cap_class
Market-capitalization tier. One of `nano` (<$50M), `micro` ($50Mâ$300M), `small` ($300Mâ$2B), `mid` ($2Bâ$10B), `large` ($10Bâ$200B), `mega` (â¥$200B), or `unknown` when `market_cap` is null. Updates daily post-close as `market_cap` moves. Preferred over the legacy `nano_cap/micro_cap/small_cap/mid_cap/large_cap/mega_cap` boolean signals (which remain in sync as backward-compat shortcuts).

}Same grammar on scan and webhooks. This signal is live-tense only — it isn't historized, so ?asof= reads and series pulls don't carry it.
