Crest Wallet Intelligence (x402) — wallet score, whale & risk profiling
Onchain wallet intelligence and reputation scoring for AI agents. Profile any Base or EVM wallet, or any x402 buyer: whale score, address risk, counterparty check, behavior cluster, spend graph, repeat-rate, and full x402 payment history. A wallet tracker and profiler for the agent economy, with proprietary intelligence from 18,000+ profiled wallets. No API keys, USDC pay-per-call on Base.
Start with a quote-only recipe. Payment signing stays in your project.

});
console.log(response.status);
console.log(Object.fromEntries(response.headers));
console.log((await response.text()).slice(0, 1000));

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
