Blocks

13 endpoints.

• Block Chain Events — GET /api/v1/blocks/{ref}/chain-events
  Fetch EVERY raw pallet-level event in one block (by numeric block_number; event_index ascending), served live from the live-follow hot tier above the decode seam and the chain_events lakehouse at or below it (no static file).
• Block Chain Events By Network — GET /api/v1/{network}/blocks/{ref}/chain-events
  Network-scoped form of /api/v1/blocks/{ref}/chain-events — prefix the route with a network to choose which chain answers it.
• Block Detail — GET /api/v1/blocks/{ref}
  Fetch per-block detail by numeric block_number or 0x block_hash.
• Block Detail By Network — GET /api/v1/{network}/blocks/{ref}
  Network-scoped form of /api/v1/blocks/{ref} — prefix the route with a network to choose which chain answers it.
• Block Events — GET /api/v1/blocks/{ref}/events
  Fetch the ACCOUNT-ATTRIBUTED events in one block (by numeric block_number or 0x block_hash), in natural order; ?limit (<=1000) / ?offset.
• Block Events By Network — GET /api/v1/{network}/blocks/{ref}/events
  Network-scoped form of /api/v1/blocks/{ref}/events — prefix the route with a network to choose which chain answers it.
• Block Extrinsics — GET /api/v1/blocks/{ref}/extrinsics
  Fetch the extrinsics in one block (by numeric block_number or 0x block_hash), in natural order; ?limit (<=100) / ?offset.
• Block Extrinsics By Network — GET /api/v1/{network}/blocks/{ref}/extrinsics
  Network-scoped form of /api/v1/blocks/{ref}/extrinsics — prefix the route with a network to choose which chain answers it.
• Blocks Feed — GET /api/v1/blocks
  Fetch the recent-block feed (newest first) for the block explorer; ?limit (<=100) / ?offset, or ?cursor= for stable keyset paging under head-of-chain inserts (#1851).
• Blocks Feed By Network — GET /api/v1/{network}/blocks
  Network-scoped form of /api/v1/blocks — prefix the route with a network to choose which chain answers it.
• Blocks Summary — GET /api/v1/blocks/summary
  Fetch block-production analytics over recent blocks: inter-block time distribution, extrinsic/event throughput, block-author decentralization (concentration over each author's block count), and the spec-version spread.
• Blocks Summary By Network — GET /api/v1/{network}/blocks/summary
  Network-scoped form of /api/v1/blocks/summary — prefix the route with a network to choose which chain answers it.
• Runtime Versions — GET /api/v1/runtime
  Fetch the spec-version transition timeline — the earliest known block at each distinct runtime spec_version, ascending by block_number.
