# Blockchain Data API datasets: choose data for your application

> Original page: https://docs.blockvectra.com/en/datasets/

Choose Blockchain Data API datasets by task and check the chain matrix below. For wallet assets, start with [token balances](https://blockvectra.com/en/data/balances/) and [token transfer history](https://blockvectra.com/en/data/transfers/); for tokenized stock activity, see the [stocks guide](https://docs.blockvectra.com/en/guides/stocks/). Once you have chosen a dataset, use the [Data API reference](https://docs.blockvectra.com/en/api/data/) for request parameters and response schemas, or the [Quickstart](https://docs.blockvectra.com/en/quickstart/) for your first call.

## What's available

* **Blocks & transactions** — block and transaction data, including event logs and execution traces (where supported).
* **Token transfers & balances** — ERC-20 transfer history and address balances.
* **Token holders** — holders and balances per token.
* **Tokenized stocks** — US stocks and ETFs issued on supported chains as tokens.
* **DEX trades & daily prices** — decentralized exchange trades and daily prices.
* **NFT holdings** — current holders and balances.
* **Data freshness** — how far each dataset lags behind the indexed chain head.

Partial = only some of this dataset's endpoints are enabled on that chain.

### Coverage notes

* **Ethereum window**: coverage for transfers and address transactions is determined by `coverage.from_block` in `GET /v1/data/chains`; a response that crosses the window start is marked `meta.coverage: "partial"`.
* **Traces**: available on select chains only, from a certain block onward, with a small number of gaps (see [Supported Chains](https://docs.blockvectra.com/en/chains/)).

✗ means requests return `422 no_coverage` (not billed).

See [Supported Chains](https://docs.blockvectra.com/en/chains/) for endpoint URLs, chain IDs, and additional per-chain details.
