How this service works
Returns tamper-resistant on-chain USD spot prices, 24h volatility, and Chainlink/TWAP oracle deviation metrics for major Base and EVM assets.
Output
Returns tamper-resistant on-chain USD spot price for the requested asset, its 24-hour volatility figure, and deviation metrics comparing the Chainlink oracle price against the TWAP (time-weighted average price), helping agents detect price manipulation or oracle staleness before executing on-chain transactions.
Example use cases
Pre-trade oracle sanity check
“Before I execute this WBTC swap on Base, can you pull the on-chain USD spot price and check whether the Chainlink oracle is significantly deviating from the TWAP? I want to make sure there's no price manipulation risk.”
DeFi yield strategy price validation
“I'm about to deposit into a Morpho USDC pool on Base — can you fetch the on-chain spot price and volatility for USDC and flag if there's any oracle deviation I should be worried about?”
Real-time crypto volatility monitoring
“What's the 24-hour volatility and Chainlink deviation for ETH on Base right now? I'm trying to decide whether market conditions are too choppy to rebalance my portfolio.”
Technical details
Endpoint
GEThttps://canaryguard-402.onrender.com/v1/crypto-price-onchain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need tamper-resistant, on-chain validated price data with oracle deviation analysis — specifically Chainlink vs TWAP comparison — for Base and EVM assets, rather than relying on off-chain CEX price feeds. Ideal before executing DeFi trades, validating collateral values, or auditing smart contract price dependencies where manipulation resistance matters.
Side effects
- Unknown or unsupported asset symbol returns an error or empty result
- Network congestion on Base may cause stale on-chain data
- Symbol ambiguity (e.g. multiple tokens with same ticker) may return unexpected asset data
- Oracle data unavailable for low-liquidity or newly listed tokens
- Payment failure (insufficient USDC balance) blocks the request under x402 protocol
