# Account Queries & Monitoring

> Discover accounts, read APY/TVL, check balances and fees, and monitor withdrawal status — using REST API calls and on-chain reads

The Amplify SDK wraps several API endpoints and on-chain reads behind convenient functions like `getVaultAPY()` and `getWithdrawalRequests()`. When integrating directly, you call these yourself. This section covers every read-only operation the SDK provides, with the raw API calls and contract reads you need.

<Info>
  All API endpoints require an API key passed via the `x-api-key` header.
  Contact [Paxos Labs](mailto:support@paxoslabs.com) to get one. The GraphQL
  endpoint (`POST /graphql`) returns account contract addresses needed for
  integration. See [Account Discovery](/v0.5.2/intro/products/earn/developers/guides/direct-contract/vault-queries/vault-discovery)
  for the full query.
