Override partial of ADR 0011: Tiingo Power pre-designation is invalidated by 2026 pricing reality (~30 USD/mo, not 10) AND by ToS (Power tier is internal-use only; multi-tenant proxy requires Commercial 500+/mo plus a redistribution license). Alpha Vantage Premium 49.99 USD/mo retained as direct Yahoo replacement, under suspensive condition of written ToS authorization for commercial multi-tenant proxy use. Phase 2 smoke test surfaced a key finding: Alpha Vantage silently accepts Yahoo-style .TO ticker suffix as alias of .TRT, removing the need for any mapping table. Drop-in compatible with existing Yahoo provider code. Refs maximus-api#41 |
