Trader Analytics

Search for a trader's public profile by wallet address

Fetches public profile information (display name, pseudonym, bio, avatar, X/Twitter handle, verification badge, associated user IDs) for a wallet address from the upstream provider. Provider is auto-detected from address format when omitted — Ethereum (0x…) addresses default to Polymarket and Solana addresses default to Kalshi; auto-detection maps every 0x address to Polymarket, so other EVM venues (Opinion, predictfun, …) must pass provider explicitly. provider, when given, is validated against the central provider registry shared with /trader-stats; any registered provider is accepted, and non-Polymarket venues currently receive a synthetic (service-generated) profile rather than a live upstream fetch. This is a live provider read, not served from cached data. Auth: accepts an admin secret (X-Admin-Secret), an API key (X-Client-Id + X-Api-Key + X-Api-Secret), or a first-party JWT (Authorization header or turnkey_session_jwt cookie). No API-key scope is required — any valid credential can read a public profile. Rate-limited by the heavy group at 10 requests/minute, matching /trader-stats, because every call is a live upstream provider read.
