Blocks

Query block data by height or get the latest block

Blocks

Retrieve block headers, transaction lists, and consensus metadata for any block on XYZ Chain.

Get Latest Block

Returns the most recently finalized block.

curl http://67.205.164.156:1317/cosmos/base/tendermint/v1beta1/blocks/latest

Response

{
  "block_id": {
    "hash": "A1B2C3D4...",
    "part_set_header": {
      "total": 1,
      "hash": "E5F6G7H8..."
    }
  },
  "block": {
    "header": {
      "chain_id": "xyz-1",
      "height": "152340",
      "time": "2026-02-19T10:00:00.000Z",
      "proposer_address": "ABC123..."
    },
    "data": {
      "txs": ["base64-encoded-tx-1", "base64-encoded-tx-2"]
    },
    "last_commit": {
      "height": "152339",
      "signatures": [...]
    }
  }
}

Key Fields

Field	Description
block.header.chain_id	Chain identifier (xyz-1 for mainnet)
block.header.height	Block number as a string
block.header.time	Block timestamp in RFC 3339 format
block.header.proposer_address	Hex-encoded address of the validator that proposed this block
block.data.txs	Array of base64-encoded transactions included in this block
block.last_commit.signatures	Validator signatures from the previous block’s commit

Get Block by Height

Retrieve a specific block by its height.

curl http://67.205.164.156:1317/cosmos/base/tendermint/v1beta1/blocks/152340

The response format is identical to the latest block endpoint.

Errors

Case	Response
Height not yet reached	400 — block height is ahead of the chain
Height = 0	400 — invalid height
Negative height	400 — invalid argument

Useful Patterns

Check Current Block Height

curl -s http://67.205.164.156:1317/cosmos/base/tendermint/v1beta1/blocks/latest \
  | jq '.block.header.height'

Get Block Timestamp

curl -s http://67.205.164.156:1317/cosmos/base/tendermint/v1beta1/blocks/152340 \
  | jq '.block.header.time'

Count Transactions in a Block

curl -s http://67.205.164.156:1317/cosmos/base/tendermint/v1beta1/blocks/152340 \
  | jq '.block.data.txs | length'
