pmls 0.2.0

Polymarket CLI utilities

pmls — Polymarket CLI

A Python CLI for reading and trading on Polymarket prediction markets via the CLOB and GAMMA APIs.

---

Installation

pip install pmls

Requires Python ≥ 3.11.

---

Environment Variables

Create a .env file in the working directory (loaded automatically via python-dotenv).

Variable	Required for	Description
PMLS_CLOB_PRIVATE_KEY	Trading	EOA private key for signing orders
PMLS_CLOB_API_KEY	Trading	Polymarket CLOB API key
PMLS_CLOB_API_SECRET	Trading	Polymarket CLOB API secret
PMLS_CLOB_API_PASSPHRASE	Trading	Polymarket CLOB API passphrase
FUNDER_ADDR	Trading	Funder wallet address (proxy wallet on Polygon)
POLY_ADDR	pos, pnl	Your Polygon wallet address for position lookups

Trading commands (marketo, limito, orders, cancel) require all five CLOB vars. Read-only commands (pos, pnl) only require POLY_ADDR.

Key Concepts

• Event slug: identifier for a top-level event (e.g. super-bowl-2025). One event contains multiple markets.
• Market slug: identifier for a single binary market (e.g. chiefs-win-super-bowl-2025).
• Token ID: large integer string identifying one side (outcome) of a binary market. Each binary market has exactly two token IDs (e.g. Yes and No).
• Outcome: human-readable label for one side of a market, e.g. "Yes" or "No" (case-insensitive in CLI).
• Price convention: all --price arguments are in cents (0–100). The CLOB API uses 0–1 internally; the CLI converts automatically.

---

Commands

get-markets <event-slug>

Resolve an event slug to its constituent market slugs.

pmls get-markets <event-slug>

Output — one market slug per line on stdout:

chiefs-win-super-bowl-2025
eagles-win-super-bowl-2025

---

orderbook <market-slug>

Fetch and display the L2 orderbook for all outcomes of a market.

pmls orderbook <market-slug> [--depth N] [--once|-o]

Argument	Default	Description
market-slug	required	Market slug to fetch
--depth N	3	Price levels per side (1–10)
--once / -o	off	Fetch once and exit; omit for continuous 0.5 s polling

Output format — repeated per outcome:

Outcome: Yes (Token: <token-id>)
Timestamp: 2025-01-01 12:00:00:000000
Asks
| PRICE|       SIZE|
|  63.0|      100.0|
|  62.5|      200.0|

Bids
| PRICE|       SIZE|
|  61.0|      150.0|
|  60.5|       80.0|

Asks are sorted ascending (best ask last, i.e. closest to mid at the bottom). Bids are sorted descending (best bid first).

marketo

Place a market order (Fill-or-Kill) filled immediately at the best available price.

pmls marketo --bet <amount> --side <BUY|SELL> \
  (--token-id <id> | --slug <slug> --outcome <name>) \
  [--price <cap-cents>]

Argument	Required	Description
--bet	Yes	USDC to spend (BUY), or number of shares to sell (SELL). Pass -1 with --side SELL to sell the entire position.
--side	No (default BUY)	BUY or SELL
--token-id	One group required	Token ID to trade directly
--slug + --outcome	One group required	Market slug and outcome name; resolved to a token ID via GAMMA API
--price	No	Max buy price cap in cents (0–100). BUY only; order is rejected if best ask exceeds this.

Output on success:

Note: Marketable orders in sport market are delayed by 3 seconds.
BUY order <order-id> submitted.

Output on failure: Polymarket server error message to stderr, exit code 1.

---

limito

Place a GTC limit order at an explicit price.

pmls limito --bet <amount> --price <cents> --side <BUY|SELL> \
  (--token-id <id> | --slug <slug> --outcome <name>)

Argument	Required	Description
--bet	Yes	USDC to spend (BUY), or number of shares to sell (SELL). Pass -1 with --side SELL to sell the entire position.
--price	Yes	Limit price in cents (0–100)
--side	No (default BUY)	BUY or SELL
--token-id	One group required	Token ID to trade directly
--slug + --outcome	One group required	Market slug and outcome name

Output on success:

BUY order <order-id> submitted.

---

orders

List all open (resting) orders.

pmls orders

Output format — one order per line:

<outcome> <side> <size>@$<price>, token ID: <token-id>

Example:

Yes BUY 100@$0.62, token ID: 10667...

---

cancel

Cancel open orders.

pmls cancel --all
pmls cancel --id <order-id>[,<order-id>,...]

Argument	Description
--all / -a	Cancel every open order
--id	Comma-separated list of order IDs to cancel

Output on success:

Canceled 2 order(s): <id1>, <id2>

Per-order failures are printed to stderr:

Not canceled <id>: <reason>

---

trade

List trade history.

pmls trade [--token-id <id>] [--before <unix-ts>] [--after <unix-ts>] [--market <market-id>] [-q <keyword>]

--token-id	Filter to a specific token ID
--before	Unix timestamp upper bound
--after	Unix timestamp lower bound
--market	Filter by market ID
-q <keyword>	Keyword filter matched against outcome name or market description (case-insensitive).
