rateLimits: - name: No Official API Rate Limits Published description: >- Firstrade does not publish an official public REST API and therefore does not publicly document API rate limits. All programmatic access to Firstrade account data runs through the Plaid financial data aggregation platform, which enforces its own rate limits per developer account tier. Plaid's rate limits vary by product and pricing plan and are documented in Plaid's developer documentation. url: https://plaid.com/docs/api/ - name: Plaid Rate Limits (applicable when accessing Firstrade via Plaid) description: >- When accessing Firstrade data through Plaid, the applicable rate limits are those of the Plaid API. Plaid enforces per-endpoint rate limits that scale with developer plan tier (Launch, Scale, Enterprise). Specific numeric limits (requests per minute or per day) are tier-dependent and detailed in Plaid's official rate-limiting documentation. Developers on the Launch plan face lower thresholds; Scale and Enterprise plans provide higher throughput. Plaid may impose additional throttling on investment data endpoints due to data freshness and reconciliation windows. url: https://plaid.com/docs/errors/rate-limit-exceeded/ notes: >- Firstrade's web and mobile platforms use session-based authentication with no publicly documented rate limits for end-users. Unofficial community SDKs that reverse-engineer the Firstrade web session may encounter undisclosed server-side throttling. Firstrade has not published any documentation on automated access policies. Contact Firstrade support at 1-800-869-8800 for institutional or automated access enquiries.
