Prop firms create accounts without a trader attached and hand the key to their customer (order email, member area). Entering the key here — the app exposes it under **Trading Accounts → Import** — links the account atomically. A key can only ever be redeemed once; the firm is notified via an `account.imported` webhook with your email and the redemption timestamp. **Soulbound identities:** every account carries the firm's customer ID (`customerId`), and each firm customer is pinned to one Hyperprop login. If this customer is already bound to a DIFFERENT Hyperprop login (from an earlier import or a directly-linked account), redemption is refused with `409 TRADER_ALREADY_BOUND` and a masked hint of the correct login. Sign in with that login, or ask the firm's support to rebind your profile to your new login (note: rebinding fails all still-active accounts on the old login). **Check before redeeming:** clients should call `GET /trading-accounts/import/preview` first — it returns what the key unlocks plus a `keyStatus` that surfaces soulbound conflicts (with the masked email) BEFORE the redeem. Both Hyperprop surfaces do this: the manual Import Key dialog (Trading Accounts → Import) and the auto-connect page (`/connect?key=...`). **Error codes:** `INVALID_IMPORT_KEY` (404 — no such key), `IMPORT_KEY_USED` (409 — already redeemed), `TRADER_ALREADY_BOUND` (409 — firm profile bound to another Hyperprop login). ## OpenAPI ````yaml /api-reference/openapi.json post /v1/user/trading-accounts/import openapi: 3.0.0 info: title: Hyperprop Platform API version: 1.0.0 description: >- REST API for the Hyperprop Trading Platform — provision evaluation and funded trading accounts, manage traders and plans, react to account lifecycle events via signed webhooks, and reconcile billing. Built for prop firms integrating from their own backend. ## Authentication Two methods, depending on who is calling: ### Bearer Token (JWT) — users & dashboard Most endpoints accept a JWT via `Authorization: Bearer `. Used by the dashboard and client applications. ### API Key — organizations (prop firms) Organization endpoints also accept `X-API-Key: hp_live_...` for programmatic access from your backend — no browser session needed. Keys are managed by organization admins in the dashboard; each key carries permissions (`read`, `write`, `admin`) and can be rotated or revoked at any time. Keys are stored hashed (SHA-256) — the raw key is shown once at creation. Endpoints that create or modify data require `write` or `admin`. ## Quick Start ```bash # 1. List your trading plans (grab a tradingPlanId) curl "https://api.hyperprop.com/platform/v1/organization/trading-plans" \ -H "X-API-Key: hp_live_your_key_here" # 2. Create a trading account for a trader (by Hyperprop user ID or email) curl -X POST "https://api.hyperprop.com/platform/v1/organization/trading-accounts" \ -H "X-API-Key: hp_live_your_key_here" \ -H "Content-Type: application/json" \ -d '{"type": "evaluation", "tradingPlanId": "", "email": "trader@example.com"}' ``` ## Response Envelope & Error Handling **Success** responses always wrap the payload: ```json { "success": true, "data": { ... }, "message": "optional human-readable note" } ``` **Errors** — including request-validation failures, auth failures, and errors proxied from the trade engine — always return this single uniform shape with a machine-readable `code` you can switch on: ```json { "success": false, "statusCode": 404, "error": "Not Found", "message": "No Hyperprop user found with that email. The trader must have a Hyperprop account before an account can be created for them.", "code": "TRADER_NOT_FOUND" } ``` Parse rule of thumb: check `success`; on `false`, switch on `code` (never on `message` text — messages can be reworded). Some errors carry additional structured context alongside these fields (e.g. payout rejections include a `consistency` block). Common codes: `VALIDATION_ERROR` (malformed payload/params), `UNAUTHORIZED`, `INSUFFICIENT_PERMISSIONS` / `NOT_ADMIN` (key lacks write/admin), `*_NOT_FOUND` (missing resource), `*_NOT_IN_ORG` (resource belongs to another organization), `IDEMPOTENCY_KEY_IN_PROGRESS` (duplicate in flight), `ENGINE_UNREACHABLE` (trade engine down — retry with the same idempotency key). Endpoint-specific codes (e.g. payout `OPEN_EXPOSURE`, `CONSISTENCY_BLOCKED`) are documented on each endpoint. ## Idempotency **Every mutating endpoint (POST, PUT, PATCH, DELETE) honors idempotency keys uniformly.** Send an `Idempotency-Key` header (the `X-Idempotency-Key` spelling is accepted as an alias) to retry any write safely without creating duplicates. How it works: - The key is scoped to your organization + the request path. The first request with a given key executes normally and its response is cached for **24 hours**. - A replay (same key, same path) within 24 hours returns the cached response with an `Idempotency-Replayed: true` response header — the operation is **not** executed again. - If a request with the same key is still in flight, the duplicate gets `409 IDEMPOTENCY_KEY_IN_PROGRESS` — back off and retry; you'll then receive the cached response. - 5xx responses are **not** cached, so retrying after a server error re-executes the request (that's what you want). 2xx-4xx responses are cached — if a request failed validation and you fix the payload, use a **fresh key**. - Keys are free-form strings up to 255 characters. Use something that identifies the operation on your side, e.g. `order-8814-attempt-1`. ```bash curl -X POST "https://api.hyperprop.com/platform/v1/organization/trading-accounts" \ -H "X-API-Key: hp_live_your_key_here" \ -H "Idempotency-Key: order-8814-attempt-1" \ -H "Content-Type: application/json" \ -d '{"type": "evaluation", "tradingPlanId": "...", "traderId": "..."}' ``` This applies to account creation, account PATCH (status, currentBalance, metadata), rules, plans, lockouts, payouts, team, webhooks — every write on the platform API. Payouts additionally forward the key to the trade engine for engine-level double-withdrawal protection. ## Pagination & Sorting List endpoints support both styles: - **Cursor (recommended):** pass `?cursor=` from the previous response's `pagination.nextCursor`. Stable under concurrent writes. - **Offset:** `?limit=&offset=` with `pagination.total` / `hasMore` in the response. Sorting uses `?sort=field:direction` (e.g. `?sort=created_at:asc`); allowed fields are listed per endpoint. Default: `created_at:desc`. ## Custom Metadata Trading accounts, purchases, traders, plans, and rules all carry a free-form `metadata` JSON object. Use it to store your own references — payment IDs, campaign tags, payout records, internal notes. Hyperprop stores and returns it verbatim (and lets you filter list endpoints by it, e.g. `?metadata=stripePaymentId:pi_123`) but never interprets it. Update endpoints support `mergeMetadata: true` for shallow (top-level) merges instead of wholesale replacement. ## Webhooks Subscribe to account lifecycle events (`account.created`, `account.status_changed`, `account.updated`, `account.passed`, `account.failed`, and more) via the Webhooks endpoints. Deliveries are HMAC-SHA256 signed — verify `X-Hyperprop-Signature` with your endpoint secret, using `X-Hyperprop-Timestamp` for replay protection; `X-Hyperprop-Delivery` gives you a unique delivery ID for deduplication. Failed deliveries are retried with backoff, and you can redeliver any event from the dashboard or API. ## MCP Connector (AI Agents) The platform ships a built-in [MCP](https://modelcontextprotocol.io) server, so AI agents and assistants (Claude, Cursor, custom agents) can operate your organization directly — no integration code required. ```http Endpoint: POST https://api.hyperprop.com/platform/v1/mcp Transport: Streamable HTTP (stateless, JSON responses) Auth: X-API-Key header, Authorization: Bearer hp_live_..., or OAuth ``` **Claude web / desktop (Add custom connector):** paste the endpoint URL and leave the OAuth Client ID/Secret fields empty — the connector registers itself automatically. Claude opens a Hyperprop consent page where an org admin pastes the organization API key once; access then follows that key's permissions and ends if the key is revoked. (Under the hood: OAuth 2.1 with PKCE and dynamic client registration.) **Cursor / Claude Code — `mcp.json`:** ```json { "mcpServers": { "hyperprop": { "url": "https://api.hyperprop.com/platform/v1/mcp", "headers": { "X-API-Key": "hp_live_your_key_here" } } } } ``` **Available tools (12):** `list_trading_plans`, `list_trading_accounts`, `get_trading_account`, `get_account_audit_log`, `list_traders`, `get_trader`, `list_purchases`, `get_purchase`, `get_billing_summary` (read) · `create_trading_account`, `update_trading_account`, `record_payout` (write). Every tool call executes the corresponding REST endpoint with your key, so organization scoping, permissions, validation, audit logging, and webhooks apply exactly as documented on each endpoint. Read tools work with any key; write tools need `write`/`admin` permission — connect a **read-only key** if you want a strictly read-only agent. `create_trading_account` accepts an optional `idempotencyKey` so agent retries can't create duplicates, and `record_payout` implements the documented payout recipe (append to `metadata.payouts`, adjust `currentBalance`, audit-logged `reason`). ## Endpoint Groups - **Authentication** — Sign up, sign in, OAuth, MFA, password reset. No auth required for most. - **User** — Profile, notifications, demo accounts, audit logs. Requires **Bearer token** (JWT). - **Organization** — Trading accounts, plans, rules, traders, purchases, lockouts, billing, bulk operations, webhooks, analytics. Accepts **Bearer token** OR **API Key**. - **System** — Health checks.
