This is the **default shared quota** — it is shared with every other endpoint that has no dedicated limit, so requests across those endpoints all draw from the same budget. --- A dry run of the register operation that changes nothing: verifies whether the authenticated account can copy the given investor with the given amount. Request body is the same as starting a new copy (POST /api/v2/trading/copy/demo). A positive verdict is a point-in-time check, not a reservation. When isSuccess is false, errorCode and errorMessage may be absent. ## OpenAPI ````yaml /api-reference/openapi.json post /api/v2/trading/copy/demo/eligibility openapi: 3.0.1 info: title: eToro Api version: v1.352.0 description: >- eToro’s public API provides access to real-time financial data, trading insights, and account management features, allowing developers to integrate eToro’s services into their applications. With access to market prices, historical data, and social trading information, the API empowers users to enhance their trading strategies. Designed for security and scalability, the eToro API ensures smooth and reliable integration for a variety of financial applications. For more details on integrating with eToro's public WebSocket service, please refer to the dedicated [WebSocket documentation](./websocket/websocket-doc.html). ## Authentication Every request must be authenticated with exactly one of two options: an OAuth 2.0 access token (`Authorization: Bearer `), or the non-interactive credential pair (`x-api-key` + `x-user-key` headers). The two options are mutually exclusive — a request carrying both is rejected. Each operation lists the OAuth scopes that grant access as alternative security requirements: a bearer token needs only ONE of them, and the same permissions govern the credential pair. servers: - url: https://public-api.etoro.com description: eToro Public API security: - apiKeyAuth: [] userKeyAuth: [] - oauth2: [] tags: - name: Agent Portfolios - name: Social Feeds - name: Balances - name: Clubs - name: Watchlists - name: Top Assets - name: App Data - name: Market Data - name: Identity - name: Cash Accounts - name: Transfer - name: Notifications - name: PI Data - name: PortfolioSearch - name: Price Alerts - name: SSO - Applications - name: SSO - Scopes - name: Sub-Accounts - eToro Trading - name: Sub-Accounts - name: Trading - Demo - name: Trading - Real - name: Users Info - name: Rankings - name: User Stats - name: Copy Trading - name: Copy Trading - Demo paths: /api/v2/trading/copy/demo/eligibility: post: tags: - Copy Trading - Demo summary: Pre-check whether a copy registration would be allowed description: >- **Rate limit:** 60 requests per 60 seconds.
