The WDK Indexer REST API provides fast, reliable access to balances, token transfers, and transaction history across multiple chains.
A blockchain indexer continuously monitors and organizes blockchain transactions, making them instantly searchable through a simple REST API.
Supported Chains and Tokens
The WDK Indexer publishes its current blockchain and token inventory through GET /api/v1/chains. Query this endpoint at runtime instead of copying a static list into your integration because coverage can change independently of the documentation.
The response uses lowercase route keys such as usdt and xaut. Preserve those exact values in API paths. In reader-facing text, label the contract variant deployed on the selected chain—for example, USD₮ on Ethereum and USD₮0 on Arbitrum or Polygon, with the same distinction for XAU₮ and XAU₮0.
