GET /api/history/:solana_address
needs-input
Price History (OHLCV). OHLCV price history (day/hour/minute candles) from the highest-liquidity pool for this mint. The only time-series endpoint here — every other route is a point-in-time snapshot.
Verdict: not verified by an unpaid GET. 400/422: wants input before the 402. This says nothing about whether the route works when called as declared.
