# Moltalyzer API v3.2.0 — Complete Reference

> Five AI intelligence feeds in one API: Moltbook community analysis, GitHub trending repos, Polymarket predetermined outcome detection, real-time token intelligence, and Pulse cross-source narrative intelligence. All /latest endpoints are free (rate-limited). Historical data and signal feeds use x402 (USDC on Base, no account required).

Moltalyzer analyzes thousands of AI agent posts per hour on Moltbook, scans GitHub daily for trending new repositories, detects predetermined-outcome opportunities on Polymarket, runs continuous token intelligence with hybrid rule+LLM scoring, and tracks cross-source narratives via Pulse. All /latest endpoints are free (1 req/5min per IP).

| GET /api/polymarket/signals?since=N&count=5&confidence=high | $0.03 USDC | Batch up to 20 signals — filterable |

### Token Intelligence (Real-Time Signal Feed)

| Endpoint | Price | Description |
|----------|-------|-------------|
| GET /api/tokens/index | Free | Current signal index — poll to detect new signals |
| GET /api/tokens/sample | Free | One 24hr+ old signal for testing (rate-limited 1 req/20min) |

**How the signal feed works:**
1. Every completed token analysis gets a sequential `signalIndex` (1, 2, 3, ...)
2. Poll `GET /api/tokens/index` (free) to get the current index number
3. When the index increments, pay to fetch new signal(s)
4. Pass `?since=N` to `/signals` to get only tokens after index N
5. Each returned token includes its `signalIndex` so you can track your position

## Payment: x402 Protocol

This API uses x402 — an open HTTP payment protocol. Paid endpoints respond with HTTP 402 on first request. An x402 client library handles payment automatically: it reads the 402 response, signs a USDC transfer authorization with your wallet, and retries.

**Requirements:**
- An EVM wallet private key (any Ethereum-compatible wallet)
- USDC on Base Mainnet (Chain ID 8453) — even $1 lasts 200 requests
- An x402 client library

**Supported wallet environment variables:**

| Variable | Used by |
|----------|---------|
| EVM_PRIVATE_KEY | Coinbase x402 official, ClawHub skills, ElizaOS |
| PRIVATE_KEY | ERC-8004 SDK, x402 starter kit |
| BLOCKRUN_WALLET_KEY | ClawRouter |
| WALLET_PRIVATE_KEY | Virtuals Protocol ACP |

### TypeScript Setup

```bash
npm install @x402/fetch @x402/evm viem
```

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

const key = process.env.EVM_PRIVATE_KEY
  || process.env.PRIVATE_KEY
  || process.env.BLOCKRUN_WALLET_KEY
  || process.env.WALLET_PRIVATE_KEY;

if (!key) throw new Error("No wallet key found. Set EVM_PRIVATE_KEY.");

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

// Make a paid request
const response = await fetchWithPayment(
  "https://api.moltalyzer.xyz/api/moltbook/digests/latest"
);
const { data } = await response.json();

console.log(`Topics: ${data.topTopics.join(", ")}`);
console.log(`Sentiment: ${data.overallSentiment}`);
console.log(`Emerging: ${data.emergingNarratives.join(", ")}`);
```

### Python Setup

```bash
pip install "x402[httpx]" eth_account
```

```python
import asyncio
import os
from eth_account import Account
from x402 import x402Client
from x402.http.clients import x402HttpxClient
from x402.mechanisms.evm import EthAccountSigner
from x402.mechanisms.evm.exact.register import register_exact_evm_client

key = (os.getenv("EVM_PRIVATE_KEY")
    or os.getenv("PRIVATE_KEY")
    or os.getenv("BLOCKRUN_WALLET_KEY")
    or os.getenv("WALLET_PRIVATE_KEY"))

if not key:
    raise ValueError("No wallet key found. Set EVM_PRIVATE_KEY.")

async def main():
    client = x402Client()
    account = Account.from_key(key)
    register_exact_evm_client(client, EthAccountSigner(account))

    async with x402HttpxClient(client) as http:
        response = await http.get(
            "https://api.moltalyzer.xyz/api/moltbook/digests/latest"
        )
        data = response.json()["data"]
        print(f"Topics: {data['topTopics']}")
        print(f"Sentiment: {data['overallSentiment']}")

asyncio.run(main())
```

### Payment Flow (Under the Hood)

1. Your code calls `fetchWithPayment("https://api.moltalyzer.xyz/api/moltbook/digests/latest")`
2. Server responds with `402 Payment Required` + `PAYMENT-REQUIRED` header
3. x402 library reads the header, signs a USDC transfer with your wallet
4. Library retries the request with a `PAYMENT-SIGNATURE` header
5. Server verifies payment, settles USDC on-chain, returns data with `PAYMENT-RESPONSE` header

All of this happens in a single `await` from your perspective.

  "totalToday": 3
}
```

6. Store lastSeen = 14
7. Repeat from step 3
```

### GET /api/tokens/signals

Returns up to 20 token signals. Use `?since=N` to get only signals after a specific index — this is the primary polling pattern. Costs **$0.05 USDC** per request.

**Query parameters:**

| Parameter | Type | Default | Range | Description |
|-----------|------|---------|-------|-------------|
| since | integer | - | 0+ | Get signals after this index (most useful for polling) |
| count | integer | 5 | 1-20 | Max signals to return |
| chain | string | - | - | Filter by chain: ethereum, base, solana (no longer actively scanned), bsc |
| tier | string | - | - | Filter by tier: meme, longterm |
| minScore | integer | 0 | 0-100 | Minimum hybrid score |

**Response (200):**

```json
{
  "success": true,
  "count": 3,
  "filters": {
    "since": 127,
    "count": 5,
    "chain": "all",
    "tier": "all",
    "minScore": 0
  },
  "data": [
    {
      "signalIndex": 128,
      "symbol": "TOKEN",
      "name": "Token Name",
      "chainId": "base",
      "hybridScore": 55,
      "tier": "meme",
      "llmDescription": "...",
      "llmRiskLevel": "high",
      "llmRedFlags": ["..."],
      "llmGreenFlags": ["..."],
      "backtests": [...]
    }
  ]
}
```

**Note:** `/signals` returns the standard signal format (without the deep detail fields like score breakdown and reasoning). Use `/signal?index=N` to get full detail for a specific token.

### GET /api/tokens/history

Returns historical token signals within a date range. Paginated, max 7-day range per request. Costs **$0.03 USDC** per request.

**Query parameters:**

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| from | string | - | Start date (ISO or YYYY-MM-DD, inclusive). **Required.** |
| to | string | now | End date (ISO or YYYY-MM-DD, exclusive) |
| chain | string | - | Filter by chain: ethereum, base, solana (no longer actively scanned), bsc |
| tier | string | - | Filter by tier: meme, longterm |
| minScore | integer | 0 | Minimum hybrid score 0-100 |
| page | integer | 1 | Page number |
| limit | integer | 20 | Results per page, 1-100 |

**Response (200):**

```json
{
  "success": true,
  "count": 20,
  "totalCount": 45,
  "page": 1,
  "totalPages": 3,
  "filters": {
    "from": "2026-02-20T00:00:00.000Z",
    "to": "2026-02-24T00:00:00.000Z",
    "chain": "all",
    "tier": "all",
    "minScore": 0
  },
  "data": [
    { /* same signal format as /signals */ }
  ]
}
```

**Polling pattern:**
```
1. GET /api/tokens/index → { index: 130 }     (free)
2. Store lastSeen = 130
3. ... wait ...
4. GET /api/tokens/index → { index: 133 }     (free)
5. GET /api/tokens/signals?since=130&count=20  ($0.05, returns signals 131-133)
6. Store lastSeen = 133
7. Repeat from step 3
```
