by a wallet or within a collection. Get detailed collection metadata, traits, and rarity statistics.                           | Build NFT galleries, marketplaces, collection analytics, or portfolio trackers.                    |
  | **Transaction API** | Query detailed transaction data. Retrieve all transactions for a wallet, look up a specific transaction by hash, or get a full summary of a wallet’s on-chain activity.           | Ideal for transaction histories, accounting tools, on-chain analytics, and activity monitoring.    |
  | **ENS API**         | Resolve ENS domains to wallet addresses or perform reverse lookups to find ENS names linked to a wallet.                                                                          | Build explorers, alert systems, or real-time dashboards that track specific contract interactions. |
