Pred User API is one of 7 APIs that [Pred](https://apis.io/providers/pred/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include User. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and authentication docs.

Safe approval endpoints for enabling trading on your proxy wallet. ## Safe approval signature — raw secp256k1 - Sign the `transactionHash` from prepare response **directly** (raw secp256k1) - **No EIP-191 prefix** / no `personal_sign` - Format: `0x<r><s><v>` (132 hex chars) with low-s normalization - `v` normalized to 27 or 28 **MANDATORY: After completing Safe approval (prepare, sign, execute), you MUST call `POST /api/v1/auth/login-with-signature` again to get a fresh JWT with `is_enabled_trading=true`. Without this re-login, order placement/cancellation will fail with "trading not enabled". A token refresh alone is NOT sufficient.**
