name: so1964p2.nx.link
description: This host provides two reference-data endpoints for the Poloniex exchange: one returning live mark prices for all cross-margin symbols, and one returning static market metadata (symbol list, trade constraints, margin eligibility) for all trading pairs. Both endpoints require no inputs and return bulk data covering the full Poloniex market universe.

# so1964p2.nx.link

so1964p2.nx.link is a lightweight Poloniex market-data host serving agents that need exchange-wide symbol metadata or current mark prices for cross-margin trading pairs. It covers two distinct data types — static market structure and live mark pricing — with no filtering or single-symbol lookup capability. It is suited for agents doing broad market screening, margin position evaluation, or symbol validation against Poloniex's full tradable universe.

## When to use this host

Use this host when an agent needs exchange-wide Poloniex market metadata (symbol list, order constraints, margin eligibility) or bulk mark prices for cross-margin pairs. Do not use it for single-symbol price lookups, real-time bid/ask quotes, order book depth, trade history, or historical OHLCV data — those require a different data source such as a Poloniex ticker or market-data API with per-symbol and historical endpoints. This host returns only bulk, snapshot data with no filtering parameters.

## Capabilities

### Market Structure

Provides the full catalog of Poloniex trading pairs with metadata including base/quote currencies, trade state, order size constraints, and cross-margin eligibility and leverage limits.

- **`fetch-poloniex-market-symbols`** — Returns the full list of Poloniex trading market symbols with metadata including base/quote currencies, trade state, price/quantity scales, min order limits, and cross-margin support.

### Mark Price Feed

Returns the latest mark price and timestamp for every Poloniex cross-margin symbol in a single bulk response, enabling broad price-level screening and margin position monitoring.

- **`fetch-poloniex-mark-prices`** — Returns the latest mark price and timestamp for all Poloniex cross-margin trading symbols in a single array.

## Workflows

### Cross-Margin Symbol Screening

*Use when an agent needs to identify cross-margin eligible symbols and then evaluate their current mark prices in a single pass — for example, to find margin pairs trading above or below a target price level.*

1. **`fetch-poloniex-market-symbols`** — Retrieve all Poloniex symbols and filter to those with cross-margin support and desired leverage or quote currency constraints.
2. **`fetch-poloniex-mark-prices`** — Fetch current mark prices for all symbols and cross-reference against the filtered symbol list to evaluate price levels for the eligible cross-margin pairs.

## Skill reference

### `fetch-poloniex-mark-prices`

**Poloniex Mark Price** — Returns the latest mark price and timestamp for all Poloniex cross-margin trading symbols in a single array.

*Use when:* Use when an agent needs current mark prices across all Poloniex cross-margin pairs (e.g., to evaluate margin positions, screen for price levels, or monitor a broad set of symbols including USDT and BTC quote pairs).

*Not for:* Do not use for a single-symbol price lookup if bandwidth is a concern — this endpoint returns all symbols at once. Not suitable for historical price data or order book depth.

**Returns:** Returns a JSON array of objects, each containing symbol, markPrice (decimal string), and time (Unix ms timestamp) for every Poloniex cross-margin trading pair.

**Example:** `GET https://so1964p2.nx.link/markets/markPrice`

### `fetch-poloniex-market-symbols`

**Poloniex Market Symbols** — Returns the full list of Poloniex trading market symbols with metadata including base/quote currencies, trade state, price/quantity scales, min order limits, and cross-margin support.

*Use when:* Use when an agent needs to enumerate all available Poloniex trading pairs, check whether a specific symbol is tradable, retrieve order size and amount constraints, or determine cross-margin eligibility and max leverage for a market.

*Not for:* Do not use for real-time price quotes or order book data; this endpoint returns static market metadata and trade limits, not live bid/ask prices or ticker data.

**Returns:** Returns a JSON array of all Poloniex market objects, each containing symbol, base/quote currency names, trade state, visible/tradable start timestamps, symbolTradeLimit constraints, and crossMargin settings.

**Example:** `GET https://so1964p2.nx.link/markets`
