Bitquery

Start with the task you need to ship, then pull exactly the on‑chain facts that matter. In the web console, pick a blockchain network (or several), choose the entity you care about—transactions, token transfers, pools, or addresses—and build a query with time windows, token pairs, and method filters. Preview results in seconds, sort by value or gas used, and export to CSV/JSON for spreadsheets or BI tools. Set up alerts to ping Slack or email when a swap crosses a threshold, a wallet interacts with a new contract, or liquidity shifts in a pool you track. For trade analysis, slice swaps by side, route, and price impact, then drill into individual hops to see exact amounts in and out.

If you’re shipping a product, wire the APIs directly into your app. Use REST or GraphQL endpoints to fetch normalized data across chains without juggling node providers. Tie a user’s watchlist to wallet activity, render candlestick charts from aggregated trades, and populate portfolio pages with balances and P&L. Handle pagination for long histories, add caching for hot endpoints, and use webhooks to stream live events like pending swaps or approvals. For reliability, check response schemas, enforce idempotency on retries, and lean on block height cursors to ensure you never miss or double‑count events. Move from staging to production by rotating API keys and applying per‑environment rate limits. more
