Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/priceWhen to prefer
Use this endpoint when you need a trustworthy, on-chain-derived USD spot price for a token — especially for tokens in the Base ecosystem or those with Chainlink feeds — rather than relying on a centralized exchange API or off-chain aggregator. Ideal for DeFi agents, portfolio trackers, or any workflow that requires verifiable price data sourced from public blockchain state.
Side effects
- Unsupported or unknown token symbol returns an error or empty result
- Token not listed on Chainlink or any liquid Base DEX pool may have no price available
- Network issues or RPC node latency may delay or fail the on-chain lookup
- Malformed token symbol parameter returns a validation error
