#Quirks
- Native ETH is not indexed. A large ETH transfer on Base leaves no row. Wrapped ETH as WETH does.
- Two USD Coin contracts.
USDCis the native Circle token.USDbCis the older bridged token. Both are priced asusd-coin. Filter withtoken_addressif you need one, or usetoken in ["USDC", "USDbC"]for both. - **cbBTC is priced as
wrapped-bitcoin.** There is no separate cbBTC price feed in this service. - Shared WETH address.
0x4200000000000000000000000000000000000006is also the WETH address on OP Mainnet. Always pair an address with a chain. - Row volume. Base produced more rows than any other chain in early data. On 2026-11-04 UTC, the stats endpoint showed 2,012 Base rows against 689 Ethereum rows over about 27 minutes. Many are hops of one route, so read transfers vs trades before you sum them.
#Try it
curl -s "https://farbeamlabs.com/api/v1/chains/base"const res = await fetch("https://farbeamlabs.com/api/v1/chains/base");
const { data } = await res.json();
console.log(data.status.status, data.status.head, data.tokens.length);import requests
data = requests.get("https://farbeamlabs.com/api/v1/chains/base", timeout=30).json()["data"]
print(data["status"]["status"], data["status"]["head"], len(data["tokens"]))A rule for this chain, from the Beamline examples style: chain == "base" and token == "cbBTC" and usd >= 500k.
