Tickers (rows)

A ticker is one tradeable instrument: an equity (AAPL), an interest rate (R:SOFR), a currency pair (X:EURUSD) or a cryptocurrency (X:BTCUSD). The universe is 23,212+ tickers across 4 asset classes.

The non-equity series are curated, not exhaustive. We carry the full US Treasury par-yield curve and the Fed policy rates rather than every rate published; the major currency pairs and spot metals rather than every cross.

Each ticker is one row of the table, carrying every column that applies to its class. The catalog itself is GET /v2/tickers (Tickers › Catalog). The universe tracks the market: new listings appear as they start trading, and a symbol always resolves to whoever holds it now — for delisted companies and reused symbols, read the row as-of a past date and the symbol resolves to whoever held it then.

X: appears twice on purpose. FX and crypto both quote one thing in terms of another, and both live under it — so the prefix tells you a symbol isn’t an equity, but it does not tell you which class it is. Don’t branch on the prefix alone.

The API doesn’t guess. Passing BTC to a stock endpoint returns the Grayscale Bitcoin Mini Trust ETF — a real US-listed equity with that ticker — not bitcoin spot. If you want the cryptocurrency, ask for X:BTCUSD.

• BTC: Grayscale Bitcoin Mini Trust ETF (equity) vs X:BTCUSD (bitcoin spot).
• ETH: Grayscale Ethereum Staking Mini ETF (equity) vs X:ETHUSD (ether spot).

Every class goes through the same endpoints. What changes is which columns are populated. The column set was built for equities, and most of it is meaningless elsewhere — a Treasury yield has no P/E ratio and no earnings date.

• stocks carries the full schema: price, volume, price action, technicals, fundamentals, events, profile, analyst ratings and news.
• rates, fx and crypto carry price, price action and the technical indicators — crypto with volume too — and nothing built on company financials. Equity-specific columns are null on these rows — not false or 0. That distinction matters: a null never satisfies a filter, so a non-equity row cannot accidentally match an equity screen.
• Corporate-event and news endpoints (/v2/events, /v2/news) are stocks-only by definition — a rate pays no dividend. Passing a non-equity symbol returns an error naming its asset class rather than an empty result.

Intraday coverage (1h, 1m) varies by class and is expanding — the major crypto pairs have it, most non-equity series do not yet. Rather than guess from this page, ask: a request for an uncovered interval returns an explicit coverage marker, never a silent empty list, and /v2/tickers/{ticker}/coverage reports exactly what is held per ticker.
