BaseBuilder Defi API hub - 22 paid endpoints
Output
Returns a list of DEX trading pairs associated with the queried token, typically including pair contract addresses, token symbols, token addresses for both sides of the pair, and potentially reserve/liquidity data for each pool.
Example use cases
Discover liquidity pools for new token
“I just launched a new ERC-20 token at address 0x1234abcd... on Base — can you find all the DEX trading pairs that exist for it so I can see where it's being traded?”
Arbitrage opportunity research
“I want to find all trading pairs for WETH on Base network DEXes so I can compare prices across pools and spot arbitrage opportunities.”
Portfolio token pair analysis
“Can you pull all the liquidity pool pairs that include the USDC token on Base chain DEXes so I can evaluate which pools have the deepest liquidity?”

Endpoint
POSThttps://bbx-defi.vercel.app/api/dex/token-pairs?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which DEX liquidity pools or trading pairs contain a specific token on the Base network or supported EVM chains. Prefer this over general blockchain explorers when you specifically need structured pair/pool data ready for DeFi analysis, arbitrage research, or liquidity assessment.

- Invalid token address format — returns validation error
- Unsupported chain or DEX — returns error indicating unsupported network
- Rate limiting or payment failure — returns 402 or 429 status
- DEX data source temporarily unavailable — returns 503 or timeout
