Requires `Authorization: SIWE ` from a `login` action (or an API key whose Kairos account owns the wallet). **The body is nested:** the rows are at `positions.positions`, with `positions.resolved`, `positions.closed` and `positions.asOf` beside them. When a venue cannot be read, `venueDetail..error` says why. ## OpenAPI ````yaml /openapi/wallet-api.json get /v3/wallets/{address}/positions openapi: 3.1.0 info: title: Kairos Partner API version: 1.0.0 description: >- Self-custody trading for wallets and apps: Kairos builds each step, the user's wallet signs it.
