How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns a list of recent whale alert events including large on-chain transactions, the wallets involved, token amounts, chains, and AI-generated intelligence signals about notable DeFi movements. Each alert surfaces data points useful for trading decisions or market monitoring.
Example use cases
Pre-trade market sentiment check
“Before I ape into this position, can you check SperaxOS for any big whale moves happening on-chain right now? I want to know if smart money is buying or dumping.”
Automated DeFi trading signal feed
“Every 15 minutes, grab the latest whale alerts from SperaxOS and flag anything over $500k so I can react to large market-moving transactions in time.”
Research report on whale activity
“I'm writing a DeFi market brief — can you fetch the current whale alert data from SperaxOS and summarize which tokens and wallets are seeing the biggest unusual movements today?”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/intel/whale-alerts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time or near-real-time intelligence on large on-chain wallet movements and whale transactions in DeFi markets, especially if you want to avoid API key management and pay micro-amounts per call in USDC. Prefer it over general blockchain explorers when you need AI-curated, signal-grade whale alerts rather than raw transaction data.
Side effects
- 402 Payment Required if no valid x402 USDC payment is attached
- Stale or empty data if no whale activity meets threshold in recent window
- Malformed filter properties result in ignored params or 400 error
- Network timeout if Base payment settlement is delayed
- Rate limiting if many requests are sent in rapid succession without payment
