Chainup Spot Trading

ChainUp/OpenAPI V2 spot and margin trading skill. Prefer using the Python script to call sapi endpoints through one unified entrypoint and avoid ad hoc signing logic.

ChainUp Spot (Script-First)

Why This Skill

Use this skill immediately when the user mentions OpenAPI V2, spot trading, margin trading, X-CH-SIGN, /sapi/v2/order, /sapi/v1/margin/*, /sapi/v1/account, or similar ChainUp trading/account scenarios.

Goals:

• Prefer the script entrypoint instead of rebuilding signing logic each time.
• Return raw exchange JSON by default.
• If some parameters are still unknown, keep placeholders (TODO) first and let the user fill them in later.
• After the skill triggers, move to the script call quickly and avoid unnecessary explanation, extra reasoning, or repeated confirmation.

Runtime Entry

Unified entry script:

• scripts/chainup_api.py

Core capabilities:

• Built-in signing: X-CH-APIKEY, X-CH-SIGN, X-CH-TS
• Built-in common headers: Content-Type, admin-language, User-Agent
• Unified action -> endpoint mapping
• Real balance-changing actions require --confirm CONFIRM by default
• Order actions support --prepare-only: fetch symbol rules via spot_symbols first, then preprocess price / volume
• Supports --show-todo to display unresolved required placeholders for the current action

Execution Rules

• When this skill is triggered, call scripts/chainup_api.py first. Do not restate API parameter planning in natural language before using the script.
• For read-only actions that do not affect balances or order state, call the script directly once parameters are clear. Only ask follow-up questions when required parameters are missing and cannot be inferred safely.
• For any action that can change balances, positions, open orders, or fills, provide a short execution summary in natural language before the live request, then wait for the user to reply with an exact standalone Confirm before calling the script.
• For non-fund-changing queries, avoid extra confirmation and execute directly.
• Do not treat "the user wants to place/cancel/transfer" as execution permission. No live request is allowed until a separate user message contains Confirm.
• For spot_create_order, spot_test_order, and margin_create_order, run the script with --prepare-only before asking for confirmation. The script will call spot_symbols, fetch symbol precision, and round down using pricePrecision / quantityPrecision.
• When showing parameters that need confirmation, always use the preparedBody from --prepare-only. Do not show the unadjusted raw order payload.
• After the user sends a standalone Confirm, execute the live balance-changing action and keep using --confirm CONFIRM.
• If spot_create_order succeeds, follow up with spot_get_order by default.
• All HTTP requests must be sent through scripts/chainup_api.py.
• If the script call fails, return the script failure result and continue debugging through the Python script only. Do not switch to curl, handwritten signing, or any backup HTTP implementation.
• Do not add a second implementation "just to verify the API". Avoid branching logic and duplicated reasoning.

Required Config

Prefer /root/TOOLS.md first:

• BASE_URL: ...
• API_KEY: ...
• SECRET_KEY: ...

Use environment variables only as the next fallback:

• CHAINUP_BASE_URL
• CHAINUP_API_KEY
• CHAINUP_SECRET_KEY

CLI arguments are also supported:

• --base-url
• --api-key
• --secret-key

Config resolution priority:

• CLI arguments > /root/TOOLS.md > environment variables
• If /root/TOOLS.md already contains usable credentials, use them directly and do not require the user to set environment variables first.

Sensitive data handling:

• CHAINUP_API_KEY and CHAINUP_SECRET_KEY are sensitive. Never print them in full in the terminal, natural-language responses, execution summaries, error relays, or example commands.
• If they must be referenced, only show masked values: keep the first 4 and last 4 characters and replace the middle with ***, for example 915c***815e.
• Avoid inlining secrets in visible commands whenever possible. If a command must include them, do not repeat that full secret-bearing command in the response.
• Even if the user provides the full secret explicitly, never echo it back verbatim later.

Call Template

bash

python /root/.codex/skills/chainup-spot/scripts/chainup_api.py <action> \
  --query-json '<json-object>' \
  --body-json '<json-object>' \
  --show-todo

Notes:

• Use --query-json for GET actions
• Use --body-json for POST actions
• For order actions, --prepare-only can be used first to return precision-adjusted preparedBody for confirmation
• For actions that change balances or orders, append --confirm CONFIRM only after the user sends a standalone Confirm
• Unless the user asks for explanation, prefer executing first and returning the result instead of giving a long preface

Response Rules

• Return raw JSON by default (script stdout).
• --prepare-only returns originalBody, preparedBody, adjustments, and symbolRule so the user can review the precision-adjusted live order payload before confirmation.
• After a successful spot_create_order, immediately follow with spot_get_order by default and return the latest order details.
• When fetching the follow-up order, prefer symbol + orderId from the create-order response. If the gateway also returns orderIdString, preserve it as well.
• spot_account is filtered directly in the Python script and returns only assets where free > 0 or locked > 0.
• Add a short summary only when the user asks to "show just the key points".
• If returned content, errors, or debug output contains full api-key, secret-key, or other credentials, mask them before showing anything.

Safety Rules

• All live balance-changing actions (place order, cancel order, transfer) require the user to send Confirm manually before execution, then use --confirm CONFIRM.
• Any action that affects balances, even if it may not fill immediately, is still treated as a live balance-changing action. This includes but is not limited to limit orders, batch orders, cancellations, transfers, margin orders, and margin cancellations.
• Query actions can execute directly, including but not limited to balance queries, order queries, trade history queries, market data queries, and open-order queries.
• Precision prechecks are mandatory before order confirmation so the script does not send prices or quantities that exceed symbol precision to the live gateway.
• If the user explicitly requests to bypass confirmation, --no-confirm-gate may be used. This is high risk and should only be used with explicit user authorization.
• Never print full credentials in the terminal or reply. If the script throws an error that could expose secrets, summarize the failure rather than copying the raw sensitive output.

Examples

Query spot balances:

bash

python /root/.codex/skills/chainup-spot/scripts/chainup_api.py spot_account --query-json '{}'

Spot market order preparation (live request requires confirmation):

bash

python /root/.codex/skills/chainup-spot/scripts/chainup_api.py spot_create_order \
  --body-json '{"symbol":"BTC/USDT","volume":"100.123456","side":"BUY","type":"MARKET"}' \
  --prepare-only

Execute the live request after confirmation:

bash

python /root/.codex/skills/chainup-spot/scripts/chainup_api.py spot_create_order \
  --body-json '{"symbol":"BTC/USDT","volume":"100","side":"BUY","type":"MARKET"}' \
  --confirm CONFIRM --show-todo

Additional spot order conventions:

• When type=MARKET and side=BUY, volume is interpreted in the quote asset.
• For example, for ETH/USDT, volume=1 with side=BUY means buying ETH with 1 USDT at market.
• When type=MARKET and side=SELL, volume is interpreted in the base asset amount.
• For example, for ETH/USDT, volume=0.1 with side=SELL means selling 0.1 ETH at market.
• For non-market order types such as LIMIT, volume is still interpreted as the base asset amount.
• After spot_create_order succeeds, the default next step is not just returning the order receipt. The script should continue with spot_get_order and return the latest order information.

Margin limit order:

bash

python /root/.codex/skills/chainup-spot/scripts/chainup_api.py margin_create_order \
  --body-json '{"symbol":"BTC/USDT","volume":"0.001","side":"BUY","type":"LIMIT","price":"30000"}' \
  --confirm CONFIRM --show-todo
