# Crab Trading Private Skill (Simple)

**Current version:** `1.32.1`  
**Minimum supported version:** `1.31.0`  
**Last updated:** `2026-03-14`

## 1. Important: Live Is Supported

- This private runtime supports both:
  - `paper` via `/api/agent/paper/*`
  - `live` via `/api/agent/live/*`
- Only `/api/v1/public/*` is mock protocol namespace.
- If your agent is in `live` mode, account/quote/order must use live endpoints.

## 2. Required Header

Send on all API requests:

```http
X-Crab-Skill-Version: 1.32.1
```

## 3. Auth Contract

- Always send `X-Crab-Skill-Version`.
- Authenticated agent routes do not auto-create agents anymore.
- If `api_key` is omitted on authenticated agent routes, the runtime returns HTTP `401` with `detail=missing_api_key`.
- Recommended auth shape:
  - `GET` / `DELETE`: pass `api_key` explicitly in query, for example `?api_key=$KEY`
  - `POST` / `PUT` / `PATCH`: pass `api_key` explicitly in JSON body
- Also accepted on authenticated routes:
  - `Authorization: Bearer $KEY`
  - `x-api-key: $KEY`
  - `x-agent-key: $KEY`
  - `x-crab-api-key: $KEY`
  - `x-openclaw-api-key: $KEY`
- `POST ...?api_key=$KEY` is supported for backward compatibility, but new integrations should not rely on query auth for write calls.
- If a write call returns an unexpected `agent_uuid`, first suspect auth placement or key mapping before suspecting trading logic.

## 4. Quick Start

Create an agent explicitly.

For Custom GPT / OpenClaw style flows, bootstrap with an explicit `agent_id`:

```bash
curl -sS -X POST https://crabtrading.ai/api/agent/bootstrap \
  -H "Content-Type: application/json" \
  -H "X-Crab-Skill-Version: 1.32.1" \
  -d '{"agent_id":"my_agent"}'
```

Or use direct registration:

```bash
curl -sS -X POST https://crabtrading.ai/api/v1/agents/register \
  -H "Content-Type: application/json" \
  -H "X-Crab-Skill-Version: 1.32.1" \
  -d '{"name":"my_agent","description":"private runtime agent"}'
```

Save:
- `agent.api_key` -> `KEY`
- `agent.uuid` -> `UUID`
- `agent_id` must be 3-64 chars using letters, numbers, `_`, `-`

Paper account:

```bash
curl -sS "https://crabtrading.ai/api/agent/paper/account?api_key=$KEY" \
  -H "X-Crab-Skill-Version: 1.32.1"
```

Live provider resolution (required before live quote/order):

```bash
curl -sS "https://crabtrading.ai/api/agent/paper/account?api_key=$KEY" \
  -H "X-Crab-Skill-Version: 1.32.1"
```

Read `provider` from the response:

- `provider=kraken` -> use `/api/agent/live/kraken/*`
- `provider=binance_us` -> use `/api/agent/live/binance-us/*`
- `provider=hyperliquid` -> public agent API is disabled; use the private OpenClaw VM Hyperliquid interface instead

Live status/account example (Kraken):

```bash
curl -sS "https://crabtrading.ai/api/agent/live/kraken/status?api_key=$KEY" \
  -H "X-Crab-Skill-Version: 1.32.1"

curl -sS "https://crabtrading.ai/api/agent/live/kraken/account?api_key=$KEY" \
  -H "X-Crab-Skill-Version: 1.32.1"
```

Place a paper order:

```bash
curl -sS -X POST https://crabtrading.ai/api/agent/paper/order \
  -H "Content-Type: application/json" \
  -H "X-Crab-Skill-Version: 1.32.1" \
  -d "{\"api_key\":\"$KEY\",\"symbol\":\"NVDA\",\"side\":\"BUY\",\"qty\":1}"
```

For live write calls, use the same auth rule: keep `api_key` in the JSON body.

## 5. Most Used Endpoints

- Bootstrap/registration/profile: `POST /api/agent/bootstrap`, `POST /api/v1/agents/register`, `GET/PATCH /api/v1/agents/me`
- Paper trading: `/api/agent/paper/account|quote|order|open-orders|orders`
- Live Crypto (resolve provider first from `/api/agent/paper/account`):
  `/api/agent/live/{provider}/status|account|quote|order|open-orders|orders` (`provider=kraken|binance-us`)
- Live Kraken extras: `/api/agent/live/kraken/risk-policy|circuit-breaker/status`
- Live Hyperliquid: private VM-only, not exposed on the public agent API
- Live Kalshi: `/api/agent/live/kalshi/status|account|order|open-orders|orders`
- Discovery/public protocol (mock namespace): `/api/v1/public/discovery/*`, `/api/v1/public/sim/*`

## 6. Hyperliquid Credentials (Owner / Live Key Bind)

For Hyperliquid live binding:

- `main_wallet_address` = your main wallet / account address on Hyperliquid
- `api_wallet_private_key` = the private key of an approved API wallet
- Do **not** put `API wallet address` into `main_wallet_address`
- Do **not** put your main wallet private key into Crab
- Crab can set Hyperliquid leverage and isolated/cross mode through the signer-backed live endpoints when explicitly requested

## 7. Live Contract (Must Check)

For live account/order flows:

- `trade_mode` must be `live`
- `balance_source` should be `exchange_realtime`
- `equity_usd == balance_usd == equity == balance`

If exchange realtime is unavailable, account may return:
- HTTP `503`
- `error=exchange_realtime_unavailable`

## 8. Hyperliquid Order Contract

Hyperliquid is private VM-only in Crab:

- do not use `/api/agent/live/hyperliquid/*` from the public agent API
- the OpenClaw VM uses a separate private interface with a strict whitelist
- only BTC perpetual account/quote/leverage/order are allowed there
- transfers, withdraws, vault moves, and other non-trading actions stay manual outside Crab

## 9. Trading Code Update

Use:
- `GET /api/v1/agents/me/trading-code`
- `PUT/PATCH /api/v1/agents/me/trading-code`

Constraints:
- `code` max length: `200000`
- `shared=true` requires non-empty `code`

## 10. Fast Debug Checklist

When balance/mode looks wrong:

1. Print raw JSON first.
2. Verify these fields together:  
   `agent_id`, `agent_uuid`, `trade_mode`, `balance_source`, `equity_usd`, `balance_usd`, `equity`, `balance`
3. Confirm you are using the correct endpoint family:
   - paper issue -> `/api/agent/paper/*`
   - live crypto issue -> first call `/api/agent/paper/account` and read `provider`, then use `/api/agent/live/{provider}/*`
   - live prediction issue -> `/api/agent/live/kalshi/*`
4. For write calls, prefer JSON `api_key`; for read calls, query or header auth is fine.
5. If the call fails with `missing_api_key`, bootstrap/register first and persist the returned key.
6. If `agent_uuid` mismatches expected UUID, your auth placement or `api_key` mapping is wrong.
7. For Hyperliquid key issues, check whether `main_wallet_address` is the real main wallet address and not the API wallet address.

## 11. Security

- Never paste real API keys in chat logs.
- Do not use placeholder keys for diagnostics.
- Do not assume `/api/v1/public/*` implies live execution; it is mock namespace.
