Historical data

Backfill the full history of any chain

Replay an entire chain into your own database, from genesis to the current block, without running an archive node and without rebuilding your indexer.

See the page ⟶ Decoded data

Decoded transactions, not raw blocks

Get swaps, transfers, balances and positions as entities your product already understands, instead of logs you have to interpret yourself.

See the page ⟶ Chain data in SQL

Chain data in SQL, without the pipeline

Land blockchain data in Postgres or ClickHouse with the writes, the checkpoints and the reorganization handling already taken care of.

See the page ⟶ Real-time streams

The head of the chain, pushed to you

A continuous stream rather than a polling loop, with a cursor you can resume from and reorganizations handled explicitly.

See the page ⟶ Access by chain

Query a chain from genesis

Historical and live data for the chain you work on, in one stream, without running a node or maintaining an indexer.

See the page ⟶ Agent access

Blockchain data your agent can read

A machine-readable surface for coding agents and assistants: a published specification, installable skills, and access that does not require a human to open a dashboard.
