* Token balances on one or more blockchains * Current USD price, BTC price, and 24h change * Token contract addresses and decimals (ERC20-style tokens) * Market data: rank, 24h volume * address: Wallet address to query * One of connectionId or blockchain (if both provided, connectionId is used): * Single value (e.g., "ethereum") * Comma-separated values ("ethereum,polygon") * "all" — every supported network (top-tier EVM chains forced; other chains bounded by a per-chain latency limit and may be skipped) * "forceall" — every supported network, no latency limit (the response is delayed by the slowest chain) * The top-tier EVM chains forced under "all" are: ethereum, binacesmartchain, base-wallet, polygon-wallet, arbitrum-wallet, optimism-wallet, avalanche-wallet, hyperevm-wallet, monad-wallet, plasma-wallet. In rare cases a slow non-top-tier chain may be omitted; use "forceall" to wait for everything. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/wallet/balance openapi: 3.0.0 info: title: CoinStats Public API description: >- CoinStats Public API — programmatic access to market data, news, NFTs, wallets, exchange connections, and user portfolios.
