Builders - Hypedexer Docs

Hypedexer provides builder analytics: rankings, fee breakdowns, per-coin stats, and top users for each builder. Use the REST API section below to query builder data on api.hypedexer.com.

Are my users trading elsewhere?

POST /builders/{builder_address}/external-activity takes a list of wallet addresses and tells you, for each one, whether it has recent fills under another builder code (a competing app) or with no builder code at all (the official Hyperliquid UI, bots, any tool outside the builder program). Flagged wallets come first, sorted by external volume.

curl -s -X POST "https://api.hypedexer.com/builders/0xYOUR_BUILDER/external-activity" \
  -H "X-API-Key: $HYPEDEXER_API_KEY" -H "Content-Type: application/json" \
  -d '{"users": ["0xabc…", "0xdef…"], "timeframe": "7d"}'

Builder attribution on fills is available from 2025-10-10.
