Native ETH balance for up to 20 wallet addresses in one call, from Etherscan's V2 API -- a portfolio-style batch lookup instead of N separate /wallet-balance calls. Not address-scoped in the path; pass addresses as a comma-separated query param. $0.01/call.

Read-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optimism with built-in multi-endpoint failover - one paid call, no node or API key of your own. Prefer the named reads (block-number, chain-info, block-info, event-logs, erc721-owner, contract-code) for common tasks - they validate inputs and cost less; use this when you need a whitelisted method they do not wrap.

Top Crypto/NFT News — HIGH-SIGNAL only: hacks/exploits, launches & mainnets, NFT drops/mints, regulation/ETF/legislation, the majors, funding/partnerships; price-prediction/TA chatter and shilling filtered out. Newest first, `since` to poll, `limit` to page; no search.
