## Matched markets

`GET /cross-platform/matches`

Retrieve matched markets with a configurable confidence threshold. Matches use offset pagination and return a data array with meta containing total, count, limit, and offset.

| Name | Type | Description |
| --- | --- | --- |
| `limit` | number · default 20 | Results to return, from 1 to 100. |
| `offset` | number · default 0 | The number of matched pairs to skip. |
| `minScore` | number · default 0.35 | Minimum match score, from 0 to 1. |
| `search` | string · optional | Text search, up to 200 characters. |
| `verifiedOnly` | string · optional | Set to true to restrict results to verified matches. |

```

## Price divergence

`GET /cross-platform/arbitrage`

Query matched markets whose quoted probabilities diverge by at least your threshold. A minDivergence of 0.03 represents three percentage points.

| Name | Type | Description |
| --- | --- | --- |
| `limit` | number · default 20 | Results to return, from 1 to 100. |
| `minDivergence` | number · default 0.03 | Minimum probability divergence, from 0 to 1. |
| `minScore` | number · default 0.5 | Minimum matched-market confidence, from 0 to 1. |

> **Compare the market terms.** Price divergence is an analytical observation. Match confidence, settlement conditions, fees, liquidity, and execution timing all affect whether two positions are economically comparable.

## Venue coverage

Cross-venue matching currently covers Kalshi and Polymarket. Market discovery and wallet endpoints have their own datasets; a matched pair does not imply identical analytics coverage on both venues.
