True crawler cost
DOM churn, IP blocks, compliance risk, and on-call toil are easy to underestimate; outages hit trading and boards directly.
Comparisons
Scraping vs Market Data API
DIY scraping looks cheap until compliance, anti-bot and ops costs add up.
API upside
Stable fields, auth, rate limits, and a status page—engineers build product instead of HTML parsers.
When crawlers remain
Only for non-critical, degradable extras; core quotes/klines should use a formal API with failure monitoring.
Migration tips
Replace poll crawlers with TIQEX REST first, then WebSocket; keep short cache and circuit breakers during cutover.
Entry points
Auth /docs/auth, streaming /guides/websocket-live-quotes, status /status.
