Example use cases
Backtesting crypto strategy with candles
“Pull the last 500 daily OHLCV candles for ETH so I can run a walk-forward backtest on my momentum strategy.”
Real-time short-term signal generation
“Get the most recent 50 one-minute OHLCV bars for SOL — I want to feed them into my regime detection model right now.”
Volume profile analysis for session levels
“Fetch 200 four-hour candles for BTC so I can compute session volume area levels and identify key support and resistance zones.”

Endpoint
GEThttps://x402.wintergreen.uk/api/v1/quant/ohlcvWhen to prefer
Choose this endpoint when you need raw OHLCV candlestick data for crypto assets and are operating within an x402-capable agent that can handle micropayments in USDC on Base. It is well-suited for quant workflows, backtesting pipelines, and signal generation where per-call costs of $0.001 are acceptable. Prefer it over free public endpoints when you need data integrated into a paid Wintergreen intelligence workflow or when other Wintergreen quant signals (funding, liquidation, regime) are also being consumed.
Side effects
- HTTP 402 returned if payment header is missing or invalid — agent must sign EIP-712 TransferWithAuthorization and retry with X-PAYMENT header
- Invalid symbol returns error or empty dataset
- Unsupported interval value may return error
- Limit parameter out of range may cause error or truncation
- Network timeout if Wintergreen endpoint is unavailable
