# Morning market brief

> Chain CoinGecko + NewsAPI + Anthropic over x402. Three paid calls, ~$0.06, zero API keys.

Your agent pulls live prices from CoinGecko, top crypto headlines from NewsAPI, and asks Claude to write a 200-word brief — all paid in USDC on the [`mpp.t2000.ai`](https://mpp.t2000.ai) gateway. No subscriptions, no auth setup.

***

## The prompt

```
Use t2 services. Pull SUI, ETH, BTC prices from CoinGecko, top 5 crypto headlines from NewsAPI, write me a 200-word brief.
```

***

## What runs

1. `POST /coingecko/v1/price` — coins by ID vs USD
2. `POST /newsapi/v1/search` — keyword article search
3. `POST /anthropic/v1/messages` — Claude Sonnet stitches them into prose

Each call returns HTTP 402, your wallet signs a tiny USDC payment, the gateway proxies upstream and returns 200. Total \~\$0.06, \~6s end to end.

***

## Run it

### Claude Desktop (MCP)

Install the wallet, wire MCP, fund \$1 of USDC, paste the prompt:

```bash theme={null}
npm install -g @t2000/cli
t2 init
t2 fund          # send $1 USDC to this address
t2 mcp install      # auto-wires Claude Desktop, Cursor, Windsurf
```

The MCP server's `t2000_pay` tool handles the 402s automatically — Claude makes the calls and writes the brief.

### CLI

```bash theme={null}
PRICES=$(t2 pay https://mpp.t2000.ai/coingecko/v1/price \
  --data '{"ids":"sui,ethereum,bitcoin","vs_currencies":"usd"}')

NEWS=$(t2 pay https://mpp.t2000.ai/newsapi/v1/search \
  --data '{"q":"crypto","pageSize":5}')

t2 pay https://mpp.t2000.ai/anthropic/v1/messages \
  --header 'anthropic-version: 2023-06-01' \
  --data "{\"model\":\"claude-sonnet-4-5\",\"max_tokens\":1024,\"messages\":[{\"role\":\"user\",\"content\":\"Prices: $PRICES. Headlines: $NEWS. Write a 200-word brief.\"}]}"
```

### SDK

```typescript theme={null}
import { T2000 } from '@t2000/sdk';

const agent = await T2000.create();

const prices = await agent.pay({
  url: 'https://mpp.t2000.ai/coingecko/v1/price',
  method: 'POST',
  body: JSON.stringify({ ids: 'sui,ethereum,bitcoin', vs_currencies: 'usd' }),
});

const news = await agent.pay({
  url: 'https://mpp.t2000.ai/newsapi/v1/search',
  method: 'POST',
  body: JSON.stringify({ q: 'crypto', pageSize: 5 }),
});

const brief = await agent.pay({
  url: 'https://mpp.t2000.ai/anthropic/v1/messages',
  method: 'POST',
  headers: { 'anthropic-version': '2023-06-01' },
  body: JSON.stringify({
    model: 'claude-sonnet-4-5',
    max_tokens: 1024,
    messages: [{
      role: 'user',
      content: `Prices: ${JSON.stringify(prices.body)}. Headlines: ${JSON.stringify(news.body)}. Write a 200-word brief.`,
    }],
  }),
});
```

## Expected output

```
3 calls · ~$0.06 · ~6s · 0 taps
```

A 200-word morning brief stitched from live data.

## Extend it

* Swap NewsAPI for **Exa** (`/exa/v1/search`) for AI-native semantic search
* Add **Alpha Vantage** (`/alphavantage/v1/quote`) to pull a few equities alongside crypto
* Pipe the brief to a TTS endpoint (**ElevenLabs** `/v1/text-to-speech/:voiceId`) and play it on a morning kitchen speaker
* Schedule via cron or GitHub Actions — every call is stateless and pays itself
