Answers the automated market makers on one chain: their two tokens, their fee tier,
and what has moved through each.

The two price fields on a pool are the ratio its own reserves stand at, as the
indexer computed them. They are not a price ON either token and not a mark: nothing
here derives one, ranks the pools, or names a route through them.

A chain with no market maker deployed answers `read` with no pools. That is the
chain's real condition, and it is deliberately not the same answer as an indexer
that could not be asked.

## Request

1 field.

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

```bash
hanzo market pools
```

**SDK**

**.ts**

```ts
import { Configuration, MarketApi } from 'hanzoai';

const api = new MarketApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getMarketPools();
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import MarketApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = MarketApi(client).get_market_pools()
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.MarketAPI.GetMarketPools(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, market_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = market_api::get_market_pools(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.MarketApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new MarketApi(client).getMarketPools();
```

**HTTP**

```bash
curl https://api.hanzo.ai/v1/market/pools \
  -H "Authorization: Bearer $HANZO_API_KEY"
```

**MCP**

MCP reaches **market** through the `market` tool, which names its 3 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "list_market_chains"
         }
       }
     }'
```
