Use it to see which terms your accounts are held to now. Required scope: `venue:read`. Preview: served on the sandbox to every venue, and production availability is arranged when a venue qualifies. Trading API keys and Partner keys do not authorize these routes. ## OpenAPI ````yaml /api/openapi.json get /api/partner/venues/{venueId}/risk-policies openapi: 3.1.0 info: title: trdrs Engine API version: 1.1.0 description: >- ## API Reference Every route the trdrs engine serves, with what to send and what comes back. It covers market data and news, trading and account state for a trader's own software, Connect pre-registration, the venue routes a prop firm or brokerage runs its accounts through, and the Legacy Partner API. Start with the Quickstart for your first call. The API standards hold the rules every route shares: keys, errors, rate limits, idempotency, paging and streaming. servers: - url: https://app.trdrs.co description: Production - url: / description: This engine security: [] tags: - name: Venue platform preview description: >- Run your venue: its providers, instruments, conditions, groups, routes, stages, venue rules, keys, accounts, usage, balance receipts and webhooks. These routes are in preview. They are served on the sandbox to every venue, and production access is arranged when a venue qualifies. Every route here under `/api/partner/` takes a Venue key. The back office reaches the same routes under `/api/operator/` with a verified owner’s session, because a browser never holds a Venue key, and both run the same checks. Changes to these routes are additive only from here on, and the Legacy Partner API routes stay as they are. - name: Market data description: >- Search and look up symbols, read price history and quotes, check the server clock, and stream live bars. Crypto prices come from each provider’s public feed. Futures prices are licensed to each user and stream from your own login at a provider that carries them, so without one connected, a futures request answers 503 `feed_requires_connection`. - name: News description: >- Market news and the economic calendar, from licensed and open sources, tagged with futures roots as they arrive. The content is the same for everyone, and these routes admit the same callers as market data: a licensed origin, a session or a Trading API key. Page headlines by publish time, filter them by instrument root, and stream them live over server-sent events. Thumbnails come through the image route. - name: Trading description: >- Place, change and cancel orders, set a position’s exits, and close or flatten positions. Every call that places an order takes a `clientOrderId` as its idempotency key. - name: Account description: >- Read an account a trader can trade: its balance, positions, working orders, fills, profit and loss history, and the live account stream. You don’t create accounts here. A trader connects their own account at a provider, or opens their own Demo on the paper book, in the trdrs app. A venue issues accounts on the paper book with Issue an account into a group, and a firm pre-registers accounts at a provider through Connect with Pre-register a trader’s account. - name: Connect description: >- Connect is the account picker a trader opens, in the trdrs app or embedded on a firm’s site. It lists the built-in providers and every listed venue. The pre-registration routes let a firm fill it in ahead of time. You tell trdrs that a trader has an account at a built-in provider: their sign-in email, and optionally the account number and login name. When that trader signs in, Connect shows the account ready to link, and they sign in to the provider themselves, once. Nothing here sends a password or grants access before the trader’s own login succeeds. You can list who you pre-registered and who has linked, and cancel a pre-registration that hasn’t been used. A pre-registration expires after 30 days, and sending it again refreshes it. These routes take the Partner key. They belong to Connect, not to the Legacy Partner API. The whole flow is in the **[Quick Start](/docs/guides/quick-start)**. - name: Firm accounts (legacy) description: >- Legacy Partner API. Each route here has a venue twin under `/api/partner/venues/{venueId}/accounts…`, which takes a Venue key and a named scope, and new integrations use those. This group stays for firms that predate venues, and both run the same operation. These routes issue and manage evaluation accounts on the paper book with your Partner key: the trader trades them on trdrs, and your firm owns their lifecycle. Every route sees only the accounts your firm created through this API, so an account the same trader opened themselves is invisible here. Creation is batched with a result per item, and every write carries your own `referenceId`, so a pipeline that crashes can retry safely. These routes are served where the engine runs prop evaluations. Elsewhere, every route in this group answers `404`. - name: Billing description: >- Legacy Partner API, per firm. What your firm is billed for in a month, counted from its fills, and the accounts behind the number. The venue routes Read the venue’s metered usage for a month and Read the accounts behind the venue’s usage replace these, which still take the Partner key. - name: Webhooks description: >- Legacy Partner API. The venue routes Register a webhook, List the venue’s webhooks and Read a webhook’s delivery log replace these, with a Venue key, and an endpoint registered either way receives the same events. Register an https endpoint, and trdrs pushes events to it, so your back office doesn’t have to poll. Every delivery is signed (`trdrs-signature: t=,v1=` over `${t}.${rawBody}`), so you can prove it came from trdrs and is fresh. Every delivery is also durable: a failed attempt is retried with backoff for about nine hours, and the whole log is readable, so an endpoint that was down gets its events late rather than never. The pre-registration events (`registration.*`) fire wherever Connect runs, and the account events fire where the engine runs prop evaluations. - name: Challenges description: >- Legacy Partner API. Stage policies on a venue replace the firm’s half of this, and the trader’s enrollment flow has not moved yet. These routes list evaluation programs and a trader’s own enrollments. **Preview: the one group in this reference outside the additive-only guarantee.** Their shapes will change when challenges are rebuilt; see Stability. **They take a signed-in session, not a key**, and are served only where the engine runs with `CHALLENGES_ENABLED`. Without it, the routes don’t exist and every one answers `404`. The administration half isn’t documented here, because it is trdrs’s own tooling, not part of the API. paths: /api/partner/venues/{venueId}/risk-policies: get: tags: - Venue platform preview summary: List the venue's risk policies description: >- Lists every risk policy the venue states, with its stored versions, its publications in order, and the version in force, which is the latest one published.
