How this service works
Returns price, liquidity, confidence score, main pool, and risk flags for a Base ERC-20 token using Base mainnet DEX liquidity.
Output
Returns a JSON object with the token's USD price (price_usd), 5-minute TWAP (twap_5m), price range (price_low/price_high), total liquidity in USD, a confidence score (0–1), the main DEX pool details (exchange name, pool address, fee tier, pool price and liquidity), a human-readable label, symbol, risk flag array, and a status field indicating ok, not_found, no_liquidity, rpc_error, or unpriceable. Also includes the timestamp of the last update.
Example use cases
Example prompt
“What's the current DEX price, liquidity, and confidence score for the Base token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base mainnet?”
Technical details
Endpoint
GEThttps://fathom-api.mioku-fathom.workers.dev/v1/priceWhen to prefer
Use this endpoint when you need on-chain DEX-derived pricing for a specific Base mainnet ERC-20 token, including liquidity depth, confidence scoring, and risk flags — particularly when you need more than just a price quote and want pool-level detail. Prefer this over centralized price feeds when you need trustless, DEX-native data for Base chain tokens specifically.
Side effects
- Token address not found on Base: status='not_found' with error code and message
- Token exists but has no DEX liquidity: status='no_liquidity'
- RPC connectivity issue with Base node: status='rpc_error'
- Token cannot be priced due to extreme conditions: status='unpriceable'
- Invalid token address format (not a 0x-prefixed 40-char hex): likely 4xx validation error
- Payment not included or insufficient: 402 Payment Required
