Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Polygonscan

  • The PolygonScan API page now redirects to Etherscan's unified multichain API pricing, so Polygon data is bought under Etherscan plans rather than a PolygonScan-specific one
  • The free API plan is capped at 3 calls per second and 100,000 calls per day and requires attribution
  • API Pro endpoints start at the Standard plan at $199 per month
  • Rate limits top out at 30 calls per second even on the $899 per month Pro Plus plan
  • Metadata CSV export and dedicated support require Metadata Enterprise, which is quoted by contact with no published price

Zapper
