What you get today

A free key
Near real-time quotes, full daily history and every endpoint on the free tier. A card on file is required before your first key — you're only charged if you upgrade.
YH-compatible shapes
quoteResponse, chart, optionChain — existing parsers, SDKs and spreadsheets keep working.
Rate-limit headers
Every response reports where you stand; your dashboard shows the same counters live.
Upgrade in place
The same key gets the bigger allowance minutes after you subscribe. Nothing to re-issue, nothing to redeploy.

Quotes and charts refresh from the source at request time — in market hours a quote is at most about a minute old — with full warehouse history behind them for research, dashboards and backtests.
