## 1. Create an account

Open the [dashboard](https://www.f1ow.com/dashboard) and sign in with Google, X, GitHub, Telegram, a passkey or MetaMask. A new account starts a free trial straight away: **7 days and 500 tool calls**, whichever runs out first. No card is required.

## 2. Pick how you connect

| You use | Connect with | Guide |
| --- | --- | --- |
| Claude (web, desktop) | OAuth, one click | [Claude](https://www.f1ow.com/docs/connect/claude) |
| ChatGPT | API key header | [ChatGPT](https://www.f1ow.com/docs/connect/chatgpt) |
| Cursor | API key in `mcp.json` | [Cursor](https://www.f1ow.com/docs/connect/cursor) |
| VS Code / GitHub Copilot | API key in `mcp.json` | [VS Code](https://www.f1ow.com/docs/connect/vscode) |
| Your own code or agent | MCP, REST or WebSocket | [Custom agents](https://www.f1ow.com/docs/connect/custom-agent) |
| An agent with a wallet, no account | x402 pay-per-call | [Authentication](https://www.f1ow.com/docs/auth#x402) |

For Claude, select [Add to Claude](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=f1ow&connectorUrl=https%3A%2F%2Fmcp.f1ow.com%2Fmcp) to open a prefilled connector form; see the [Claude guide](https://www.f1ow.com/docs/connect/claude) for the manual fallback. Claude runs the OAuth sign-in for you. Everything else takes an **API key**: create one in the dashboard under *API keys*. The key is shown once, so copy it somewhere safe.

## 3. Make your first call

In Claude or ChatGPT, just ask:

> What is the market regime right now, and who is crowded on BTC?

The model picks [Market Regime](https://www.f1ow.com/docs/tools/research_regime) and [Positioning](https://www.f1ow.com/docs/tools/research_positioning) on its own.

From code, call the REST API with your key:

```bash
curl "https://mcp.f1ow.com/v1/research/regime" \
  -H "Authorization: Bearer $F1OW_API_KEY"
```

Every response carries `text`, the report written for a model to read. Most tools also return `data` with the same result as JSON, and `meta.generatedAt` tells you how fresh it is.

## 4. Keep going

When the trial ends, $49 buys 30 days and 12,500 calls. You can pay by USDC or USDT on Base, Arbitrum, Polygon or Ethereum. See [pricing & limits](https://www.f1ow.com/docs/pricing-limits).
