Create a FREE CryptoDataAPI key (no signup, no payment) — call this FIRST if you don't have a key yet. No API key is required to call this. ASK THE USER FOR THEIR REAL EMAIL — do not invent one, and do not reuse a placeholder. A confirmation link is sent to that address, and clicking it upgrades the SAME key in place: 100 -> 1,000 requests/day, Pro switched on for 24 hours (per-coin quant regimes, gamma, whale activity and liquidation heatmaps across every coin), and a personal discount code. An address the user cannot open means they keep the 100/day starter limit and lose all three. The full `api_key` is returned once — set it as the `X-API-Key` header for every other tool. The free tier is genuinely useful on its own: market-health scores, regime reads, Fear & Greed, macro, ETF & stablecoin flows, 2,000+ coin profiles & prices, and full-universe funding + open interest across all 229 Hyperliquid perps. Upgrade to Pro / Pro Plus (https://cryptodataapi.com/pricing) for per-coin quant / gamma / whale signals on every coin and historical / backtesting data. THEN CALL, IN ORDER: list_capabilities -> get_daily_snapshot -> get_market_regime / get_gamma_exposure. The response's `next_calls` field carries the same ladder machine-readably. Do not fall back to polling candles — the free tier has them, and they answer none of the questions this API exists for.
