## 原文

# Bankr

Execute crypto trading and DeFi operations using natural language. Two integration options:

1. **Bankr CLI** (recommended) — Install `@bankr/cli` for a batteries-included terminal experience
2. **REST API** — Call `https://api.bankr.bot` directly from any language or tool

Both use the same API key and the same async job workflow under the hood.

## Getting an API Key

Before using either option, you need a Bankr API key. Two ways to get one:

**Option A: Headless email login (recommended for agents)**

Two-step flow — send OTP, then verify and complete setup. See "First-Time Setup" below for the full guided flow with user preference prompts.

```bash
# Step 1 — send OTP to email
bankr login email user@example.com

# Step 2 — verify OTP and generate API key (options based on user preferences)
bankr login email user@example.com --code 123456 --accept-terms --key-name "My Agent" --read-write
```

This creates a wallet, accepts terms, and generates an API key — no browser needed. Before running step 2, ask the user whether they need read-only or read-write access, LLM gateway, and their preferred key name.

**Option B: Bankr Terminal**

1. Visit [bankr.bot/api](https://bankr.bot/api)
2. **Sign up / Sign in** — Enter your email and the one-time passcode (OTP) sent to it
3. **Generate an API key** — Create a key with **Agent API** access enabled (the key starts with `bk_...`)

Both options automatically provision **EVM wallets** (Base, Ethereum, Polygon, Unichain) and a **Solana wallet** — no manual wallet setup needed.

## Option 1: Bankr CLI (Recommended)

### Install

```bash
bun install -g @bankr/cli
```

Or with npm:

```bash
npm install -g @bankr/cli
```

### First-Time Setup

#### Headless email login (recommended for agents)

When the user asks to log in with an email, walk them through this flow:

**Step 1 — Send verification code**

```bash
bankr login email <user-email>
```

**Step 2 — Ask the user for the OTP code** they received via email.

**Step 3 — Before completing login, ask the user about their preferences:**

1. **Accept Terms of Service** — Present the [Terms of Service](https://bankr.bot/terms) link and confirm the user agrees. Required for new users — do not pass `--accept-terms` unless the user has explicitly confirmed.
2. **Read-only or read-write API key?**
   - **Read-only** (default) — portfolio, balances, prices, research only
   - **Read-write** (`--read-write`) — enables swaps, transfers, orders, token launches, leverage, Polymarket bets
3. **Enable LLM gateway access?** (`--llm`) — multi-model API at `llm.bankr.bot` (currently limited to beta testers). Skip if user doesn't need it.
4. **Key name?** (`--key-name`) — a display name for the API key (e.g. "My Agent", "Trading Bot")

**Step 4 — Construct and run the step 2 command** with the user's choices:

```bash
# Example with all options
bankr login email <user-email> --code <otp> --accept-terms --key-name "My Agent" --read-write --llm

# Example read-only, no LLM
bankr login email <user-email> --code <otp> --accept-terms --key-name "Research Bot"
```

#### Login options reference

| Option | Description |
|--------|-------------|
| `--code <otp>` | OTP code received via email (step 2) |
| `--accept-terms` | Accept [Terms of Service](https://bankr.bot/terms) without prompting (required for new users) |
| `--key-name <name>` | Display name for the API key (e.g. "My Agent"). Prompted if omitted |
| `--read-write` | Enable write operations: swaps, transfers, orders, token launches, leverage, Polymarket bets. **Without this flag, the key is read-only** (portfolio, balances, prices, research only) |
| `--llm` | Enable [LLM gateway](https://docs.bankr.bot/llm-gateway/overview) access (multi-model API at `llm.bankr.bot`). Currently limited to beta testers |

Any option not provided on the command line will be prompted interactively by the CLI, so you can mix headless and interactive as needed.

#### Login with existing API key

If the user already has an API key:

```bash
bankr login --api-key bk_YOUR_KEY_HERE
```

If they need to create one at the Bankr Terminal:
1. Run `bankr login --url` — prints the terminal URL
2. Present the URL to the user, ask them to generate a `bk_...` key
3. Run `bankr login --api-key bk_THE_KEY`

#### Separate LLM Gateway Key (Optional)

If your LLM gateway key differs from your API key, pass `--llm-key` during login or run `bankr config set llmKey YOUR_LLM_KEY` afterward. When not set, the API key is used for both. See [references/llm-gateway.md](references/llm-gateway.md) for full details.

#### Verify Setup

```bash
bankr whoami
bankr prompt "What is my balance?"
```

## Option 2: REST API (Direct)

No CLI installation required — call the API directly with `curl`, `fetch`, or any HTTP client.

### Authentication

All requests require an `X-API-Key` header:

```bash
curl -X POST "https://api.bankr.bot/agent/prompt" \
  -H "X-API-Key: bk_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "What is my ETH balance?"}'
```

### Quick Example: Submit → Poll → Complete

```bash
# 1. Submit a prompt — returns a job ID
JOB=$(curl -s -X POST "https://api.bankr.bot/agent/prompt" \
  -H "X-API-Key: $BANKR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "What is my ETH balance?"}')
JOB_ID=$(echo "$JOB" | jq -r '.jobId')

# 2. Poll until terminal status
while true; do
  RESULT=$(curl -s "https://api.bankr.bot/agent/job/$JOB_ID" \
    -H "X-API-Key: $BANKR_API_KEY")
  STATUS=$(echo "$RESULT" | jq -r '.status')
  [ "$STATUS" = "completed" ] || [ "$STATUS" = "failed" ] || [ "$STATUS" = "cancelled" ] && break
  sleep 2
done

# 3. Read the response
echo "$RESULT" | jq -r '.response'
```

### Conversation Threads

Every prompt response includes a `threadId`. Pass it back to continue the conversation:

```bash
# Start — the response includes a threadId
curl -X POST "https://api.bankr.bot/agent/prompt" \
  -H "X-API-Key: $BANKR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "What is the price of ETH?"}'
# → {"jobId": "job_abc", "threadId": "thr_XYZ", ...}

# Continue — pass threadId to maintain context
curl -X POST "https://api.bankr.bot/agent/prompt" \
  -H "X-API-Key: $BANKR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "And what about SOL?", "threadId": "thr_XYZ"}'
```

Omit `threadId` to start a new conversation. CLI equivalent: `bankr prompt --continue` (reuses last thread) or `bankr prompt --thread <id>`.
