## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability speraxos-sentiment-agent-88042200
```

Example prompt: What's the current market sentiment on Sperax's DeFi ecosystem — is it bullish or bearish right now? Pay the $0.005 USDC fee to get the AI sentiment agent's read.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
