Requires complete trading and risk evidence, the profit target, minimum fill-based session days, no positions/orders/unresolved commands, no recorded disqualifying loss/evaluation breach, and an active firm_halt. Does not advance a challenge. Poll safely; transitionReference is stable for account cycle + stageId and can be used as the next account creation referenceId. It is not a reservation or permanent pass certificate. Keep the old account halted and serialize stage transitions in your backend. Rules outside evaluatedRules must be checked by your firm. ## OpenAPI ````yaml /partner-platform/openapi.json get /api/partner/accounts/eligibility openapi: 3.1.0 info: title: trdrs Engine API version: 1.1.0 description: >- ## API Reference This is the served OpenAPI contract for the trdrs engine: market data, trading and account routes for your firm's traders, trdrs Connect account-registration handoff, and preview challenge routes. See Quick Start for the first integration path: key setup, market config, chart data, Connect account registrations, idempotency, stream reconnects, and conformance. See Overview and API Standards for the cross-cutting contract rules. servers: - url: https://app.trdrs.co description: Production - url: / description: This engine security: [] tags: - name: Market data description: >- Symbol search and resolution, OHLCV history, quote snapshots, the server clock, and the live bar stream. Crypto rides each venue’s public feed; futures stream from the caller’s own connected Rithmic account. With none connected, futures requests answer 503 `feed_requires_connection`. - name: News description: >- Aggregated market news and the economic calendar, from licensed/open sources, keyword-tagged with futures roots at ingest. Platform-wide content (nothing per-user), admitted exactly like Market data: a licensed origin, a session, or a firm API key. Headlines page by published time, scope by instrument root, and stream live over SSE; thumbnails serve through the image proxy. - name: Trading description: >- The money surface: entries, exits, replaces, cancels, and position/account flattening. Every order-placing call uses `clientOrderId` as its idempotency key. - name: Account description: >- Reading a connected account. You do not create trading accounts here: a trader connects their own broker account (or creates a free demo account) in the app, and firms create evaluation accounts through the Partner API (Firm accounts → Create evaluation accounts) or register venue accounts through Connect (Create an account registration). Account state and the durable ledgers: balances, positions, working orders, fills, P&L history, and the live account stream. - name: Connect description: >- trdrs Connect account registration, for partner firms. Register an account you issued on your own venue — a pending account registration — with the trader’s sign-in email, optionally the venue account id and the login name your venue issued. The trader finds it waiting in the connect flow the moment they sign in with that email: the connect step is pre-filled with everything except the credential, which the trader always enters themselves. A registration never transmits a password and never grants access to anything before the trader’s own login succeeds. These routes answer a partner-scoped key only; a firm API key or a user session gets 401. Registrations expire after 30 days; re-registering the same email + account refreshes the expiry instead of duplicating. The end-to-end flow guide is **[Quick Start](/docs/guides/quick-start)**. - name: Firm accounts description: >- Evaluation accounts your firm issues on the trdrs venue, through your partner key — the other half of account setup. Connect registrations hand off accounts that exist on your venue; these routes create and manage accounts on ours: the trader trades them on trdrs, and your firm owns the lifecycle. Every route is scoped to accounts your firm created through this API — an account the same trader opened themselves is invisible and untouchable here, by construction. Creation is batched with per-item results, and every write carries your own `referenceId`, so a crashed pipeline retries safely. Served when the deployment runs the prop engine; without it, every route in this group answers `404`. - name: Webhooks description: >- The outbound event bus: register an https endpoint and the platform pushes events to it instead of your back office polling us. Every delivery is signed (`trdrs-signature: t=,v1=` over `${t}.${rawBody}`) so you can prove it came from us and is fresh, and every delivery is durable — a failed attempt is retried with backoff for about nine hours and the whole log is readable, so an endpoint that was down is a delay rather than a lost event. Serves brokers and prop firms alike: the account-registration (`registration.*`) events fire wherever Connect does, and the account events fire where the prop engine runs. - name: Challenges description: >- The prop evaluation surface: challenge programs and a trader’s own enrollments. **Preview: the one group on this page outside the additive-only guarantee** (the pre-contract v1 scaffold; the Phase-1 rebuild will change these shapes; see Stability). **Cookie-authenticated, not key-authenticated**, and served only when the engine runs with `CHALLENGES_ENABLED`; without that flag the bundle is absent and every route below returns `404`. The firm-console/admin half of this surface is deliberately not documented here. It is back office, not licensed surface. paths: /api/partner/accounts/eligibility: get: tags: - Firm accounts summary: Check stage eligibility description: >- Read-only, fail-closed check of the firm-supplied stage rules.
