Data API

A hosted indexing service that exposes queryable blockchain state for the Tempo payment chain. It sits between raw RPC and application code, turning low-level storage reads into structured, paginated REST endpoints.

What it covers

The API indexes Tempo's on-chain state and exposes it as filterable, paginated endpoints. The current surface includes:

• Tokens — metadata, supply, and holder lists for any TIP-20 token on the network.
• Wallet balances — all token balances for a given address in a single call, with optional token metadata expansion.
• Transfer history — paginated transfer activity for any wallet, filterable by token, direction, and date range.
• Allowances — token spending allowances between accounts, queryable by owner or spender.
• Access keys — account key configuration and permissions.

How it works

The indexer follows the chain head, decoding token policies, TIP-20 transfers, fee abstraction events, and memo-tagged payments into normalized tables. Queries run against the indexed state, not against the node directly, so response times stay consistent regardless of chain load.

All endpoints are authenticated with an API key and scoped to a single chain parameter (currently moderato, Tempo's active testnet).
