How this service works
The machine-native marketplace. Wallet = identity. Pay per call with HTTP 402.

Example use cases
Example prompt

Technical details
Endpoint
POSThttps://true402.dev/api/v1/base/whale-swapsWhen to prefer
Use this endpoint when you need real-time or recent on-chain large-trade data from Uniswap v3 or Aerodrome, especially for whale-tracking, market sentiment, or DeFi arbitrage signal use cases. Prefer this over CEX trade feeds when you specifically need DEX on-chain swap data with block-level granularity.
Side effects
- Invalid DEX value (not 'uniswap-v3' or 'aerodrome') returns error
- Limit outside 1–200 range may return validation error
- Invalid or future block number in 'since' returns empty or error
- Payment failure (HTTP 402) if wallet has insufficient USDC balance
- Network or indexer downtime returns 5xx error
