How this service works
Returns multi-timeframe Base token price history (1h, 24h, 7d, 30d OHLCV summary), Chainlink vs. Uniswap V3/Aerodrome bid-ask spread in bps, and realized volatility skew.
Output
Returns a structured JSON response containing OHLCV candle summaries across 1h, 24h, 7d, and 30d windows, the bid-ask spread in basis points between Chainlink oracle and Uniswap V3/Aerodrome DEX prices, and a realized volatility skew metric for the requested Base token/quote pair.
Example use cases
DEX oracle spread monitoring for trading bot
“What's the current Chainlink vs Uniswap V3 bid-ask spread in basis points for WETH quoted in USDC on Base — I need to know if there's an exploitable gap before my trading bot executes a swap.”
30-day volatility analysis for DeFi risk model
“Give me the 30-day OHLCV summary and realized volatility skew for the token at Base contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 quoted in USDC — I'm building a risk model for a DeFi lending protocol.”
Token price history review before yield farming
“Before I deploy capital into a Base yield pool, can you pull the 1h, 24h, and 7d price history for AERO quoted in USDC and show me how volatile it's been?”
Technical details
Endpoint
GEThttps://canaryguard-402.onrender.com/v1/tokens/history-and-spread?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cross-source price intelligence on Base — specifically when you want both historical OHLCV context and a real-time oracle vs. DEX spread comparison in a single call. It is ideal for DeFi agents performing pre-trade risk checks, volatility analysis, or arbitrage detection on Base tokens without needing to query Chainlink, Uniswap V3, and Aerodrome separately.
Side effects
- Unknown token symbol or invalid Base contract address returns an error or empty data
- Unsupported window parameter may default to 24h or return a validation error
- Token with insufficient liquidity may return null or zero spread values
- Network or RPC latency on Base may cause timeout or stale data
- Payment failure via x402 protocol results in 402 response and no data returned
