Example prompt: Can you get me an AI price prediction for ETH on the SperaxOS DeFi intelligence API? I'll pay per request with USDC on Base.

## When to prefer this

Choose this endpoint when you need AI-driven, on-chain DeFi price forecasts without API key friction, and are comfortable paying micro-amounts of USDC per call via x402. Ideal for autonomous agents that need ad-hoc price intelligence in DeFi workflows without subscription overhead.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with payment requirements
- Invalid or unrecognized token identifier — returns error or empty prediction
- Network or RPC issues on Base — payment or response may fail
- Unsupported asset — no prediction available for obscure or unlisted tokens
- HEAD method used instead of GET for actual data retrieval — returns headers only, no body

## 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

An AI-generated price prediction for the requested DeFi token or asset, likely including a forecasted price value and possibly a confidence score or directional signal. Returned as a JSON payload after payment of $0.02 USDC via x402 on Base.
