answers 402

Top holders of any token on any Blockscout-hosted chain - address, balance, and share of supply, ranked - bought per call from Blockscout's Pro API over x402, no API key. Concentration analysis for any ERC-20/721 on dozens of chains. Mega-tokens with hundreds of thousands to millions of holders (USDC, WETH, AERO) can exceed the upstream time budget - that returns a 500 and you are not charged. Mar
