## 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-opensky-defi-intelligence-api-c37a8818
```

Example prompt: Pull the latest OpenSky protocol intelligence from SperaxOS — I want to see current DeFi metrics and positions, and pay the $0.001 USDC fee per call via x402 from my Base wallet.

## When to prefer this

Choose this endpoint when you need AI-powered intelligence specifically about the OpenSky DeFi protocol on Base, and want to pay per-request with USDC via x402 without managing API keys. Prefer this over traditional API-key-gated services when building autonomous agents that self-fund micropayments, or when you want zero onboarding friction for DeFi analytics on the Base network.

## Known failure modes

- Payment not included or insufficient USDC — returns 402 Payment Required with payment details
- Invalid or malformed properties filter — returns 400 Bad Request
- OpenSky protocol data temporarily unavailable — returns 503 or 500
- Wallet not recognized for identity-gated endpoints — returns 401 Unauthorized
- Rate limit exceeded — returns 429 Too Many Requests

## 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

Returns AI-powered DeFi intelligence data related to the OpenSky protocol, including on-chain metrics, protocol analytics, and relevant market data. The response is structured JSON reflecting the state of OpenSky on the Base network.
