Parameters

Optional parameters (11)

network string

Network. One of finney, kusanagi, nakamoto. Default: finney.

block_number integer (int32)

Specific block number (exact match).

block_start integer (int32)

Block range start (inclusive lower bound).

block_end integer (int32)

Block range end (inclusive upper bound).

timestamp_start integer (int64)

Timestamp range start, Unix seconds (inclusive lower bound).

timestamp_end integer (int64)

Timestamp range end, Unix seconds (inclusive upper bound).

hash string

Exact block hash (0x-prefixed hex).

page integer (int32)

Page number (1-indexed). Default: 1. Bounded window: (page − 1) × limit must be below 1,000,000. Deep OFFSET paging is linear in the offset, so an uncapped page lets one request scan tens of millions of rows; a page past the window is rejected with a 400. Reach deeper history with this endpoint's range filters (block_start/block_end, timestamp_start/timestamp_end) rather than a larger page.

limit integer (int32)

Results per page. Default: 50. Max: 200.

order_by string

Column to order by. Only timestamp is supported.

order_dir string

Sort direction. Default: desc.

Request

GET https://api.taostats.io/v1/blocks

Deep `OFFSET` paging is linear in the offset, so an uncapped `page` lets one request scan tens of millions of rows; a page past the window is rejected with a 400. Reach deeper history with this endpoint's range filters (`block_start`/`block_end`, `timestamp_start`/`timestamp_end`) rather than a larger `page`.

Responses

`200` — Paginated list of blocks matching the filter set

Field	Type	Required	Description
`data`	`array`	Yes
`data[].block_number`	`integer (int32)`	Yes	Block height.
`data[].calls_count`	`integer (int32)`	Yes	Total calls in the block (including children of `batch`/`proxy`/etc.).
`data[].events_count`	`integer (int32)`	Yes	Total events emitted in the block.
`data[].extrinsics_count`	`integer (int32)`	Yes	Total extrinsics in the block.
`data[].extrinsics_root`	`string`	Yes	Extrinsics trie root hash (0x-prefixed hex).
`data[].hash`	`string`	Yes	Block hash (0x-prefixed hex).
`data[].impl_name`	`string`	Yes	Implementation name reported by the runtime.
`data[].impl_version`	`integer (int32)`	Yes	Implementation version reported by the runtime.
`data[].parent_hash`	`string`	Yes	Parent block hash (0x-prefixed hex).
`data[].spec_name`	`string`	Yes	Runtime spec name (e.g. `node-subtensor`).
`data[].spec_version`	`integer (int32)`	Yes	Runtime spec version active at this block.
`data[].state_root`	`string`	Yes	State trie root hash (0x-prefixed hex).
`data[].timestamp`	`string`	Yes	ISO 8601 timestamp with millisecond precision, e.g. `"2024-05-15T10:30:00.000Z"`.
`data[].validator`	`string, nullable`	Yes	SS58 block author. `null` when the producer didn't decode an author (e.g. very early blocks or a header without `PreRuntime`/`Seal` consensus digests).
`pagination`	`object`	Yes	Pagination metadata appended to collection responses. `next_page` / `prev_page` are explicitly required+nullable in the OpenAPI spec: per `docs/api_standards.md` we emit `null` rather than omitting the field, so the SDK should model them as `Option`/nullable types that are always present in the response. `total_items` is the exact number of matching rows on every route (issue #992). It used to stop at 1,000,000, which reported a million transfers when finney holds 7,513,252 and a million events when the real figure is 981,179,110; the cap was removed on 29 Sep 2026 and nothing may reintroduce one — `crate::pagination::exact_count_sql` is the only count form, and `no_capped_count_reaches_the_api_surface` in `data-debug-scripts` fails the build if a capped one comes back. `total_pages` is still bounded, to `crate::pagination::max_reachable_page(per_page)`, because the `page` parameter is capped to a 1,000,000-row window: deep `OFFSET` paging reads every skipped row (24.7M rows / 36.6 GiB / 42 s measured on one endpoint, issue #413). So `total_pages` is exactly the last page this API will serve and `next_page` / `prev_page` stay coherent at the window edge, while `total_items` tells the caller how many rows there really are. History beyond the window is reached with each endpoint's range filters, not a larger `page`.
`pagination.current_page`	`integer (int32)`	Yes	1-indexed page that produced the rows in `data`.
`pagination.next_page`	`integer (int32), nullable`	Yes	Next page number, or `null` if this is the last page.
`pagination.per_page`	`integer (int32)`	Yes	Number of items requested per page.
`pagination.prev_page`	`integer (int32), nullable`	Yes	Previous page number, or `null` if this is the first page.
`pagination.total_items`	`integer (int64)`	Yes	Number of items matching the query across all pages. This is the exact count — every matching row, however many there are. It is not bounded by `total_pages`, so a listing can legitimately report far more items than `total_pages × per_page`.
`pagination.total_pages`	`integer (int32)`	Yes	Number of pages at the current `per_page` that this API will serve: `ceil(total_items / per_page)`, capped at `ceil(1000000 / per_page)` because the `page` parameter only reaches into the first 1,000,000 rows. When the cap bites, `total_items` is still the true total and this is the last page a request can ask for; reach deeper history with the endpoint's range filters instead of a larger `page`.

`400` — Invalid query parameter

Field	Type	Required	Description
`message`	`string`	Yes	Plain-english message describing the failure from the caller's perspective.
`status_code`	`integer (int32)`	Yes	HTTP status code (mirrored in the response status line for convenience).

`500` — Internal server error

Field	Type	Required	Description
`message`	`string`	Yes	Plain-english message describing the failure from the caller's perspective.
`status_code`	`integer (int32)`	Yes	HTTP status code (mirrored in the response status line for convenience).
