How this service works
Blockchain data APIs with x402 payments on Solana + Base via PayAI facilitator. 7 endpoints covering bridge routing, whale alerts, DeFi yields, RPC, NFT, token, and transaction history.
Output
A list of whale transfer alerts for the specified chain, each containing transaction details such as token symbol, transfer amount in USD, sender and receiver wallet addresses, and transaction hash. Results are filtered by the optional minimum USD amount and token symbol, capped at the specified limit.
Example use cases
Pre-trade whale movement check
“Before I make a trade, can you pull the last 10 whale alerts on Ethereum for ETH transfers above $1,000,000 so I can see if big wallets are moving?”
DeFi token monitoring on Base
“I want to keep an eye on big USDC movements on Base — fetch me up to 25 whale alerts for transfers over $250,000.”
Cross-chain large transfer scan
“Can you check for any large token transfers on Arbitrum right now — no token filter, just anything above $100,000, and give me up to 50 results?”

Endpoint
POSThttps://solana-x402-xi.vercel.app/api/v1/whale-alertsWhen to prefer
Choose this endpoint when you need real-time or near-real-time detection of large on-chain token movements on EVM-compatible chains like Ethereum, Base, Polygon, or Arbitrum. It is ideal for trading signal pipelines, DeFi risk monitoring, or alert systems that need to react to whale behavior. Prefer it over generic block explorers when you need pre-filtered, USD-denominated transfer data via a simple API call.
