A command-line tool for the YellowPro cryptocurrency exchange.

Checking markets, prices, order books, balances, positions, funding, orders, and trades, plus placing or cancelling orders.

It gives an agent one way to view exchange data and account information, or trade when trading is enabled.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00656
Opus 5	$0.00028	$0.00328
Sonnet 5	$0.00011	$0.00131
Haiku 4.5	$0.00006	$0.00066

Measured 7d ago against content hash 517b586c5c90, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

yellow-pro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

yellow_pro exchange CLI

The yellow-pro CLI wraps the yellow_pro REST API. All output is raw exchange JSON. Prefer the yellow_pro MCP server when available; this CLI covers the same surface.

Requirements

Environment variables (already set if the MCP server is configured):

YELLOW_PRO_API_KEY, YELLOW_PRO_API_SECRET, YELLOW_PRO_APP_SESSION_ID — for account/trading commands
YELLOW_PRO_ENABLE_TRADING=true — required for place/cancel/leverage/transfer commands
YELLOW_PRO_BASE_URL — optional explicit URL override
YELLOW_PRO_SANDBOX=true — use staging (https://api.staging.yellow.pro.neodax.app); otherwise production (https://trade.api.yellow.pro)

Workflow

Discover markets first: yellow-pro markets — native ids look like ETHUSDT (spot) and BTCUSDT-PERP (perpetual). Check precision/filters before quoting amounts.
Market data: yellow-pro ticker <market>, yellow-pro orderbook <market>, yellow-pro klines <market> --interval 1h --limit 100, yellow-pro funding <market>
Account: yellow-pro balance spot or yellow-pro balance perp, yellow-pro open-orders perp, yellow-pro positions, yellow-pro trades perp --market <market>, yellow-pro fee-tier
Trading (amounts/prices are decimal strings). For both Spot and Perpetual markets, an order amount is quantity in the market's base asset: ETHUSDT uses ETH and BTCUSDT-PERP uses BTC. Prices use the market's quote asset. Label both values with their correct units when confirming.
- yellow-pro place perp BTCUSDT-PERP buy limit 0.001 65000 --leverage 5 --client-order-id my-id
- yellow-pro place spot ETHUSDT sell market 0.01
- yellow-pro cancel perp BTCUSDT-PERP <order_uuid>
- yellow-pro cancel-all perp --market BTCUSDT-PERP
- yellow-pro close-positions --market BTCUSDT-PERP
- yellow-pro set-leverage BTCUSDT-PERP 10
Run yellow-pro --help for the full command list.

Safety

Never place orders unless the user explicitly asked for them in this conversation.
Confirm market id, side, amount (quantity in the market's base asset), and price back to the user before placing an order.
If a trading command fails with "trading is disabled", tell the user to set YELLOW_PRO_ENABLE_TRADING=true — do not work around it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
