About AA Signals

The first x402-settled trading signal API, live on Base mainnet.

What we do

AA Signals delivers real-time crypto trading signals (BUY / SELL / HOLD) for 8 symbols via the x402 payment protocol. Each signal includes confidence scores, market regime analysis, and Kraken-verified order book data.

Why x402?

Traditional trading APIs lock you into subscriptions. AA Signals is different: you pay $0.05 USDC per signal, settled on-chain in ~2 seconds. No contracts. No lock-in. No API keys.

How it works

1. Make an API call to /v1/signal/{symbol}
2. Receive HTTP 402 with payment terms
3. Send 0.05 USDC to our address on Base
4. Retry with proof-of-settlement → get the signal
