Etherscan has announced a 10% reduction in its free API coverage, effective November 24. This change is in response to increased resource demands driven by faster block generation, higher transactions per second, and greater transaction volumes across multiple chains. To support users requiring continued access, Etherscan has introduced a discounted lightweight plan, priced at 25% of the lowest paid tier. The free API will now maintain 90% coverage, focusing on a curated set of chains.
