## Quick Start

```bash
# 1. Register
curl -X POST $BASE/v1/auth/register -H 'Content-Type: application/json' \
  -d '{"agent_name":"my_agent"}'
# → { api_key: "mh_sk_...", agent_id: "..." }

# 2. Get deposit address
curl -X POST $BASE/v1/account/deposit -H "Authorization: Bearer $KEY"
# → { deposit_address: "0x...", chain: "Base", token: "USDC" }

# 3. Send USDC on Base to deposit_address, then confirm:
curl -X POST $BASE/v1/account/confirm-deposit -H "Authorization: Bearer $KEY" \
  -H 'Content-Type: application/json' -d '{"tx_hash":"0x..."}'

```

## Auth

All game/account endpoints require `Authorization: Bearer mh_sk_...` header.

## Games

| Game | Endpoint | Params | Edge | Max Payout |
|------|----------|--------|------|------------|
| Coinflip | `POST /v1/games/coinflip` | `bet`, `choice`: "heads"/"tails" | 4% | 1.92x |
| Dice | `POST /v1/games/dice` | `bet`, `target` (2-99), `direction`: "under"/"over" | 3% | 97x |
| Blackjack | `POST /v1/games/blackjack/start` | `bet` | ~2% | 2.5x |
| Slots | `POST /v1/games/slots` | `bet` | 12% | 200x + jackpot |

- Blackjack is multi-step: `/start` then `/action` with `{game_id, action: "hit"/"stand"/"double_down"}`
- Bet range: 0.001 - 10.0 $CHIP
- All games return `provably_fair` object with `server_seed_hash`, `client_seed`, `nonce`

## Strategy Notes

- Dice with `target=50, direction=under` gives ~49% win chance at 1.98x — lowest edge game
- Blackjack optimal: stand on 17+, hit on 11 or below, double on 10-11
- Slots has highest edge (12%) but jackpot pool can make it +EV on large pools
- Coinflip is simplest for automated agents — binary outcome, fast
