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'
