Key Features

  • Unified datasets — raw, decoded, and abstracted tables across 50+ chains
  • Parameterized queries — use {parameter} placeholders for reusable templates
  • File Explorer — save and organize your queries
  • Generate API — turn any saved query into a REST endpoint with one click

​
Generate an API from Your Query

After saving a query, click Generate API to create a callable endpoint: 
const response = await fetch(
  `https://api.chainbasehq.com/v1/query/${queryId}/execute`,
  { method: "POST", headers: { "API-KEY": apiKey } }
);
