Global API Limits

  • 10 apps per account.
  • 10 request-per-second (rps).
  • 90-second request/query timeout.

  • 10 row result limit.

Apache Flight Endpoint

  • API Key (provided as gRPC password) is always required.

SQL Query Limits

Data Limitations (as of June 2022)

  • 128-bit integer limit (while data can be uint256). We include both the 128-bit DECIMAL(38) type and _hex fields where the type is 256-bit.

Data format limitations

  • List data cannot be downloaded as CSV
    • If you wish to download list data as CSV, you should use the flatten operator first:
      • select topics from eth.logs limit 1 will NOT be able to be downloaded as CSV
      • select flatten(topics) from eth.logs limit 1 will be able to be downloaded as CSV
