# On-Chain Market Config

## Get market config

```
GET /api/v1/config
```

Returns on-chain exchange configuration for the current `chainId + productType` scope: cashier buffers, exchange fee settings, and per-token cashier limits/rates.

Permission: `READ_ONLY`. No query parameters.

This endpoint is separate from direct on-chain stock reference-price reads. For the `StockOracle` contract interface, see [Stock Oracle](/rwa-trading-apis/market-data/stock-oracle.md).

## Response

Standard envelope. `data` contains:

| Field                | Type   | Description                                                    |
| -------------------- | ------ | -------------------------------------------------------------- |
| `cashierBuffer`      | object | Cashier-level buffer snapshot for instant deposit eligibility. |
| `exchangeFeeConfig`  | object | Exchange fee and minimum order settings.                       |
| `cashierTokenConfig` | object | Map of lowercase token address → per-token cashier config.     |

### Field naming note

`cashierBuffer` and each `cashierTokenConfig` entry use `chain`. `exchangeFeeConfig` uses `chainId`. Both represent the scoped chain ID.

### Value encoding

| Area                                                                 | Format                                | Example                                   |
| -------------------------------------------------------------------- | ------------------------------------- | ----------------------------------------- |
| `cashierBuffer.creditBuffer`, `creditBufferCapacity`, `totalBalance` | Raw WAD integer strings (18 decimals) | `"743810467000000000000"` ≈ 743.81 `mUSD` |
| `cashierTokenConfig.withdrawalBuffer`, `withdrawalBufferCapacity`    | Raw integer strings in token decimals | `"253689533"` with `decimals: 6`          |
| `exchangeFeeConfig.mintFeeRate`, `protocolFeeRate`, `minOrderValue`  | Human-readable decimal strings        | `"0"`, `"0.001"`                          |
| `cashierTokenConfig.depositRate`, `withdrawalRate`                   | Human-readable decimal strings        | `"1"`, `"0.9969"`                         |

Do not parse WAD or token-amount fields as human-readable decimals.

Per-token `withdrawalBuffer` values live under `cashierTokenConfig`, not in this object.

### `exchangeFeeConfig`

| Field             | Type   | Description                                                                                               |

Use `minOrderValue`, `mintFeeRate`, and `protocolFeeRate` when validating or displaying order economics before calling order endpoints.

### `cashierTokenConfig` entries

Map keys are lowercase ERC-20 token addresses. Each value includes:

| Field                      | Type    | Description                                                             |

Check `depositPaused`, `withdrawPaused`, and buffer fields before building deposit or withdrawal calldata. See [cash deposits](/rwa-trading-apis/cash-operations/deposits.md) and [withdrawals](/rwa-trading-apis/cash-operations/withdrawals.md).

## Integration notes

* For instant vs queued cash behavior, pair buffer fields here with [buffer mechanism](/rwa-trading-apis/cash-operations/buffer-mechanism.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.monday.trade/rwa-trading-apis/market-data/on-chain-config.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
