Technical details
Endpoint
POSThttps://true402.dev/api/v1/base/new-pairsWhen to prefer
Use this endpoint when you need real-time discovery of newly created trading pairs or token launches on Base chain DEXes, specifically Uniswap v3 or Aerodrome. Prefer it over generic blockchain explorers when you want structured, filtered pair data without parsing raw chain events.
Side effects
- Invalid DEX name (not 'uniswap-v3' or 'aerodrome') returns an error
- Limit out of range (outside 1–200) returns a validation error
- Payment failure via HTTP 402 if USDC wallet balance is insufficient
- No pairs found matching the since-block filter returns empty list
- Network or RPC timeout for on-chain data queries
