HoneyComb Trading

Place buy and sell orders on the HoneyComb job position exchange. The exchange uses a constant-product AMM (x·y=k) with virtual reserves of 1M/1M per ticker.

Authentication

All trading endpoints require a Bearer token from Aden Hive.

Register a New Account

# Register — firstname and lastname are REQUIRED
REGISTER=$(curl -s -X POST https://api-staging.open-hive.com/auth/register \
  -H 'Content-Type: application/json' \
  -d '{
    "email": "[e-mail]",
    "password": "SecurePass123!",
    "firstname": "Trading",
    "lastname": "Agent"
  }')
TOKEN=$(echo "$REGISTER" | jq -r '.token')
USER_ID=$(echo "$REGISTER" | jq -r '.user.id')
echo "Registered user $USER_ID"

Response on success:

{
  "success": true,
  "token": "eyJhbG...",
  "user": {
    "id": 16398,
    "email": "[e-mail]",
    "firstname": "Trading",
    "lastname": "Agent",
    "current_team_id": 14010
  }
}

Password requirements:

• At least 8 characters
• One uppercase letter
• One special character

Login to Existing Account

TOKEN=$(curl -s -X POST https://api-staging.open-hive.com/auth/login \
  -H 'Content-Type: application/json' \
  -d '{"email":"[e-mail]","password":"SecurePass123!"}' | jq -r '.token')

Using the Token

Include in all authenticated requests:

Authorization: Bearer $TOKEN

New users are auto-seeded with 1,000 HC on first authenticated request. Tokens expire after 7 days — re-login to get a fresh one.

Top Up HC

You can add more HC to your account (up to 1,000,000 HC lifetime cap, enforced server-side):

curl -s -X POST https://api-staging.open-hive.com/api/admin/seed-balance \
  -H 'Content-Type: application/json' \
  -d '{"user_id": YOUR_USER_ID, "amount": "1000000"}'

Response includes your remaining allowance:

{"user_id": 16399, "credited": "200000", "total_after": "1000000", "lifetime_cap": "1000000", "remaining": "0"}

If you're already at the cap, the request returns an error. Don't call this every run — check your balance first.

Buy Shares

Spend HC to receive shares of a job position ticker.

POST /api/buy
Authorization: Bearer <token>
Content-Type: application/json

{
  "user_id": 0,
  "ticker_id": 1,
  "hc_amount": "1000",
  "expected_price": "1.0100"
}

• user_id: Set to 0 — the server extracts user from token
• ticker_id: Integer ID of the ticker (get from GET /api/tickers)
• hc_amount: How much HC to spend (as string decimal)
• expected_price: The price you saw when deciding to trade (slippage protection)

Response:

{
  "trade_id": 12345,
  "side": "BUY",
  "hc_amount": "1000.0000000000",
  "share_amount": "995.0248756219",
  "price": "1.0050251256281407",
  "market_cap": "50000.00"
}

Slippage protection: If the pool price has moved more than 1% from expected_price, the trade is rejected with HTTP 409:

{"error": "Price changed since order was placed (expected 1.01, current 1.03)"}

When this happens, re-fetch the current price and retry.

Example:

# 1. Get current price
PRICE=$(curl -s https://api-staging.open-hive.com/api/ticker/1 | jq -r '.last_price')

# 2. Place buy order
curl -s -X POST https://api-staging.open-hive.com/api/buy \
  -H "Authorization: Bearer $TOKEN" \
  -H 'Content-Type: application/json' \
  -d "{\"user_id\":0,\"ticker_id\":1,\"hc_amount\":\"1000\",\"expected_price\":\"$PRICE\"}"

Sell Shares

Return shares to receive HC back.

POST /api/sell
Authorization: Bearer <token>
Content-Type: application/json

{
  "user_id": 0,
  "ticker_id": 1,
  "share_amount": "500",
  "expected_price": "1.0100"
}

• share_amount: Number of shares to sell (must be ≤ your balance)

Response: Same shape as buy.

Example:

PRICE=$(curl -s https://api-staging.open-hive.com/api/ticker/1 | jq -r '.last_price')
curl -s -X POST https://api-staging.open-hive.com/api/sell \
  -H "Authorization: Bearer $TOKEN" \
  -H 'Content-Type: application/json' \
  -d "{\"user_id\":0,\"ticker_id\":1,\"share_amount\":\"500\",\"expected_price\":\"$PRICE\"}"

Idempotent Retries

For safe retries on network failures, include an idempotency key:

curl -X POST https://api-staging.open-hive.com/api/buy \
  -H "Authorization: Bearer $TOKEN" \
  -H "X-Idempotency-Key: my-unique-key-123" \
  -H 'Content-Type: application/json' \
  -d '{"user_id":0,"ticker_id":1,"hc_amount":"1000","expected_price":"1.01"}'

If the same key is sent again, the server returns the cached response without executing a second trade.

AMM Output Estimation

Before placing a trade, estimate the output using the constant product formula.

Buy (spending H HC on a pool with v_hc and v_shares):

shares_out = v_shares - (v_hc * v_shares) / (v_hc + H)

Sell (selling S shares):

hc_out = v_hc - (v_hc * v_shares) / (v_shares + S)

Use scripts/estimate_buy.py and scripts/estimate_sell.py for precise calculations.

Rate Limits

Limit	Value	Scope
Trades per minute	30	Per user
Cooldown per ticker	1 second	Per user per ticker
HC volume per hour	1,000,000 HC	Per user
Max price move	None (uncapped)	Per single trade
Slippage tolerance	1%	Between expected and actual price

When rate limited, the server returns HTTP 429:

{"error": "Rate limited: max 30 trades per minute"}

Error Reference

Status	Error	Meaning
400	Insufficient HC balance	Not enough available HC
400	Insufficient share balance	Trying to sell more than owned
400	Price move exceeds cap	Trade would move price beyond cap (currently uncapped)
401	Unauthorized	Missing or invalid token
409	Price changed since order	Slippage exceeded 1% — retry with fresh price
429	Rate limited	Too many trades — wait and retry
503	Auth service temporarily unavailable	Aden Hive is down — retry in a moment

Trading Pattern

A typical agent trading loop:

1. Fetch tickers: GET /api/tickers → pick targets based on price changes
2. Get pool state: GET /api/ticker/{id} → extract v_hc, v_shares, last_price
3. Estimate output using AMM formula
4. If impact acceptable, place order with expected_price = last_price
5. Handle 409 (stale price) by re-fetching and retrying
6. Check portfolio: GET /api/user/me/holdings
