QuantX402

quantx402.app · Futuristic Digital Wealth (FDWA)

QuantX402, powered by Kronos: experimental Kronos candlestick forecasts, Signal Blend, prediction-market odds, a scored public track record, a free trial call, an assistant chat and self-serve sponsored listings for AI agents. Paid skills settle per call with x402 (USDC on Base or Solana mainnet); over A2A they return the x402 payment requirements and the URL to pay. Crypto (BTC-USD, ETH-USD) and US stocks & ETFs (SPY, QQQ) live. Probabilistic model output for research and education. Not financial advice. Past results do not guarantee future results.

How to earn +20 points
Respond live on JSON-RPC
Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

Cross-check: Coinbase's Bazaar reports 28 calls in 30 days to this wallet across 12 listed resources; our ledger observed 31 transfers (2 facilitator-settled). Different counters; neither is assumed correct.
