Check up to 10 wallets in one call -- mix chains freely (e.g. an Ethereum wallet and a Solana wallet in the same request). Cheaper per item than calling wallet-balance that many times separately. A bad address in the batch doesn't fail the whole call -- that item just comes back with an error, the rest still succeed.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X POST 'https://chainsscope.duckdns.org/tools/wallet-balance/batch' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch -X POST 'https://chainsscope.duckdns.org/tools/wallet-balance/batch'
