# Polymarket API

> Raw Polymarket data with platform-native fields like condition_id, clob_token_ids, and tx_hash.

These endpoints return **raw Polymarket data** directly from the Gamma API without normalization. Use them when you need platform-specific fields that the unified API strips out.

## When to use native endpoints

| Use case                             | Endpoint                              |
| ------------------------------------ | ------------------------------------- |
| Cross-platform dashboards, analytics | Unified API (`/v1/markets`)           |
| Polymarket trading bots              | Native API (`/v1/polymarket/markets`) |
| On-chain tracking, token operations  | Native API (`/v1/polymarket/markets`) |

## Platform-specific fields

| Field            | Type      | Description                                     |
| ---------------- | --------- | ----------------------------------------------- |
| `conditionId`    | string    | CTF condition ID (used for on-chain operations) |
| `clob_token_ids` | string\[] | CLOB token IDs for Yes/No outcomes              |
| `outcome_prices` | string    | JSON-encoded outcome prices                     |
| `question`       | string    | Full market question text                       |
| `slug`           | string    | URL slug on polymarket.com                      |
| `tokens`         | object\[] | Token details with `token_id` and `outcome`     |
| `neg_risk`       | boolean   | Whether market uses neg-risk framework          |

## ID mapping

Every unified market with `platform: "polymarket"` has an ID formatted as `poly_{condition_id}`. Strip the `poly_` prefix to get the `condition_id` for native endpoints.
