Query any chain with one parameter

The chain ID on each card is the value the API takes. Every request goes to api.zerion.io, authenticated with your API key.

Scope any call to chains

Pass chain IDs from this page to filter[chain_ids]. Leave it out to get every chain.

GET /v1/wallets/{address}/positions/
    ?filter[chain_ids]=base,arbitrum

Query a testnet

Testnets run in a separate environment. Add one header, keep everything else.

GET /v1/wallets/{address}/positions/
    ?filter[chain_ids]=base-sepolia-test
X-Env: testnet

Fetch the list at runtime

The chains endpoint returns IDs, names, icons and explorers. Don't hard-code the list.

GET /v1/chains/
