How this service works
USD price for major tokens by symbol or any Base ERC-20 by contract address, with source failover.
Output
A USD price value for the requested token, sourced from multiple providers with automatic failover if one source is unavailable. Returns the current market price as a numeric value.
Example use cases
Check BTC price before trading
“Hey, what's Bitcoin going for right now in USD? I want to know before I make a move.”
Look up Base token portfolio value
“I have a few tokens on Base — can you grab the current USD prices for USDC and the ERC-20 at contract address 0x4200000000000000000000000000000000000006 so I can calculate my portfolio value?”
Monitor SOL and ETH prices
“What are SOL and ETH trading at right now in dollars? I need both prices to decide how to rebalance my holdings.”
Technical details
Endpoint
GEThttps://quartermaster.surewhynot.app/v1/priceWhen to prefer
Use this endpoint when you need a quick, reliable USD price for a major crypto token (ETH, BTC, SOL, USDC, etc.) or any ERC-20 token deployed on Base, especially when you need source failover reliability and are already operating within the x402/Bazaar ecosystem. Prefer this over general-purpose price APIs when working with Base-native ERC-20 tokens by contract address.
Side effects
- Unknown token symbol returns an error or null price
- Invalid or non-Base contract address returns an error
- Token with no price feed available returns an error
- All price sources are unavailable triggers failover exhaustion error
- Malformed query parameter returns 400-level error
