- correctedChoosing a Broker API 2026: Rate Limits, Fees, Auth
Corrected the Tradier trading rate limit in the comparison table: the trade scope is capped at 60 requests/minute in production, not 120 (120/min applies only to the standard and market-data scopes, per Tradier's official rate-limiting docs). Also replaced the IBKR 'per-gateway throttle' cell with the verified 50 messages/second TWS pacing figure.
- correctedReading Financial Filings With LLMs: 2026 Playbook
Removed an unsupported '20 to 40 points' figure and its misattributed footnote (Izacard & Grave 2021, an open-domain QA paper with no SEC filings or hybrid-table experiments). Replaced it with the qualitative claim and an honest TAT-QA citation. Also refreshed stale model pricing (Opus 4.1 to Opus 4.7, GPT-5 to GPT-5.5) and added a sourced long-context financial QA benchmarks section.
- correctedMarket Data APIs Compared: Databento vs Polygon 2026
Corrected the Alpha Vantage row: Premium 600 is $199.99/mo, not $250 ($249.99 is the Premium 1200 tier). Clarified the Polygon.io options and futures cells: each ships as a separate product (Options Advanced and Futures Advanced), both priced at $199/mo — the same as Stocks Advanced, not a higher tier. Updated vendor sources to massive.com (polygon.io now redirects there).
