/api/v1/quote/:symbolFreeReturns a last/spot quote for a stock, ETF, or crypto symbol. Crypto pairs accept slash or dash form (BTC/USD, BTC-USD). Ambiguous bare names such as PUMP, LIT, and VVV resolve as US equities — use PUMP/USD for the token. Responses echo asset_class and venue. Unknown/unavailable quotes return HTTP 422 with ok:false and price:null (never numeric 0).

}/api/v1/signals/{symbol}ProAI consensus signal with component scores, entry, stop, and targets. Documented path: GET /api/v1/signals/{symbol}. data.price is live last/spot (price_source=live_quote), never a silent prior close. Nightly engine is omitted and engine_available is false when runAt is stale beyond 1440 minutes. BTC/ETH/SOL are in the nightly universe. Ambiguous bare tickers (PUMP, LIT, VVV) resolve as equities — use PUMP/USD for crypto. Responses echo asset_class and venue.
