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 sentiment assessment for DeFi markets or a specific asset, including a directional signal (bullish/bearish/neutral) and supporting intelligence. Delivered as a structured response after a $0.005 USDC x402 micropayment is processed on Base.
Example use cases
Token investment sentiment check
“Before I add more to my DeFi position, can you pull the AI sentiment agent's read on the current market mood? I want to know if it's bullish or bearish right now.”
Protocol health monitoring
“I'm monitoring a DeFi protocol and want to know what the sentiment agent says about the current market feeling around it — is it positive, negative, or neutral?”
DeFi trading signal for bot
“Run the SperaxOS sentiment agent and tell me the current DeFi sentiment score so my trading bot can decide whether to open or close a position.”
Technical details
Endpoint
GEThttps://chat.sperax.io/api/x402/intel/sentiment-agent?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time AI-driven DeFi sentiment without managing API keys — ideal for autonomous agents that can pay per-call with USDC on Base. Prefer this over traditional sentiment APIs when operating in a crypto-native, permissionless context where x402 micropayments are already part of the agent's payment stack.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid or malformed properties input — may return 400 or empty result
- Network or blockchain congestion delaying x402 payment confirmation
- Wallet lacks agentcash identity for free SIWX endpoints — this paid endpoint still requires micropayment
- Service unavailable or rate limits on the underlying AI intelligence layer
