QuickNode supports the following Sei APIs on all endpoints. Using your Sei endpoint, you can call any of the methods available in these APIs. For a complete list of supported RPC methods, refer to the documentation for each API.
Cosmos SDK and CosmWasm functionality will be deprecated in favor of EVM-only. For more details, see SIP-3 and the governance proposal.
Supported APIs
QuickNode's Sei Pacific endpoints provide full archive data access starting from block height 1 (genesis).
For blocks >= 78309999:
Use the x-cosmos-block-height header with REST API requests or specify the height parameter with Tendermint API requests:
Cosmos REST API Example:
curl --location 'https://docs-demo.sei-pacific.quiknode.pro/cosmos/distribution/v1beta1/delegators/sei1xyp8xxely9txewfe7nes2nxrzr0qyrfghrj5cs/rewards' \
--header 'x-cosmos-block-height: 78309999'
Tendermint API Example:
curl --location 'https://docs-demo.sei-pacific.quiknode.pro/block?height=78309999'
For blocks < 78309999:
Use the x-qn-height header for COSMOS SDK APIs and TENDERMINT APIs. If you need to query at a specific historical block, use both x-qn-height and x-cosmos-block-height headers:
Transaction Query Example (block < 78309999):
curl -H 'x-qn-height: 73104809' 'https://docs-demo.sei-pacific.quiknode.pro/cosmos/tx/v1beta1/txs/7E84D96044AB1E382C0CDFAFF85067D1742D69FD8D5010350C87890D9E95C193'
Historical Balance Query Example (specific block < 78309999):
curl 'https://docs-demo.sei-pacific.quiknode.pro/cosmos/bank/v1beta1/balances/sei1vfxlpud2txs7en5z7qgf4qk93e64p7r3qlqjpn' \
-H 'x-qn-height: 73104809' \
-H 'x-cosmos-block-height: 73104809'
For Sei EVM methods:
No special headers are required. The earliest block number for EVM methods is 79123881 (Sei V2 upgrade block).
