Midnight Indexer Skill

The Midnight Indexer exposes a GraphQL API that indexes everything the chain produces: blocks, transactions, contract actions, and UTXO events. It is the only way to read public on-chain state from a DApp frontend.

  • docs.midnight.network/api-reference/midnight-indexer — official v4 API reference
  • github.com/midnightntwrk/midnight-indexer/blob/v4.0.1/indexer-api/graphql/schema-v4.graphql — authoritative schema
