## Request

```bash theme={null}
curl "https://inkypump.com/api/capabilities?chainId=57073"
```

## Safe use

```ts theme={null}
const response = await fetch(
  "https://inkypump.com/api/capabilities?chainId=57073",
  { cache: "no-store" },
)
if (!response.ok) throw new Error(`Capabilities failed: ${response.status}`)

const data = await response.json()
if (data.chainId !== 57073) throw new Error("Wrong response chain")
if (!data.flags?.create) throw new Error("Creation is disabled")
if (data.activeCreationDeployment?.status !== "active") {
  throw new Error("No active creation deployment")
}

const hook = data.activeCreationDeployment.hook
```

<Warning>
  `activeCreationDeployment` is for new native launches. Existing tokens use their own `hook_address`. xStocks hooks come from `/api/xstocks/quote-assets`, not this field.
</Warning>

Responses send `Cache-Control: private, no-store`. Keep only a short-lived server cache if your application needs one.
