cap_class
Market-capitalization tier. One of `nano` (<$50M), `micro` ($50M–$300M), `small` ($300M–$2B), `mid` ($2B–$10B), `large` ($10B–$200B), `mega` (≥$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 columns (which remain in sync as backward-compat shortcuts).

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